Is BIN1 p.Ala481Val (c.1442C>T) pathogenic?

BIN1 p.Ala481Val (c.1442C>T) is classified Uncertain significance in BIN1 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-10-16). AlphaMissense: likely benign (0.0786); Ultra-rare (popmax 0.0165%, mid); Associated with myopathy, centronuclear, 2.

What condition is associated with BIN1 p.Ala481Val (c.1442C>T)?

BIN1 p.Ala481Val (c.1442C>T) is associated with myopathy, centronuclear, 2 (ClinVar).

How common is BIN1 p.Ala481Val (c.1442C>T) in the general population?

BIN1 p.Ala481Val (c.1442C>T) is ultra-rare (popmax 0.0165%, mid) (gnomAD).

How is Autosomal recessive centronuclear myopathy inherited?

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

What do computational predictors say about BIN1 p.Ala481Val (c.1442C>T)?

AlphaMissense predicts likely benign (score 0.0786) — 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.
