"WebDM1. The microsatellite expansion responsible for DM1 is of cytosine-thymine-guanine (CTG) triplet repeats, termed trinucleotide repeat expansion and classifying DM1 as a one of several trinucleotide repeat disorders. This expansion occurs at the end of the DMPK gene, in the 3' untranslated region. DMPK is located on the long arm of chromosome 19. " - Dm1 repeat expansion

WebThe etiology of DM1 lies in the repeat length expansion of the CTG trinucleotide in the 3′ untranslated region of the Dystrophica Myotonica Protein Kinase (DMPK) gene on chromosome 19q.13.3 [5,12,13,14]. The transcription of these repeat lengths from this CTG tri-nucleotide into messenger RNA GUC tri-nucleotides results in the accumulation of ... WebDM1 results from a mutation in the DMPK gene that encodes the myotonic dystrophy protein kinase. The mutation is termed a repeat expansion mutation because it is characterized by long repeats of the trinucleotide CUG in the DMPK pre-mRNA. Whereas most healthy people have less than 40 repeats, DM1 patients can have hundreds of repeats.
