Is FLNC p.Gln94= (c.282A>G) pathogenic?

FLNC p.Gln94= (c.282A>G) is classified Benign/Likely benign in FLNC (ClinVar, Multiple submitters, 3 submitters; last evaluated 2025-12-21). Ultra-rare (popmax 0.0133%, amr); Associated with myofibrillar myopathy 5.

What condition is associated with FLNC p.Gln94= (c.282A>G)?

FLNC p.Gln94= (c.282A>G) is associated with myofibrillar myopathy 5, distal myopathy with posterior leg and anterior hand involvement, hypertrophic cardiomyopathy 26 (ClinVar).

How common is FLNC p.Gln94= (c.282A>G) in the general population?

FLNC p.Gln94= (c.282A>G) is ultra-rare (popmax 0.0133%, amr) (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.
