Is TRAF3IP2 p.Pro37Ser (c.109C>T) pathogenic?

TRAF3IP2 p.Pro37Ser (c.109C>T) is classified Uncertain significance in TRAF3IP2 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2022-10-18). AlphaMissense: likely benign (0.1037); Ultra-rare (popmax 0.0167%, amr); Associated with candidiasis, familial, 8.

What condition is associated with TRAF3IP2 p.Pro37Ser (c.109C>T)?

TRAF3IP2 p.Pro37Ser (c.109C>T) is associated with candidiasis, familial, 8 (ClinVar).

How common is TRAF3IP2 p.Pro37Ser (c.109C>T) in the general population?

TRAF3IP2 p.Pro37Ser (c.109C>T) is ultra-rare (popmax 0.0167%, amr) (gnomAD).

How is Chronic mucocutaneous candidiasis inherited?

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

What do computational predictors say about TRAF3IP2 p.Pro37Ser (c.109C>T)?

AlphaMissense predicts likely benign (score 0.1037) — 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.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM P46S vs ClinVar P37S) — verify the residue.

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.
