Genes affected

TARS2 (HGNC:30740): (threonyl-tRNA synthetase 2, mitochondrial) This gene encodes a member of the class-II aminoacyl-tRNA synthetase family. The encoded protein is a mitochondrial aminoacyl-tRNA synthetase. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 4.
