Sporadic myopathy, myoclonus, leukoencephalopathy, neurosensory deafness, hypertrophic cardiomyopathy and insulin resistance associated with the mitochondrial 8306 T>C MTTK mutation.

Abstract excerpt

We report a new T8306C transition in the D-stem of the MTTK gene of a 67-year-old man who manifested severe adult onset myopathy, myoclonus, leukoencephalopathy, neurosensory hypoacusis, hypertrophic cardiomyopathy and insulin resistance. No other family member was affected, suggesting that our patient was a sporadic case. The T8306C mutation was heteroplasmic in several tissues of the proband, while it was...
