ANO5 p.Ser648=

Q: What condition is associated with ANO5 p.Ser648= (c.1944T>C)?

ANO5 p.Ser648= (c.1944T>C) is associated with autosomal recessive limb-girdle muscular dystrophy type 2L, gnathodiaphyseal dysplasia (ClinVar).

Q: How is Anoctamin-5-related limb-girdle muscular dystrophy R12 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.
