Why it matters in GWAS

Minor-allele labeling is frequency-based and cohort-specific, so it can change across ancestries and studies. It should not be assumed to match effect, risk, alternative, or derived labels.

Example usage

"Quality control excluded variants with very low minor allele count before association testing."

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.
