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 absent from his asymptomatic siblings. Single fibre analysis confirmed the segregation of higher mutational load in cytochrome c oxidase-deficient fibres. The mutation T8306C is predicted to disrupt a highly conserved base pair and was not found in more than 120 controls. This finding broadens the phenotypic and molecular spectrum of mitochondrial tRNA(Lys) associated disorders.
