Genes affected

QRSL1 (HGNC:21020): (glutaminyl-tRNA amidotransferase subunit QRSL1) 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 40. [provided by Alliance of Genome Resources, Apr 2022]

QRSL1 Gene-Disease associations (from GenCC):

• combined oxidative phosphorylation deficiency 40
