Genes affected
COQ9 (HGNC:25302): (coenzyme Q9) This locus represents a mitochondrial ubiquinone biosynthesis gene. The encoded protein is likely necessary for biosynthesis of coenzyme Q10, as mutations at this locus have been associated with autosomal-recessive neonatal-onset primary coenzyme Q10 deficiency.[provided by RefSeq, Sep 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.41).
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000217 (33/152314) while in subpopulation SAS AF= 0.00683 (33/4832). AF 95% confidence interval is 0.005. There are 1 homozygotes in gnomad4. There are 23 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Submissions by phenotype

Encephalopathy-hypertrophic cardiomyopathy-renal tubular disease syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
