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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000329 (48/1460786) while in subpopulation MID AF= 0.00052 (3/5768). AF 95% confidence interval is 0.000141. There are 0 homozygotes in gnomad4_exome. There are 24 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.46G>A (p.G16S) alteration is located in exon 2 (coding exon 2) of the QRSL1 gene. This alteration results from a G to A substitution at nucleotide position 46, causing the glycine (G) at amino acid position 16 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
