Mitochondrial TRNV gene

The mitochondrial gene MT-TV encodes a transport RNA (tRNA) for valine (V). The gene is encoded by nucleotides 1602-1670. Diseases caused by mutations include Leigh syndrome, ataxia, seizures, dementia, sensorineural deafness, and Charcot–Marie–Tooth disease. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
