Mitochondrial TRNS1 gene

The mitochondrial gene MT-TS1 encodes a transport RNA (tRNA) for serine (S), triplet UCN (N for C, U, G or A). The gene is encoded by nucleotides 7445-7516. Diseases caused by mutations include MELAS and MERFF syndromes, palmoplantar keratoderma, cytochrome c oxydase deficiency, sensorineural deafness, exercise intolerance, and lactic acidosis. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
