Inside AJHG: A Chat with Stephen Kingsmore

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 Stephen Kingsmore to discuss his paper “A randomized, controlled trial of the analytic and diagnostic performance of singleton and trio, rapid genome and exome sequencing in ill infants.”

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

Stephen: We’ve been working on implementing rapid whole genome sequencing in infants in intensive care units since 2011. We have two Guinness world records for fastest time to genetic diagnosis (the current benchmark is 19 hours). In the first 35 infants we tested, we saved two lives by changing therapy from that based on the clinical diagnosis to that based on the molecular diagnosis. Ever since then, we’ve been on a mission to understand how to make this reality in every intensive care unit in the world.

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

Stephen:  Randomized controlled trials are very exacting. This is just the second randomized controlled trial of clinical genome sequencing! You’re never sure whether a clinical trial will really test the desired hypothesis. I was most excited that we clearly showed that ultra-rapid whole genome sequencing, with fastest time to diagnosis, was best for seriously ill infants in intensive care units (ICUs). As with every previous study, I now know how to redo the current one!

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

Stephen: This manuscript is part of a growing body of evidence that demonstrates that infants in ICUs with diseases of unknown etiology benefit from rapid whole genome sequencing by virtue of the consequent implementation of precision medicine. We anticipate that 30,000 infants per year would benefit from this in the U.S. The current study was unique since almost one half of infants in ICUs were eligible for enrollment. As a result, we found that genetic diseases are much more common than previously expected.

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

Stephen: Think about a career in genomic medicine – the genomic medicine tsunami is coming and we’ll need every genetic counselor and medical geneticist to deliver this new type of care. For the first time, genomics will save lives day in, day out.

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

Stephen: I’m reading the Bible in a year. I’m 2/3 of the way through and it yields specific thoughts for each day, as well as continually adjusting my thinking to the bigger, long-term picture. It started as a chore and now is a vital part of my day.

Genomic Medicine at the Population Level: Your Questions Answered 

Posted By: Alissa Ortman, Associate Director, ASHG Digital Programs

Instagram-ad-Webinar-Large-Population-Genetics-cropped

In September, ASHG and The American Journal of Human Genetics (AJHG) hosted a webinar to discuss large-scale, national studies that have been launched to collect phenotypic and genomic data on large populations. They also discussed how the data from that work should be shared around the world. If you missed it, you canwatch the recording or read this blog that summarizes the event.

This topic generated numerous audience questions, not all of which were able to be answered. Fortunately, the All of Us Research Program communications team was able to answer some of them after the webinar.

Attendee Question: When will All of Us start recruiting from smaller cities across the country? Example: I live in Tallahassee, FL. and am interested in joining.

All of Us: Recruitment is now open nationwide at https://www.joinallofus.org/en. Meanwhile, the program is gradually expanding its reach to collect physical measurements and samples from more participants in different areas across the country and will invite more participants to schedule a visit in time.

Attendee QuestionHas any uninterpreted genomic data (not results) been returned yet to any All of Us participants? If so, how much? If not, when is that anticipated to begin?

All of Us: No, not yet. We have not yet begun genetic analyses, either genotyping or whole genome sequencing. Participants will be able to request access to their raw genetic data in time. Our plans and timeline for the return of information are currently under development and will be subject to review by our Institutional Review Board.

Attendee Question: Do you anticipate expanding the data All of Us will return to participants—specifically, in line with recent FDA guidance around pharmacogenomics?

All of Us: Over time, the program plans to return various types of information. Genetic results will likely include information about ancestry and traits, pharmacogenomics, and findings tied to 59 genes associated with risk of specific diseases for which there are established medical guidelines for treatment or prevention. The specific details about what the program will return and when are under discussion and will be reviewed by our Institutional Review Board.

Attendee QuestionIt is great that genomic data is being used in novel ways for diagnosis of rare, even new diseases. However, what efforts are being made to make novel treatment options available to the individual patients?

