Vijay: When exome sequencing was starting to be done routinely around 2009, we reasoned that Diamond-Blackfan anemia would be an ideal disease to study using this approach. At the time, only a few ribosomal protein mutations had been described in this disease and we thought that such sequencing approaches could help us better define the pathogenesis of this disorder. We did identify some non-ribosomal protein mutations through focused efforts (e.g. GATA1), but we kept sequencing more individuals to more comprehensively define the genetic landscape of this blood disorder. This paper describes the comprehensive analysis of the full cohort of individuals we studied.

AJHG: What about this paper most excites you?

Vijay: There are three things that excite me most about this work. First, this paper is really the culmination of several years of incredibly hard work by a number of talented trainees in our group, as well as fabulous colleagues. It is great to see their work put together and presented so nicely. Second, I think this analysis can serve as a model for other systematic studies in cohorts of individuals with a range of rare diseases. It provides a framework for thinking about how to perform comprehensive analyses in rare disease cohorts, while also illustrating major challenges in trying to define genetic etiologies. Third, I think the work nicely outlines the future directions we hope to take to better define the genetic causes for the remaining ~20% of cases and understand the basis for the variable penetrance observed.

AJHG: Thinking about the bigger picture, what implications do you see from this work for the larger human genetics community?

Vijay: We have examined a rather large cohort of ~470 individuals with a rare disease that occurs in ~1 in 200,000 live births. This cohort took many years to put together and required extensive international collaborations. Despite the considerable size of this cohort (for a rare disease), we still could not define the potential genetic etiology for a number of individuals in the cohort. Our burden analyses nicely show how we are sufficiently powered to detect mutations in the exome that explain > 5% of cases in the cohort. Given all of this, our findings emphasize the need for larger analyses of such rare diseases. This can only happen through collaboration. Different investigators need to be willing to come together to maximize our ability to identify additional genetic causes for rare diseases. While many in the human genetics community appreciate the importance of such efforts, I still find that many colleagues in my clinical field and others are hesitant to share data. As a physician, I realize that doing so is critical for all patients and individuals affected by rare diseases.

AJHGWhat advice do you have for trainees/young scientists?

Vijay: Probably the most useful advice I can offer is that any trainee should pursue problems and work in environment where they can most enjoy their work. I have been incredibly fortunate to work in environments, both as a trainee and faculty member, where I have been given the freedom to pursue problems I am passionate about. As a result, I have also tried to create an environment in the lab that can enable trainees to do the same, which I believe is very important.

AJHG: And for fun, tell us something about your life outside of the lab.

Vijay: One of the things I enjoy outside of lab is exploring the fantastic restaurants in Boston and listening to jazz music (particularly when it is live).

Inside AJHG: A Chat with Jonathan Mill

Posted By: Sarah Ratzel, PhD, Science Editor, AJHG 

Each month, the editors of The American Journal of Human Genetics interview an author(s) of a recently published paper. This month, we check in with Jonathan Mill to discuss his paper, “Leveraging DNA-Methylation Quantitative-Trait Loci to Characterize the Relationship between Methylomic Variation, Gene Expression, and Complex Traits.”

AJHG: What caused you to start working on this project? 

Jonathan: Our lab studies the genomic basis of complex human diseases, and we’re particularly interested in the mechanisms underpinning transcriptional regulation. The last decade has seen tremendous advances in understanding the role of common genetic variation in health and disease, but genome-wide association studies (GWAS) don’t always identify specific causal genes, and we know that the variants associated with disease are likely to influence gene expression rather than causing changes to the transcribed protein. We have been quantifying genetic and epigenetic variation in large numbers of samples and have been thinking about ways of integrating these datasets to fine-map GWAS regions.

