Anti-microRNAs for the treatment of myotonic dystrophy. Myotonic dystrophy type 1 (DM1) is a rare, neuromuscular disease that affects multiple organ systems, and is characterized primarily by myotonia and progressive muscle wasting and weakness. DM 1 is also called Steinert’s disease. Inclusion on this list is not an endorsement by GARD. Background: Myotonia is an early, prominent symptom in DM1 and contributes to decreased dexterity, gait instability, difficulty with speech/swallowing, and muscle pain. Both the types are caused by genetic autosomal abnormality, which means that the responsible gene mutation abnormality in due to one copy that can be able to cause the disorder. DM is divided into two types: type 1 affects a gene called DMPK on chromosome 19, and type 2 affects a gene on chromosome 3 called ZNF9. We remove all identifying information when posting a question to protect your privacy.

Myotonic Dystrophy or dystrophia myotonica (DM) is a genetic disease characterized by progressive muscle degeneration. DM1 is caused by a change or alteration in the myotonic dystrophy protein kinase (DMPK) gene.DM2 is caused by a change or alteration in the nucleic acid-binding protein (CNBP) gene; this gene is also called the ZNF9 gene.Genes provide instructions for creating … Myotonic muscular dystrophy is of two types – Type 1 and Type 2. 19,20 Myotonic dystrophy type 1 results from a defect in the DMPK gene that codes for myotonic dystrophy protein kinase, and myotonic dystrophy type 2 is due to a defect in the ZNF9 gene (zinc finger protein 9, a cellular retroviral nucleic acid binding protein). 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) is a life-threatening and chronically debilitating neuromuscular disease caused by the expansion of a CTG trinucleotide repeat in the 3′ UTR of the DMPK gene. 2021, Muscular Dystrophy Association Inc.
