Very rare cause but can be an additional feature along with myopathy see: Gatayama Pediatrics 2013;131:e1e5 - 1 case study of nemaline myopathy and DCM. Reza 2018 (Circ Genom Precis Med. 2018;11:e002243. DOI: 10.1161/CIRCGEN.118.002243) - large family with a proband, sibling and cousin all affected with DCM and a ACTA1 variant which has no GnomAD freq, there are three obligate carriers of the variant who are affected between these relatives, suggesting high penetrance disease causing variant, adult onset in this family reported. Tadokoro 2018( Journal of the Neurological Sciences 393 (2018) 142144: 1) presented a case series of 7 patients presenting with myopathy: 2 had DCM 5 had HCM, all childhood onset.

Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
On the Inherited Cardiac Condition Genes panel for Dilated cardiomyopathy reported in: Development of a Comprehensive Sequencing Assay for Inherited Cardiac Condition Genes, Pua et al, Journal of Cardiovascular Translational Research, online Feb 2016 (doi:10.1007/s12265-016-9673-5). The panel contains disease-causing, putatively pathogenic, research and phenocopy genes, and it is unclear from the publication whether this gene falls into the disease-causing category. No. of mutations indicated in supplemental table = 1.
