About Myotonic Dystrophy Type 1 (DM1) Myotonic dystrophy is an inherited condition broadly characterized by progressive muscle weakness and myotonia (when muscles are unable to relax following contraction), central nervous system defects, cardiac issues, and endocrine dysfunction. The genetic defect in myotonic dystrophy is an expanded, noncoding CTG codon repeat at the 3′ end of one of two genes. Myotonic Dystrophy type 1(DM1), also called Steinert syndrome, is a multisystemic disorder transmitted in an autosomal dominant manner, characterized by myotonia. 2021, Muscular Dystrophy Association Inc.
