Jennifer Troyer appointed incoming director of the NHGRI Division of Extramural Operations
To keep NHGRI’s website, genome.gov, at the cutting edge, the NHGRI Office of Communications recently implemented some new features that take advantage of the latest advances in web design and technology. These changes are intended to improve search engine optimization to increase site traffic and to enhance user experience, so that visitors can more efficiently find resources of interest. The enhanced genome.gov site has a more interactive and simplified layout, a larger search bar, a more prominent navigation bar, and an expanded footer featuring content about training, funding, careers, and special initiatives. Hopefully, visitors will find the new ‘look and feel’ of genome.gov to be refreshing during these hot summer months.
Also, the Inter-Society Coordinating Committee for Practitioner Education in Genomics (ISCC-PEG) Scholars Program applications are due on September 1, 2023. The ISCC-PEG is a collaborative group aimed at improving healthcare provider genomics education. The Scholars Program provides exposure to the broader genomics community and experts in the field, with the opportunity to work on a genetics/genomics-related education project under the mentorship of an ISCC-PEG member. Selected candidates will be notified by mid-October 2023.
All the best,

Polygenic scoring accuracy varies across the genetic ancestry continuum
Ding et al.
Nature. 2023 Jun;618(7966):774-781. PMC10284707
Although some human traits and diseases are caused by genomic variants in a single gene, it is often the case that variants in many genes contribute to the risk of developing traits and diseases. Scientists and clinicians use tools called polygenic scores to calculate such a risk by combining information about all the genomic variants associated with a disease. Many examples of using polygenic scores have been reported that involve data generated from individuals of European ancestry, but such studies are limited in their applicability in groups of different ancestries. In this article, researchers from the University of California show how the accuracy of polygenic scores decreases when applied to more ancestrally diverse groups and when done at a group level rather than individual level. These findings highlight how polygenic scores poorly translate between groups but, perhaps even more importantly, how they need to have a more personalized approach. Low accuracy of polygenic scores could potentially lead to health disparities.
