Why it matters in GWAS

These concepts shape how we expect variants to act (penetrance, heterogeneity, threshold models) and how GWAS signals should be interpreted alongside family-based evidence.

Example usage

"Downstream interpretation uses Phenotypic heterogeneity to connect statistical signals with biological context."

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.
