Is DMRTA2 p.Pro301Ser (c.901C>T) pathogenic?

DMRTA2 p.Pro301Ser (c.901C>T) is classified Uncertain significance in DMRTA2 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-10-28). AlphaMissense: likely benign (0.0766); Very rare (popmax 0.00204%, nfe).

How common is DMRTA2 p.Pro301Ser (c.901C>T) in the general population?

DMRTA2 p.Pro301Ser (c.901C>T) is very rare (popmax 0.00204%, nfe) (gnomAD).

What do computational predictors say about DMRTA2 p.Pro301Ser (c.901C>T)?

AlphaMissense predicts likely benign (score 0.0766) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0766	likely benign
REVEL	0.073	moderately benign-leaning
SaProt	LLR -7.32	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.

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.
