What condition is associated with BIN1 p.Arg581His (c.1742G>A)?

BIN1 p.Arg581His (c.1742G>A) is associated with myopathy, centronuclear, 2 (ClinVar).

How common is BIN1 p.Arg581His (c.1742G>A) in the general population?

BIN1 p.Arg581His (c.1742G>A) is very rare (popmax 0.00333%, amr) (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.Arg581His (c.1742G>A)?

AlphaMissense predicts likely benign (score 0.1411) — an in-silico prediction, not a clinical call.

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.