All of Us: The mission of the All of Us Research Program is to accelerate health research and medical breakthroughs, enabling individualized prevention, treatment, and care for all of us. We hope novel treatments will be discovered based on the data available through the program and understand that these options then need to get to the folks who need them most. In August 2019, All of Us awarded $4.6 million in initial funding to Color, a health technology company, to establish the program’s nationwide genetic counseling resource. Through this funding, Color’s network of genetic counselors will help participants understand what the genomic testing results mean for their health and their families.

Attendee QuestionWill any training sessions be available for how to use the cloud data of All of Us Project?  

All of Us: Once the Research Hub is made available to all researchers (anticipated for 2020), All of Us will announce plans for upcoming training sessions on how to use the platform.

Thank you to our webinar sponsor, Illumina, whose sequencing and array technologies are fueling advancements in life science research, translational and consumer genomics, and molecular diagnostics. For more information, please visit illumina.com or contact their population genomics team at populationgenomics@illumina.com.

 

Inside AJHG: A Chat with Heidi Rehm

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

Dr. Rehm: We (Broad Institute and Partners Laboratory for Molecular Medicine) as well as Baylor College of Medicine were funded to provide genomic sequencing and interpretation support for Phase 3 of the eMERGE program.

AJHG: What about this paper most excites you? 

Dr. Rehm: Understanding our genomes will require large scale data sharing, harmonization and analysis across many research and health systems. This paper represents key steps in harmonizing and scaling genomics in the context of real-life healthcare systems.

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

Dr. Rehm: We hope that our work sets the groundwork for more clinical laboratories standardizing the intake of genetic testing orders and output of clinical reports for consumption by electronic health systems which we hope will be embraced as we all try to best integrate genomics into the practice of medicine.

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

Dr. Rehm: Clinical genomics is an exciting field with tremendous growth happening. Come join us!

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

Dr. Rehm: I have two teenagers, so life outside the lab right now is mostly following them around to sports events and college visits. Most weeks I get to play at least one game of ultimate Frisbee in the evening when I’m not traveling. And of course a favorite family activity is watching John Oliver as the only way to survive the current political climate in the U.S.!

Advancing Research and Privacy: Achievements, Challenges, and Core Principles

Posted By: Les Biesecker, ASHG President

Today, ASHG issued a new Perspective in The American Journal of Human Genetics (AJHG) entitled, “Advancing Research and Privacy: Achievements, Challenges, and Core Principles”. In the Perspective, the ASHG Executive Committee emphasizes the tremendous value of data sharing to advance genetics and genomics research, and the ongoing and unwavering commitment of members of our field to protecting the privacy of research participants. It also articulates core privacy principles that the Society believes should apply to all human genetics and genomics research.

20190905_privacy-perspective-page
ASHG’s newest Perspective appeared today in AJHG.

This Perspective is timely given the current global debate on data privacy and the many countries establishing new broad citizen privacy protections, the European General Data Protection Regulation (GDPR) being a notable example. Within these discussions, it is important to emphasize that genetic privacy in publicly funded research is well-regulated and researchers are careful custodians of research participants’ genetic information. It behooves us, both in the U.S. and in other countries, to monitor proposed policies to ensure they balance important consent and privacy protections with the vital health and medical benefits that can come from genetics and genomics research.

The new Perspective notes that, within the U.S., many genetic privacy laws apply only to federally funded research. Increasingly, researchers in our community—both in academia and industry—recognize the potentially useful role of data generated by entities that are not federally funded to pursue shared health goals. We believe these data should be secured using standards equivalent to those for federally-funded entities.

Thus, to enable these data to be collected ethically and benefit all consumers through future improved health and medicine, ASHG believes the core principles described in the Perspective should apply to all genomic research, irrespective of the funding source. The Society was encouraged by recent efforts by a collective group of private companies to develop core privacy principles, and ASHG is eager to foster further dialogue to advance research data privacy policies that advance the shared values of the research community and adhere to informed consent and privacy best practices.

This is the third in the Perspectives series. We look forward to continuing the dialogue on important policy issues at the Annual Meeting, through AJHG, and other venues.

Inside AJHG: A Chat with Natalie Telis

Posted By: Sarah Ratzel, PhD, Science 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 Natalie Telis to discuss her paper, “Public Discussion Affects Question Asking at Academic Conferences.”