This project built on our previous work using DNA methylation quantitative trait loci (mQTLs) to interpret the functional consequences of common genetic variation associated with neuropsychiatric disease and other human traits. We generated blood mQTL data in the Understanding Society UK Household Longitudinal Study (UKHLS) and used these to refine genetic association data from publicly available GWAS datasets in order to prioritize genes involved in complex traits and diseases. We also sought to identify pleiotropic relationships between DNA methylation and variable gene expression by using publicly available whole-blood gene expression QTL (eQTL) data.

AJHG: What about this paper most excites you? 

Jonathan: First, we have generated an extensive mQTL dataset, using the new Illumina EPIC DNA methylation array to identify over 12 million associations between genetic variants and DNA methylation sites, including a large number not identified by previous DNA methylation-profiling methods. We show that there are many instances of shared genetic signals on neighboring DNA methylation sites and that these associations are structured around both genes and CpG islands. We hope these will be a valuable resource for the genetics community, and our data can be downloaded from our website.

Second, we demonstrate the utility of these data for interpreting the functional consequences of common genetic variation associated with human traits by using summary-data-based Mendelian randomization (SMR) to identify >1500 pleiotropic associations between complex traits and DNA methylation sites. Finally, we use these data to explore the relationship between DNAm and gene expression by using genetic instruments rather than correlations to infer associations between specific DNA methylation sites and genes.

AJHG: Thinking about the bigger picture, what implications do you see from this work for the larger human genetics community?

Jonathan: Our results add to an increasing body of evidence showing that genetic influences on DNA methylation are widespread across the genome. We show that integrating these relationships with the results from GWAS of complex traits and genetic studies of gene expression can improve our understanding about the interplay between gene regulation and expression and facilitate the prioritization of candidate genes implicated in disease etiology.

AJHG: What advice do you have for trainees/young scientists?

Jonathan: Most importantly, pick a subject you are passionate about and make sure your science continues to be fun! The biggest and best-funded labs are not necessarily the best places to train; research is all about teamwork and collaboration, and to me, these are key attributes that trainees and young scientists should look for in selecting a place to study and learn. Don’t be afraid to be wrong, and you should never worry about questioning your supervisor or mentor; I have learned so much from the exceptional postdocs and students in my lab who generally know a lot more than I do! Finally, make sure you keep a good work-life balance; it’s important to switch off and realize there is more to life than grant funding and papers.

AJHG: And for fun, tell us something about your life outside of the lab.

Jonathan: I live in a small fishing village on the Devon coast just outside Exeter in the UK. When I’m not trying to understand gene regulation in the brain, I spend a lot of time in my allotment attempting to grow enormous vegetables. I also cycle a lot, and last year rode to Paris from the UK along with Eilis Hannon (first author on this paper) to raise money for the amazing Alzheimer’s Society who fund our work into dementia.

Announcing: AJHG “Perspectives” Series on Issues Confronting Human Genetics and Influencing Research

Posted By: David L. Nelson, ASHG President 

As part of our ongoing commitment to address how genetic findings are used in society and to foster discussion within the field and the public, I am pleased to announce that ASHG is launching a new “Perspectives” series of short statements this month, which will be published periodically in The American Journal of Human Genetics.

The first topic targets disturbing and scientifically flawed attempts to link genetics with racial supremacy. The statement denounces such attempts, stating that there can be no genetics-based support for claiming one group to be superior to another.

Read the statement on AJHG’s website.

We decided to address this important issue in the series’ first statement, recognizing that there has been a resurgence of bogus claims that racial supremacy has scientific roots. The statement explains that humans cannot be divided into biologically-distinct subcategories, given the considerable genetic overlap among members of different populations, and asserts clearly that genetics exposes the concept of ‘racial purity’ as scientifically meaningless.

This statement reflects a continuation of ASHG’s objection, over decades, to the misuse or twisting of human genetics findings for political or social ends, including past ASHG statements on genetics, ancestry, and intellectual ability and the consequences of eugenics; and more recently, my piece in the September member newsletter on the Society’s origins and early discussion of its purpose and role.

