Breast cancer genome-wide association studies (GWAS) have identified over 200 independent genome-wide significant susceptibility markers. However, most studies have focused on one or two ancestral groups. We examined breast cancer genetic architecture using GWAS summary statistics from African (AFR), East Asian (EAS), European (EUR) and Hispanic/Latina (H/L) samples, totaling 159,297 cases and 212,102 controls, comprising the largest multi-ancestry study of breast cancer to date.

A major hurdle in understanding the molecular changes responsible for metazoan diversity is the characterization of cis-regulatory elements (CREs) for gene regulatory networks (GRNs). CRE changes are suspected to be commonplace in trait evolution, since such changes circumvent deleterious effects of pleiotropy. A growing list of genes, though, are known to be regulated by redundant CREs.

Psoriasis vulgaris (PsV) is an immune-mediated inflammatory skin disorder with complex genetic architecture. Most genome-wide association studies (GWASs) of PsV have been limited to analyzing common single-nucleotide variants in Europeans, lacking diversity in the variant spectrum and ancestral background. To investigate the contribution of rare variants (RVs) and structural variants (SVs), we perform a whole-genome sequencing study involving 1,415 PsV cases and 3,968 controls in Japanese.

Previous genomic analyses revealed that massive transposable element (TE) proliferation represents a convergent genomic feature of ECM fungi, including Tuberaceae. Repetitive sequences constitute a principal driver of genome evolution shaping its architecture and regulatory networks.

The evolution of sexual dimorphism (the difference in average trait values between females and males, SD), is often thought to be constrained by shared genetic architecture between the sexes. Indeed, it is commonly expected that SD should negatively correlate with the intersex correlation (the genetic correlation between effects of segregating variants in females and males, r fm), either because (1) traits with ancestrally low r fm are less constrained in their ability to respond to sex-specific selection and thus evolve to be more dimorphic, or because (2) sex-specific selection, driving sexual dimorphism evolution, also acts to reduce r fm. Despite the intuitive appeal and prominence of these ideas, their generality and the conditions in which they hold remain unclear.
