1/13 In a new preprint, we (with
@xliaoyi.bsky.social
‬ in the ‪@arbelharpak.bsky.social‬ lab) find that expression from the “inactivated” X (Xi) is consequential for both female-male differences in gene expression and variation among females in disease and physiology:

Escape from X inactivation drives sex differences and female trait variation
X chromosome inactivation (XCI) partially balances gene dosage between sexes, yet expression from the inactive X (Xi) is variable across genes. In this study, we investigate whether gene-level Xi expr...

Led by Brieuc Lehmann, we have a paper on relatedness and ARG! Closely related to my PROBGEN talk on Friday.

Think of a polygenic score you care about. Are direct genetic effects driving variation among people in this predictor? Or perhaps other, confounding factors? We at the

A Litmus Test for Confounding in Polygenic Scores
Polygenic scores (PGSs) are being rapidly adopted for trait prediction in the clinic and beyond. PGSs are often thought of as capturing the direct genetic effect of one's genotype on their phenotype. ...

No evidence for sex-differential transcriptomes driving genome-wide sex-differential natural selection
We assess the evidence for a genome-wide relationship between sex differences in gene expression and sex differences in natural selection. We develop an improved model for testing this association but...
