Genes affected
AARS2 (HGNC:21022): (alanyl-tRNA synthetase 2, mitochondrial) The protein encoded by this gene belongs to the class-II aminoacyl-tRNA synthetase family. Aminoacyl-tRNA synthetases play critical roles in mRNA translation by charging tRNAs with their cognate amino acids. The encoded protein is a mitochondrial enzyme that specifically aminoacylates alanyl-tRNA. Mutations in this gene are a cause of combined oxidative phosphorylation deficiency 8.

TMEM151B (HGNC:21315): (transmembrane protein 151B) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
