Is TRIM32 p.Pro329Arg (c.986C>G) pathogenic?

TRIM32 p.Pro329Arg (c.986C>G) is classified Uncertain significance in TRIM32 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-07-07). AlphaMissense: likely benign (0.0862); Very rare (popmax 0.00133%, afr); Associated with autosomal recessive limb-girdle muscular dystrophy type 2H.

How common is TRIM32 p.Pro329Arg (c.986C>G) in the general population?

TRIM32 p.Pro329Arg (c.986C>G) is very rare (popmax 0.00133%, afr) (gnomAD).

How is TRIM32-related limb-girdle muscular dystrophy R8 inherited?

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

What do computational predictors say about TRIM32 p.Pro329Arg (c.986C>G)?

AlphaMissense predicts likely benign (score 0.0862) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change

REVEL	0.389	indeterminate
SaProt	LLR -6.60	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.
