Rare variants of mitochondrial DNA in a child with encephalomyopathy

Abstract

The paper considers a clinical case of a child with suspected mitochondrial encephalomyopathy: cyclic vomiting, evident fatigue, muscle weakness, headache, and difficulties in learning school material. The similar symptoms are noted in an older sibling; the mother suffers from type 1 diabetes mellitus. The entire mitochondrial genome was sequenced in the proband. Despite the fact that significantly pathogenetic variants have not been identified, there are a number of individual mitochondrial DNA characteristics that may be of clinical significance. Of particular interest are two variants: m.T8477C and C12562G, which have a sufficiently high pathogenic potential. To establish their role requires further investigations of mitochondrial DNA in the mother and sibling.