AJHG Perspectives: A Channel for Timely Discussion

Statements in the new series will address a variety of important topics in human genetics and its interface with society, reinforcing the Society’s and Journal’s role as a leading source of emerging human genetics science. They will offer timely, concise viewpoints on topics in research, health, and society that have been prioritized by the Board; will address how scientific research informs those issues; and may assert Society policy positions or note important related field activities.

Statements will also refer readers to a range of lengthier academic or other relevant work. They do not strive to cover the breadth and depth of each issue but rather to draw on, complement, and highlight the need for continuing research and member engagement.

AJHG has long been a leading home for discussion and debate about emerging science across human genetics. We are enthusiastic about this new feature, which will help ensure that scientific facts, findings, and open discussion inform larger societal dialogue,” said Bruce Korf, MD, PhD, Editor-in-Chief of AJHG.

Read an editorial announcing the new Perspectives series.

Fostering Discussion Within and Outside the Scientific Community

As research in human genetics continues to advance, it is opening new pathways of understanding and treatments that are saving lives. At the same time, ASHG has long been committed to addressing how these findings may be used in society, and we hope this new series will spark individual scientists to be increasingly vocal in discussing what the science does, might, and doesn’t say about a wide range of important issues, even—perhaps especially—when there is disagreement.

Individual members of our Society are knowledgeable, thoughtful, outspoken, and diverse in their views – these are the traits that push our field forward and help us collaboratively and thoughtfully address complex issues. Members, I encourage you to speak out, in your own voices, to represent your individual views as genetics experts on this and other important topics.

Given ASHG’s broad community of researchers, clinicians, ethicists, and other professionals, we anticipate perspectives on many topics may spark a diversity of dialogue, with strongly held perspectives on the science. We look forward to continuing that discussion through the pages of AJHG and hope to spark ongoing, constructive dialogue in the laboratory, classroom, clinic, and across the broad range of colleagues interested in human genetics.

Inside AJHG: A Chat with Sek Kathiresan

Posted By: Sara Cullinan, PhD, Deputy Editor, AJHG

Each month, the editors of The American Journal of Human Genetics interview an author of a recently published paper. This month we check in with 2018 Curt Stern Award winner Sek Kathiresan (@skathire on Twitter) to discuss his paper ‘Genetic Association of Albuminuria with Cardiometabolic Disease and Blood Pressure’.

AJHG: What prompted you to start working on this project? 

Sek: In observational studies, many biomarkers including the concentration of protein spilling into urine (albuminuria) are correlated with health outcomes. We wondered if the association of albuminuria with adverse health outcomes reflected a causal relationship or mere correlation. Knowing this is important to determine if decreasing urinary albumin excretion should per se be a target for therapeutic intervention.

AJHG: What about this paper/project most excites you? 

Sek: In addressing the question above, we identified a bi-directional relationship – genetic predisposition to albuminuria leads to higher blood pressure and genetic predisposition to higher blood pressure leads to more albuminuria. We suspect this reflects a feed-forward loop.

AJHG: Thinking about the bigger picture, what implications do you see from this work for the larger human genetics community?

Sek: Mendelian randomization is a useful genetics approach for causal inference. The availability of biomarkers, clinical outcomes, and genetic data in a single large study – UK Biobank – is facilitating systematic Mendelian randomization analyses for a range of biomarkers.

AJHG: What advice do you have for trainees/young scientists?

Sek: Pick an important problem to study – one that not only you care about but also the rest of the world. Figure out the skills and resources you need to address the problem. Then, go out and get the training and resources to attack the problem. Stay focused on the problem and ask yourself, each day, if you are working on the most impactful thing you could be doing.

AJHG: And for fun, tell us something about your life outside of the lab.

Sek: Life outside the lab is consumed by three children – ages 15, 13, 10. Raising them to be happy, loving, and engaged with the world is a joy.

