ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification
AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
Population frequency
| Ancestry group | Frequency | 1 in |
|---|---|---|
| Ashkenazi Jewishnot grpmax-eligible | 0.00338% | 29,602 |
| South Asiangrpmax | 0.0022% | 45,542 |
| Admixed American | 0.00167% | 60,008 |
| African / African-American | 0.00133% | 74,934 |
| European (non-Finnish) | 0.000593% | 168,572 |
Ashkenazi Jewish 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.
