Happy to highlight new findings by Vanesa Getseva and Lin Poyraz about the sources of variation in germline mutation rates among humans: www.biorxiv.org/content/10.6... Joint work with Anastasia Stolyarova and @ipsitaagarwal.bsky.social. 1/n

A sibling study of variation in parental mutation rates

People are born with variable numbers of de novo germline mutations (DNMs), depending primarily on the ages of their parents. To explore additional causes, we developed an approach to call DNMs from nucleotide differences between siblings in genomic regions inherited identical by descent from both parents. Applying it to whole genome sequences from 28,985 sibling pairs of diverse genetic ancestries present in the UK Biobank and All of Us datasets, as well as 2,330 trios, we identified >800K autosomal DNMs and characterized mutation phenotypes in 27,645 sets of parents. We found subtle shifts in the mutation spectrum but no differences in total DNM rates among genetic ancestry groups, or between smokers and non-smokers. Testing for associations between parental mutation phenotypes and their burden of loss-of-function and deleterious missense variants in a set of 180 DNA repair and maintenance genes, we discovered that disruptions in REV1 and LIG1 increase germline mutation rates, and thus that rare mutator alleles segregate in population cohorts. ### Competing Interest Statement The authors have declared no competing interest.

Our work on the generalizability of polygenic scores (PGS) from the @arbelharpak.bsky.social Lab is now officially out! We examine the accuracy of PGS predictions at the individual level. We make 3 observations that expose gaps in our understanding of PGS “portability.” rdcu.be/e0LAr (1/27)

SAVE THE DATE: the yearly NY Population Genetics meeting will be back on March 9 2026, generously hosted by the @simonsfoundation.org. Details to follow. Please RT.

GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult. Our latest work on causal models for this is out yesterday: www.nature.com/articles/s41... A short🧵:

Causal modelling of gene effects from regulators to programs to traits - Nature

Approaches combining genetic association and Perturb-seq data that link genetic variants to functional programs to traits are described.

Delighted that our paper about the distribution of genomic spans of clades/edges in genealogies (ARGs), and using this for detecting inversions and other SVs (and other phenomena that cause local disruption of recombination) is out in MBE academic.oup.com/mbe/article/... (1/n)

Abstract. Recent breakthroughs have enabled the accurate inference of large-scale genealogies. Through modelling the impact of recombination on the correla

Our paper about how ancestral recombination graphs can be used to detect "phantom" genetic interaction signals (that arise due to the genealogy, rather than "real" epistasis) is out in Genetics! Nice thread here by @linoafferreira.bsky.social academic.oup.com/genetics/adv...

Phantom epistasis through the lens of genealogies

Abstract. Phantom epistasis arises when, in the course of testing for gene-by-gene interactions, the omission of a causal variant with a purely additive ef
