Mitochondrial TRNG gene

The mitochondrial gene MT-TG encodes a transport RNA (tRNA) for glycine (G). The gene is encoded by nucleotides 9991-10058. Diseases caused by mutations include cardiomyopathy, exercise intolerance, and sudden infant death syndrome. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
