Why it matters in GWAS

dbSNP rsIDs are the common language for reporting, matching, and integrating variants across GWAS datasets, summary statistics, and downstream annotation tools.

Example usage

"We mapped all lead variants to dbSNP rsIDs before meta-analysis and annotation."

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.
