Myotonic Dystrophy (DM) is a genetic disorder that affects muscle function and other systems of the body. There are two main types: 1. Myotonic Dystrophy Type 1 (DM1): Also known as Steinert's disease, DM1 is caused by a mutation in the "DMPK gene" (Dystrophia Myotonica Protein Kinase). The mutation involves an expansion of CTG trinucleotide repeats in this gene, leading to symptoms such as prolonged muscle contractions (myotonia), muscle weakness, …

1. DM1 (Myotonic Dystrophy Type 1): DM1 is a genetic disorder characterized by progressive muscle wasting and weakness. It is an autosomal dominant condition caused by an expanded CTG trinucleotide repeat in the DMPK gene. Individuals with DM1 may experience myotonia (prolonged muscle contraction), weakness in facial and distal muscles, cardiac issues, and intellectual impairment.   2. DM2 (Myotonic Dystrophy Type 2): Similar to DM1, DM2 is an autosomal dominant …
