Population frequency
| Ancestry group | Frequency | 1 in |
|---|---|---|
| Remaining individualsnot grpmax-eligible | 0.0016% | 62,510 |
| European (non-Finnish)grpmax | 8.47e-05% | 1,180,026 |
Remaining individuals shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.
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.
