How common is TYRO3 p.Val77Leu (c.229G>T) in the general population?

TYRO3 p.Val77Leu (c.229G>T) is very rare (popmax 8.47e-05%, nfe) (gnomAD).

What do computational predictors say about TYRO3 p.Val77Leu (c.229G>T)?

AlphaMissense predicts likely benign (score 0.0818) — an in-silico prediction, not a clinical call.

REVEL	0.251	benign-leaning
SaProt	LLR -6.07	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.
