Gene: [11q1/COX8] cytochrome c oxidase subunit VIII (cytochrome a3/aa3); mitochondrial myopathy? (MIM:220110);


FUN

The reaction catalyzed: 4 ferrocytochrome c + O(2) = 4 ferricytochrome c + 2 H(2)O."

HET

Several types of hereditary deficiency of the mitochondrial respiratory chain complex IV are known. Since total number of various peptides included in this complex approaches 20, one may expect a high degree of clinical genetic heterogeneity in the array of corresponding syndromes. A relationship with alterations of complex IV catalytic peptides encoded by three mitochondrial genes was demonstrated for some of them (those well-defined mitochondrial myopathy)."
