Is PRLR p.Val237Met (c.709G>A) pathogenic?

PRLR p.Val237Met (c.709G>A) is classified Uncertain significance in PRLR (ClinVar, Single submitter, 1 submitter; last evaluated 2025-05-30). AlphaMissense: likely benign (0.0918); Ultra-rare (popmax 0.0401%, eas).

How common is PRLR p.Val237Met (c.709G>A) in the general population?

PRLR p.Val237Met (c.709G>A) is ultra-rare (popmax 0.0401%, eas) (gnomAD).

What do computational predictors say about PRLR p.Val237Met (c.709G>A)?

AlphaMissense predicts likely benign (score 0.0918) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.0918	likely benign
REVEL	0.068	moderately benign-leaning
SaProt	LLR -7.76	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know

Regional constraint	o/e 0.95	unconstrained · MANE · 5,076 bp · p 0.31 · regional, not allelic
Overall
CADD	7.424	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.

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.
