What condition is associated with VCL p.Arg669= (c.2005C>A)?

VCL p.Arg669= (c.2005C>A) is associated with dilated cardiomyopathy 1W (ClinVar).

How common is VCL p.Arg669= (c.2005C>A) in the general population?

VCL p.Arg669= (c.2005C>A) is very rare (popmax 8.48e-05%, nfe) (gnomAD).

How is Familial isolated dilated cardiomyopathy inherited?

Typically Autosomal dominant, 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.
