Variable prediction accuracy of polygenic scores within an ancestry group

H Mostafavi, A Harpak, I Agarwal, D Conley… - elife, 2020 - elifesciences.org
Fields as diverse as human genetics and sociology are increasingly using polygenic scores
based on genome-wide association studies (GWAS) for phenotypic prediction. However, …

Reduced signal for polygenic adaptation of height in UK Biobank

JJ Berg, A Harpak, N Sinnott-Armstrong… - Elife, 2019 - elifesciences.org
10.7554/eLife.39725.001 Several recent papers have reported strong signals of selection
on European polygenic height scores. These analyses used height effect estimates from the …

[HTML][HTML] The evolution of group differences in changing environments

A Harpak, M Przeworski - PLoS Biology, 2021 - journals.plos.org
The selection pressures that have shaped the evolution of complex traits in humans remain
largely unknown, and in some contexts highly contentious, perhaps above all where they …

Between-region genetic divergence reflects the mode and tempo of tumor evolution

R Sun, Z Hu, A Sottoriva, TA Graham, A Harpak, Z Ma… - Nature …, 2017 - nature.com
Given the implications of tumor dynamics for precision medicine, there is a need to
systematically characterize the mode of evolution across diverse solid tumor types. In particular, …

[HTML][HTML] Mutation rate variation is a primary determinant of the distribution of allele frequencies in humans

A Harpak, A Bhaskar, JK Pritchard - PLoS genetics, 2016 - journals.plos.org
The site frequency spectrum (SFS) has long been used to study demographic history and
natural selection. Here, we extend this summary by examining the SFS conditional on the …

Thousands of novel translated open reading frames in humans inferred by ribosome footprint profiling

A Raj, SH Wang, H Shim, A Harpak, YI Li… - elife, 2016 - elifesciences.org
10.7554/eLife.13328.001 Accurate annotation of protein coding regions is essential for
understanding how genetic information is translated into function. We describe riboHMM, a new …

Evidence for weak selective constraint on human gene expression

EC Glassberg, Z Gao, A Harpak, X Lan, JK Pritchard - Genetics, 2019 - academic.oup.com
Variation in human complex traits is connected to variation in gene expression, and selection
on complex traits can be reflected in selection on gene expression. Here, Glassberg and …

[PDF][PDF] Amplification is the primary mode of gene-by-sex interaction in complex human traits

…, MJ Ming, JM Cole, MD Edge, M Kirkpatrick, A Harpak - Cell Genomics, 2023 - cell.com
Sex differences in complex traits are suspected to be in part due to widespread gene-by-sex
interactions (GxSex), but empirical evidence has been elusive. Here, we infer the mixture of …

Frequent nonallelic gene conversion on the human lineage and its effect on the divergence of gene duplicates

A Harpak, X Lan, Z Gao… - Proceedings of the …, 2017 - National Acad Sciences
Gene conversion is the copying of a genetic sequence from a “donor” region to an “acceptor.”
In nonallelic gene conversion (NAGC), the donor and the acceptor are at distinct genetic …

[PDF][PDF] Concerted evolution reveals co-adapted amino acid substitutions in Na+ K+-ATPase of frogs that prey on toxic toads

S Mohammadi, L Yang, A Harpak, S Herrera-Álvarez… - Current Biology, 2021 - cell.com
Although gene duplication is an important source of evolutionary innovation, the functional
divergence of duplicates can be opposed by ongoing gene conversion between them. Here, …
