Mitochondrial TRNE gene

The mitochondrial gene MT-TE encodes a transport RNA (tRNA) for glutamic acid (E). The gene is encoded by nucleotides 14674-14742. Diseases caused by mutations include myopathy, diabetes, and sensorineural deafness. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
