Mitochondrial TRNN gene
The mitochondrial gene MT-TN encodes a transport RNA (tRNA) for asparagine (N). The gene is encoded by nucleotides 5657-5729. Diseases caused by mutations include ophthalmoplegia and mitochondrial complex I deficiency. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
