WARS2 encodes a tryptophanyl tRNA synthetase, which is involved in mitochondrial protein synthesis. Biallelic mutations in WARS2 are rare and have been associated with a spectrum of clinical presentations, including neurodevelopmental disorder with abnormal movements, lactic acidosis with or without seizures (NEMMLAS).
