Why it matters in GWAS

VNTRs can influence phenotype through dosage or regulatory effects, yet they are often poorly captured by SNP arrays and standard imputation pipelines.

Example usage

"A VNTR near the promoter was considered a candidate driver of the association signal."

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.
