Is FLNC p.Ser2539Pro (c.7615T>C) pathogenic?

FLNC p.Ser2539Pro (c.7615T>C) is classified Uncertain significance in FLNC (ClinVar, Single submitter, 1 submitter; last evaluated 2026-01-21). AlphaMissense: likely pathogenic (0.9732); Absent from gnomAD v4.1; Associated with myofibrillar myopathy 5.

What condition is associated with FLNC p.Ser2539Pro (c.7615T>C)?

FLNC p.Ser2539Pro (c.7615T>C) is associated with myofibrillar myopathy 5, distal myopathy with posterior leg and anterior hand involvement, hypertrophic cardiomyopathy 26 (ClinVar).

How common is FLNC p.Ser2539Pro (c.7615T>C) in the general population?

FLNC p.Ser2539Pro (c.7615T>C) is absent from gnomAD v4.1 (gnomAD).

How is Muscle filaminopathy inherited?

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

What do computational predictors say about FLNC p.Ser2539Pro (c.7615T>C)?

AlphaMissense predicts likely pathogenic (score 0.9732) — an in-silico prediction, not a clinical call.
