Description

The ACTA1 c.1008G>C variant is predicted to result in the amino acid substitution p.Glu336Asp. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Two other missense variants at the same amino acid position have been reported in patients with autosomal dominant ACTA1-related myopathy, and one of the two segregated with the phenotype within a three generation pedigree (Kaindl et al. 2004. PubMed ID: 15520409; Laing et al. 2009. PubMed ID: 19562689). This variant is interpreted as likely pathogenic.
