What condition is associated with BIN1 p.Ser298= (c.894G>A)?

BIN1 p.Ser298= (c.894G>A) is associated with myopathy, centronuclear, 2 (ClinVar).

How is Autosomal recessive centronuclear myopathy inherited?

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

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.
