gnomAD v4.1
Common
common (popmax 19.9%, sas) — too common for a highly-penetrant pathogenic allele

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
