Is FLNC p.Asp2093= (c.6279C>T) pathogenic?

FLNC p.Asp2093= (c.6279C>T) is classified Likely benign in FLNC (ClinVar, Multiple submitters, 4 submitters; last evaluated 2025-10-26). Ultra-rare (popmax 0.0401%, eas); Associated with myofibrillar myopathy 5.

What condition is associated with FLNC p.Asp2093= (c.6279C>T)?

FLNC p.Asp2093= (c.6279C>T) is associated with myofibrillar myopathy 5, distal myopathy with posterior leg and anterior hand involvement, hypertrophic cardiomyopathy 26 (ClinVar).

How common is FLNC p.Asp2093= (c.6279C>T) in the general population?

FLNC p.Asp2093= (c.6279C>T) is ultra-rare (popmax 0.0401%, eas) (gnomAD).

How is Muscle filaminopathy inherited?

Typically Autosomal dominant (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.
