Why it matters in GWAS

GWAS hits are interpreted through gene structure, regulation, and variant consequence; molecular vocabulary connects association statistics to mechanism.

Example usage

"The sentinel variant sits near a CpG island with differential methylation across case and control samples."

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.