Inside AJHG: A Chat with David Kingsley

Posted By: Sara Cullinan, PhD, Deputy Editor, AJHG

Each month, the editors of The American Journal of Human Genetics interview an author of a recently published paper. This month we check in with David Kingsley to discuss his paper ‘Characterization of a Human-Specific Tandem Repeat Associated with Bipolar Disorder and Schizophrenia’.

AJHG: What prompted you to start working on this project? 

David: We’ve been working on the genomic basis of evolutionary change for many years. We previously found that the deletion of key regulatory sequences can underlie classic evolutionary traits in both stickleback fish and humans. [Co-authors] Craig Lowe and Janet Song decided to look for the reciprocal type of molecular changes: insertion or gain of new regulatory sequences that might contribute to human-specific traits.

AJHG: What about this paper/project most excites you? 

David: We found a particularly dramatic human insertion in an important calcium channel gene. Where most primates have a single, 30 base pair, non-coding sequence, humans have expanded the 30-mer into a huge tandem array that can be up to 30,000 base pairs long. We found that the expanded human sequence shows enhancer activity in neural cells, suggesting it contributes to increased expression of this calcium channel gene in humans compared to other primates.

We were particularly interested to see that the tandem array is located right between SNP markers that been repeatedly associated with risk of schizophrenia and bipolar disorder in many human genome-wide association studies. We found that different subtypes of the tandem arrays are associated with risk or protective genotypes at the locus, and that the risk-associated arrays have less enhancer activity than other subtypes. We think that this novel structural feature may thus contribute not only to evolutionary differences between humans and other primates, but also to common risk of psychiatric disease within human populations.

AJHG: Thinking about the bigger picture, what implications do you see from this work for the larger human genetics community?

David: These large tandem arrays don’t appear in the reference human genome, likely because they are unstable when propagated in conventional bacterial vectors, and are impossible to assemble correctly from short sequence reads alone. Conventional SNP genotyping arrays don’t score the repeats, and exome sequencing studies miss the region entirely because the arrays are located in a large intron of a calcium channel gene.

The human-specific arrays are thus a great example of a previously hidden genome feature, that may nonetheless provide a causal basis for functional changes in the gene. The broader lesson is that the human reference genome is still a work in progress, and that lots of important biology may be embedded in the parts of our genomes that are difficult to assemble and still poorly understood.

AJHG: What advice do you have for trainees/young scientists?

David: Treasure your exceptions, and try to keep an open mind when studying any research problem. The surprises and the things that don’t initially make sense are interesting puzzles that often lead to new discoveries. But you have to embrace results that don’t fit your preconceptions, and then be willing to consider a whole range of new possibilities.

AJHG: And for fun, tell us something about your life outside of the lab.

David: I love to explore the sky with telescopes at night and have made trips all over the world to enjoy dark skies in both the Northern and Southern hemisphere. Early astronomers slowly groped their way to a better understanding of the larger universe by cataloging individual stars, planets, and nebula with relatively simple equipment. Particular objects can look like stunning “eye-candy” or faint and subtle “mind-candy” in the eyepiece. And as you look at more and more objects, you can gradually build up a larger picture of our place in the solar system, the Milky Way galaxy, and the overall universe.

That actually has lots of parallels to biology. In genetics, we often start with an interest in particular traits or genes. But detailed studies of particular genes can grow into larger studies of chromosomes, whole genomes, variation between individuals, and the molecular basis of evolutionary differences between species. Our glimpses of the whole shebang are still very incomplete. But spend enough fun time looking at stars and genomes, and you end up with a much richer view of humans and where we came from.

Inside AJHG: A Chat with Levi Teitz and David Page

Posted By: Sarah Ratzel, PhD, Science Editor, AJHG 

Each month, the editors of The American Journal of Human Genetics interview the author(s) of a recently published paper. This month, we check in with Levi Teitz and David Page to discuss their paper “Selection Has Countered High Mutability to Preserve the Ancestral Copy Number of Y Chromosome Amplicons in Diverse Human Lineages.”

