Genes affected

GATB (HGNC:8849): (glutamyl-tRNA amidotransferase subunit B) Enables glutaminyl-tRNA synthase (glutamine-hydrolyzing) activity. Involved in glutaminyl-tRNAGln biosynthesis via transamidation and mitochondrial translation. Located in mitochondrion. Part of glutamyl-tRNA(Gln) amidotransferase complex. Implicated in combined oxidative phosphorylation deficiency 41. [provided by Alliance of Genome Resources, Apr 2022]
