Is BIN1 p.Pro431Ser (c.1291C>T) pathogenic?

BIN1 p.Pro431Ser (c.1291C>T) is classified Uncertain significance in BIN1 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-03-13). AlphaMissense: likely benign (0.0724); Absent from gnomAD v4.1; Associated with myopathy, centronuclear, 2.

What condition is associated with BIN1 p.Pro431Ser (c.1291C>T)?

BIN1 p.Pro431Ser (c.1291C>T) is associated with myopathy, centronuclear, 2 (ClinVar).

How common is BIN1 p.Pro431Ser (c.1291C>T) in the general population?

BIN1 p.Pro431Ser (c.1291C>T) is absent from gnomAD v4.1 (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.Pro431Ser (c.1291C>T)?

AlphaMissense predicts likely benign (score 0.0724) — 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.

No allele count reported in gnomAD v4.1 (AN 1,586,144). This is missing data, not an absence: the variant may or may not be present in gnomAD. Rarity (ACMG PM2) and BA1/BS1 cannot be assessed for it.