20190717_NatalieTelis

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

Dr. Telis: At one of the first conferences I went to, I realized after a day that I was the only woman who’d asked a question. And I remember thinking, “That’s weird, right?”

But then I second guessed it. I said, well, there were maybe 10 questions today. If 1 in 10 people in the audience are women, that participation is actually representative. What information would I need about this conference to discover whether this is representative participation?

Part of being a computational biologist is that you have a skill set that applies to computational problems — not just biology problems. So I started drawing on that skill set to try to learn more about this problem, and things kind of evolved from there!

AJHG: What about this paper most excites you? 

Dr. Telis: I am really excited about the opportunity to explicitly set goals, and then to use these techniques to measure whether our interventions get there. If our goal is to increase proportionate participation, it’s easy to say: “Well, having 50% of people in the room be women will help us get there.” But does that actually come to bear? We can test that question now (and learn that it doesn’t work that way). That can help us build powerful interventions to change culture and reshape access for underrepresented groups in science more broadly.

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

Dr. Telis: The human genetics community is still grappling with questions about representation and participation across the board, not only for women scientists but across intersectional categories. I do hope that raising these questions in a scientific way has contributed to more discussion around inclusion and representation. We definitely still need to ask, what do we want our community to look like, and how do we get there?

This work provides a precedent and hopefully a computational framework for testing that. And that’s a critical infrastructure we need to develop as we attempt to create change.

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

Dr. Telis: Any question is an opportunity to hone your scientific skills. Asking questions about questions didn’t seem like human genetics to me, but the computational techniques I’ve learned were ultimately what I used to solve that problem. Being a scientist is an opportunity to live and work on the edge of what is known — bring that curiosity in the face of uncertainty with you wherever you go!

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

Dr. Telis: I don’t really believe in New Year’s resolutions or setting a goalpost (especially because I always miss them), so instead this year I started trying to numerically track things I want myself to do more of. So I’m surprised and shocked and very proud to say I’ve read 27 books so far this year! Making space for all that fiction reading, not just paper reading, has made me more refreshed, inspired, and creative in my research.

Inside AJHG: A Chat with Lluis Quintana-Murci

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 Lluis Quintana-Murci (@quintanamurci) to discuss his paper “Impact and Evolutionary Determinants of Neanderthal Introgression on Transcriptional and Post-Transcriptional Regulation.”

Lluis Quintana-Murci

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

Lluis: My laboratory is interested in the evolution of human populations and their long-standing relationship with infectious agents; half of the lab thus works on population genetics questions and the other half focuses more on population/systems immunology. In the context of this project, it all started back in 2016, when we found that Neanderthal introgression has affected innate immunity genes as a whole, and that some innate immunity genes (e.g., the TLR1/6/10 cluster) display extremely high levels of Neanderthal ancestry (Deschamps et al. Am J Hum Genet, 2016).

Later that year, we also found that Neanderthal introgression has been pervasive among regulatory variants (eQTLs), in particular those involved in responses to viral stimuli including influenza (Quach et al. Cell, 2016). The next natural question was then to explore how Neanderthal-introgressed variants in the genomes of non-Africans have affected more generally transcriptional and post-transcriptional regulation, focusing on promoters, enhances and miRNA-mediated regulation, in different tissues and cell types.

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

Lluis: Several things. First, although Neanderthal introgression has had relatively little effect on miRNA-mediated regulation, a mechanism that in general tolerates little variation and is highly evolutionary constrained, a few Neanderthal variants in a few miRNAs can exert a massive impact on downstream transcriptional programs. In general, I am fascinated by the fine-tuned “smart” way miRNAs function.

Second, I am excited about our results of enhancers, in particular the enrichment in Neanderthal ancestry we find in enhancers that are active in T cells (yes, sorry, I have a biased interest in all immune-related processes). What is even more interesting is that the excess of Neanderthal ancestry we observe in T cell enhancers is not due to increased Neanderthal introgression. Instead, it results from a higher human-Neanderthal divergence at these elements. This may reflect past adaptation in the Neanderthal lineage for this type of enhancers.

