Gene: DMPKComment on mode of inheritance: Lack of phenotypic relevance for SNVs - nucleotide repeat expansion mechanismCreated: 9 Nov 2021, 3:24 p.m. | Last Modified: 9 Nov 2021, 3:24 p.m.
Panel Version: 1.16
Comment on mode of pathogenicity: CTG repeat expansion in the 3' UTR region. Information in OMIM indicates that unaffected individuals have between 5 and 37 copies, whereas dystrophia myotonica 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.Created: 19 Oct 2016, 8:56 a.m.
Comment on list classification: Demoted from green to red due to the disease-causing mechanism - myotonic dystrophy is cause by a CTG repeat expansion in the 3' UTR region of the DMPK gene, rather than loss of function variants within the gene. Evidence level for this is high - it is a confirmed DD gene for DYSTROPHIA MYOTONICA TYPE 1.
