Computational evidence
| Protein change | ||
| AlphaMissense | 0.1343 | likely benign |
|---|---|---|
| REVEL | 0.077 | moderately benign-leaning |
| SaProt | LLR -5.07 | tolerated |
| ⇒ AlphaMissense, REVEL and SaProt all call this tolerated. | ||
| Splicing | ||
| SpliceAI | <0.2 | all four deltas below 0.2 · C>A here scores Δ0.33 · evaluated, not missing |

| Conservation | phyloP 1.9 | GERP -2.8, phastCons 1 |
| Regional constraint | o/e 0.97 | unconstrained · MANE · 12 kb · p 0.71 · regional, not allelic |
| Overall | ||
| CADD | 19.91 | PHRED · no single calibrated threshold — expert panels disagree |
ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — 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 |
|---|---|---|
| African / African-Americangrpmax | 0.00674% | 14,844 |
| Admixed American | 0.00383% | 26,141 |
| European (non-Finnish) | 0.00243% | 41,163 |
| Remaining individualsnot grpmax-eligible | 0.00165% | 60,636 |
| South Asian | 0.00118% | 85,002 |
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.
