Gene DMPK
Chromosomal Location 19q13.2-q13.3
Allelic Variant 1 605377.0001; MYOTONIC DYSTROPHY
Identified Mutation (CTG)n EXPANSION; The consistent genetic defect associated with myotonic dystrophy is an amplified trinucleotide CTG repeat in the 3-prime untranslated region of the serine-threonine kinase gene DMK on 19q. Unaffected individuals have between 5 and 27 copies. DM patients who are minimally affected have at least 50 repeats, while more severely affected patients have expansion of the repeat-containing segment up to several kilobases.
