Mitochondrial TRNS2 gene

The mitochondrial gene MT-TS2 encodes a transport RNA (tRNA) for serine (S), triplet AGY (Y for C or U). Diseases caused by mutations include MELAS and MERF syndroms, ataxia, and cataract. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