20180820_LeviTietz-DavidPage

AJHG: What caused you to start working on this project? 

Levi: Our lab has a long history of studying the Y chromosome, but the ampliconic regions were always a bit of a mystery because of how difficult they are to study, due to their complex architecture and high sequence identity between copies. With the advent of high-throughput sequencing technologies and large, publicly available datasets, it seemed like a good time to revisit questions about amplicon variation and evolution with those new tools at our disposal.

David: The Y chromosome has been an enigma to geneticists for the last century, largely because it doesn’t play by the usual rules of being transmitted from both mother and father, and recombining with a homolog along its length, in meiosis. Despite being a sex chromosome, the Y chromosome is transmitted clonally – asexually – from father to son to son; it stands apart from all other nuclear chromosomes in this respect. This has led to all manner of unfounded insults regarding the Y chromosome’s character, medical relevance, and future prospects. My colleagues and I have spent decades defending the honor of the chromosome in the face of these insults.

AJHG: What about this paper most excites you? 

Levi: The new evolutionary questions it raises. The amplicons are extraordinarily divergent between species – so much so that it’s essentially impossible to reconstruct the steps that evolution took to get from the ancestral mammalian or primate amplicons to modern-day Y chromosomes. When we began this project, we expected that we could observe these evolutionary steps by looking within only humans. Instead, we found that the amplicon variation within human populations is an evolutionary dead end, and that the ancestral amplicon structure has been preserved for hundreds of thousands of years! This is a bit of a paradox: why is amplicon structure maintained in humans but so divergent between species? This is a hard problem, but solving it should provide incredible insight into amplicon evolution and function.

David: Learning something unanticipated about a subject you love is exciting. Massive palindromes and amplicons carrying spermatogenesis genes were known to dot the genomic landscape of the human Y chromosome, and they are frequently subject to deletion or rearrangement through non-allelic homologous recombination. The excitement for me here arises from both a computational advance and a biological insight. First, graduate student Levi Teitz, with guidance from Helen Skaletsky, mastered the computational challenge of robustly and accurately discerning the copy numbers of many different Y amplicons from whole-genome shotgun sequence data. Second, Levi applied these computational tools to the 1000 Genomes males, thereby characterizing Y amplicon copy number variation (CNV) around the globe. While the existence of such Y-amplicon CNV was unsurprising, the predominance of consistent patterns of Y-amplicon copy numbers around the globe (actually, across Y chromosome haplotypes) surprised me, and indicated that natural selection had optimized and consistently favored specific copy numbers for a host of Y amplicons. Natural selection, whose ability to maintain genes on the clonally transmitted Y had often been impugned, has evidently been effective at policing Y-amplicon copy numbers. Natural selection is alive and well on the human Y chromosome, even the parts where we might least expect it!

AJHG: Thinking about the bigger picture, what implications do you see from this work for the larger human genetics community?

Levi: Beyond improving our understanding of the Y chromosome, our work highlights the fact that the genome can change in unexpected ways. Much genomic research today focuses exclusively on the parts of the genome that are easiest to study: single-copy coding sequence. This paper demonstrates that not only does the rest of the genome have profound evolutionary and phenotypic effects, it also varies in ways that are exquisitely dependent on its repetitive structure. In fact, it would be impossible to understand the phenotypic and evolutionary stories without first understanding the underlying complex structure of these genomic regions. There are still parts of the human genome where complex structures are unresolved; who knows what we will discover when those parts are properly sequenced?

David: Genetically inclined students of human biology, medicine, and evolution tend to focus their efforts on the parts of the genome that are most readily analyzed – the civilized, single-copy parts that approach most closely our Mendelian expectations. But there is so much to be learned in the relatively understudied and untamed parts of the genome where palindromes, amplicons, and segmental duplications bend the rules, demanding special attention to technical and analytic matters but offering rich rewards to the curious and persistent.

