Is STAT5B p.Val696Ile (c.2086G>A) pathogenic?

STAT5B p.Val696Ile (c.2086G>A) is classified Uncertain significance in STAT5B (ClinVar, Single submitter, 1 submitter; last evaluated 2024-02-27). AlphaMissense: likely benign (0.087); Very rare (popmax 0.00133%, afr); Associated with growth hormone insensitivity with immune dysregulation 1, autosomal recessive.

What condition is associated with STAT5B p.Val696Ile (c.2086G>A)?

STAT5B p.Val696Ile (c.2086G>A) is associated with growth hormone insensitivity with immune dysregulation 1, autosomal recessive (ClinVar).

How common is STAT5B p.Val696Ile (c.2086G>A) in the general population?

STAT5B p.Val696Ile (c.2086G>A) is very rare (popmax 0.00133%, afr) (gnomAD).

How is Laron syndrome with immunodeficiency inherited?

Typically Autosomal dominant, Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about STAT5B p.Val696Ile (c.2086G>A)?

AlphaMissense predicts likely benign (score 0.087) — an in-silico prediction, not a clinical 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.
