Why it matters in GWAS

Population structure, demographic history, and mating patterns affect allele frequencies, LD, relatedness, and cross-cohort portability—central to GWAS design and interpretation.

Example usage

"The consortium reported American-ancestry summary statistics separately, then evaluated PRS portability across sites with different recruitment histories."

Related-term network

Click any node to open that term page.

Node order. The current term is first. Next come every page linked from Related terms, in the same top-to-bottom order as that list. Then new terms appear in two-hop layers: for each of those direct neighbors (in that same order), their related terms are appended if not already listed. A third pass does the same for two-hop nodes. The walk stops when a fixed maximum number of nodes is reached.