AJHG: What advice do you have for trainees/young scientists?

Levi: I’m a trainee and a young scientist myself, so I don’t have much career experience to draw upon, but my advice would be to never forget the human factor when choosing what to work on and who to work with. If you are surrounded by good people and you enjoy working with them, your science will be better for it.

David: Work with people whom you like, respect, and admire, on questions that you personally find to be compelling. Nothing is more satisfying than finding value and meaning where others think not to look.

AJHG: And for fun, tell us something about your life outside of the lab.

Levi: I’m an amateur baker and have recently started accumulating kitchen gadgets, including a doughnut filling injector, a rotating cake stand, and a frying pan just for blintzes.

David: I love to explore the outdoors, and especially mountains and lakes, with family and friends, in all seasons. I would point out that some of our oldest and most acclaimed National Parks – Yellowstone and Yosemite – begin with the letter Y.

Inside AJHG: A Chat with Neil Hanchard

Posted By: Sara Cullinan, PhD, Deputy Editor, AJHG

Each month, the editors of The American Journal of Human Genetics interview an author of a recently published paper. This month, we check in with Neil Hanchard, a member of the ASHG Board of Directors and senior author of ‘Whole-Exome Sequencing Reveals Uncaptured Variation and Distinct Ancestry in the Southern African Population of Botswana.’

AJHG: What prompted you to start working on this project? 

Neil: Serendipity. The nidus for the project was the Human Heredity and Health in Africa (H3Africa project), sponsored by the NIH and the Wellcome Trust. Some of our institutional partners in Africa approached us about participating in order to gain insights to the genetics underpinning disease progression in childhood HIV, which, unlike its adult counterpart, hasn’t been extensively studied at the genomic level. They needed someone who knew something about genomic studies and Africa, and I happened to be standing nearby (almost literally). As we started looking for genetic variants influencing the phenotype, it became plainly obvious that without a genomic context, particularly for the individuals from Botswana, we would be going in circles.

AJHG: What about this paper/project most excites you? 

Neil: Two things. First, the degree of uncaptured variation and the unique demographic features in our populations is exciting – if we can exploit them properly, there’s a real prospect of identifying new genes and variants that are relevant to HIV progression in children – that could be a game-changer; second, all the analyses were done by trainees from Botswana and Uganda. They have since taken that genomics experience and expertise back to their home institutions, which bodes well for the future of genomic research in Africa.

AJHG: Thinking about the bigger picture, what implications do you see from this work for the larger human genetics community?

Neil: I hope it will make researchers and clinicians think more broadly about the genetic diversity across the continent. There’s a tendency in the field to think of ‘Africa’ as represented by the predominantly West African groups in publicly available datasets, but that’s only the proverbial tip of the iceberg. I hope this will give people a better understanding of the depth of diversity and genomic complexity that has to be considered in genetic studies of persons of African heritage.

AJHG: What advice do you have for trainees/young scientists?

Neil: I still think of myself as a ‘young scientist’, so I’d have to fall back on the words of my mentor as I was starting my lab – when I asked him what advice he had for me, he said, very unceremoniously, “don’t give up”. At the time, I recall thinking how incredibly underwhelming a response that was, but over time I’ve grown to see it as a genuine pearl of wisdom for a junior faculty (or trainee) enduring what can sometimes seem like a very long time in the academic wilderness.

AJHG: And for fun, tell us something about your life outside of the lab.

Neil: Is there life outside the lab? (jk!) Mostly, I spend my away-from-the-lab time with my family. Accompanying my wife to the various activities my sons are involved in – be it church choir, baseball, or chess – is really enjoyable. Otherwise, I like sports, so I try to make time to play or watch any of swimming, tennis, baseball, football…and on the few occasions when I get to go on vacation, I’m perfectly happy in Jamaica (where I’m from), reading a book beside the beach and listening to the waves crash.
