Genes linked to Cardiomyopathy, familial hypertrophic, 23, with or without ventricular noncompaction
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.
2 disease-causing and 0 uncertain variants in ACTN2 are linked to Cardiomyopathy, familial hypertrophic, 23, with or without ventricular noncompaction.
Known disease-causing variants in Cardiomyopathy, familial hypertrophic, 23, with or without ventricular noncompaction

|---|---|---|---|
| ACTN2 E628G | 628 | Disease-causing | |

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.