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

Lluis: This work highlights once more the potential benefits of admixture between our ancestors and other human forms, such as Neanderthals or Denisovans. The latter were adapted to their environments, whereas our ancestors entering Europe or Asia were less adapted. In this context, acquiring advantageous variation through archaic admixture is a fascinating topic, with obvious consequences for the larger human genetics community. Indeed, such archaic admixture increasingly is being shown to affect molecular phenotypes such as gene expression or mechanisms of gene regulation (e.g., this study) and more generally, organismal phenotypes such as traits and diseases (e.g., skin pigmentation, sleeping patterns, allergies) in present-day human populations.

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

Lluis: Be open while doing research, be curious, be rigorous, exchange a lot with other trainees and PIs, read a lot, and MAINLY, have fun and be passionate! Meaning both in your working and non-working life. Enjoy the work, do not suffer from it! For me, this is rule number one. If you follow this rule, great findings will follow…and, yes, a bit of luck also helps.

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

Lluis: I like to garden (actually, I can spend hours gardening), to bike, and, increasingly, to run. These three things really empty my mind and recharge my batteries. Also, I do need to go at least once per year to Mallorca (where I was born). Having lived there until I was 20 gave me a handicap for life: my need for sun and sea (and I live in Paris…). There’s nothing that relaxes me more than getting into the turquoise Mediterranean water and swimming!

I also love art exhibitions, almost exclusively modern art, and pop if possible! I spent last summer in NYC on a mini-sabbatical at Rockefeller University, and I really enjoyed the exhibitions there!

I also like to read. I can compulsively read historical biographies. When I enjoy somebody’s life, I can read 30 books about them even if most of them say the same thing. A recent example is the life of Princess Marie Bonaparte – a psychoanalyst and close friend of Sigmund Freud, whom she helped escape from Nazi Germany. I also love reading about contemporary politics: one of my preferred topics is the so-called “Spanish transition,” the period starting 1975-1980 when Spain transitioned from being under Franco’s non-democratic regime to being the modern, open-minded country that is today. Obviously, I like books about evolution, but then, that is more work-related again…

Inside AJHG: A Chat with Susan Slaugenhaupt

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 Sue Slaugenhaupt to discuss her paper, “ELP1 Splicing Correction Reverses Proprioceptive Sensory Loss in Familial Dysautonomia”.

20190423_Slaughenhaupt-Lab

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

Sue: When I arrived at Massachusetts General Hospital as a postdoctoral fellow in 1991, one of the projects in Jim Gusella’s lab was focused on mapping the gene for familial dysautonomia (FD). Given my background in gene mapping, I became involved in the project and once we mapped the gene, I took over the project aimed at identifying the mutation. Once we cloned the gene and discovered that it was a mRNA splicing defect, I became fascinated by the idea of modifying splicing as a route to therapy, and my lab has worked on this ever since. I have known many FD patients and their families for over 25 years, and our work is driven by the desire to develop a disease modifying therapy for this devastating disease.

AJHG: What about this paper most excites you? 

Sue: Developing a mouse model for FD was a huge challenge since the disease is caused by a tissue-specific reduction of ELP1 protein. In 2016, we succeeded in generating a phenotypic mouse model and this paper describes the first trial of a potential therapy in our mouse. I am very excited that our treatment was able to increase the amount of ELP1 protein in the peripheral nervous system and, most importantly, rescue two of the most debilitating aspects of the disease, gait ataxia and kyphosis.

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

Sue: There are many efforts underway to generate therapies that target mRNA splicing, including small molecules, antisense oligonucleotides, and exon-specific U1 snRNAs. A significant fraction of human genetic disease mutations impact mRNA splicing, so this is an exciting time. These therapies are targeted at the molecular mechanism of disease, not at symptoms, and we are likely to see new treatments for many previously untreatable genetic diseases over the next several years.

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

Sue: Find a good mentor. One who cares more about your future and your career than their own. Look outside your own lab, and fight against the tide that keeps you locked in an unproductive situation too long.

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

Sue: I’m moving to a condo overlooking the beach next month and I can’t wait!
