Genes linked to Myopathy, distal, 6, adult-onset, autosomal dominant
ACTN2: Alpha-actinin-2
It crosslinks actin at the sarcomeric Z-disc and organizes mechanical and signaling complexes in cardiac and skeletal muscle. Pathogenic variants can cause hypertrophic, dilated, or other inherited cardiomyopathies and occasional skeletal-muscle phenotypes.
1 disease-causing and 50 uncertain variants in ACTN2 are linked to Myopathy, distal, 6, adult-onset, autosomal dominant.

None of the uncertain variants currently reaches the likely-pathogenic range on computable evidence alone.
About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
