  1. Mutations in the four human actinin proteins that are associated with diseases or phenotypic traits are listed.
  2. The protein domain and subdomain (e.g. ABD, CH1) in which each mutation occurs is indicated in the third column. A forward slash (e.g. Rod/CaM) indicates a mutation within a region linking the two domains indicated. The asterisk indicates that these are equivalent Arg residues in a sequence alignment of actinin-1 and −2. A multiple sequence alignment highlighting the postions of disease-causing mutations is provided as additional information [Additional file 1].
  3. Abbreviations: IVF Idiopathic ventricular fibrillation, LVNC Left ventricular non-compaction, SUD Sudden unexplained death, CMTP Congenital macrothrombocytopenia, HCM Hypertrophic cardiomyopathy, DCM Dilated cardiomyopathy, FSGS Focal segmental glomerulosclerosis
