T15465G MUTATION, ALTERED METHIONINE TO TERMINATION CODON OF THE MTDNA CYT B GENE, WAS FOUND IN A MAN WITH MYOPATHY
The mitochondrial myopathies are neuromuscular diseases that can be associated with mitochondrial DNA mutations. A 27-year-old man of four members in the family has been demonstrated positively detected to myopathy, whereas the molecular studies underlying this disorder are still unknown. Mitochondr...

The mitochondrial myopathies are neuromuscular diseases that can be associated with mitochondrial DNA mutations.
