Is DRD3 p.Thr14Ile (c.41C>T) pathogenic?

DRD3 p.Thr14Ile (c.41C>T) is classified Uncertain significance in DRD3 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-07-14). AlphaMissense: likely benign (0.1934); Very rare (popmax 0.000958%, nfe).

How common is DRD3 p.Thr14Ile (c.41C>T) in the general population?

DRD3 p.Thr14Ile (c.41C>T) is very rare (popmax 0.000958%, nfe) (gnomAD).

What do computational predictors say about DRD3 p.Thr14Ile (c.41C>T)?

AlphaMissense predicts likely benign (score 0.1934) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.1934	likely benign
REVEL	0.315	indeterminate
SaProt	LLR -9.99	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no call.

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.
