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. |
| Remarks |
Clinical status unknown; droopy eyelids; stiff when cold; cardiac arrhythmia; donor subject has one normal CTG repeat allele and one allele with a CTG repeat size of 66 in the DMPK gene; affected daughter is GM04608; two affected granddaughters are GM04601 and GM06077; EMG exam was normal; see GM06076 fibroblast |
