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 was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 8: BayesDel_noAF, Cadd, Eigen, MutationAssessor, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when max_spliceai, M_CAP, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.01327613).

BP6

Variant 16-57452920-T-C is Benign according to our data. Variant chr16-57452920-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 214245.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000282 (43/152270) while in subpopulation SAS AF = 0.0085 (41/4822). AF 95% confidence interval is 0.00644. There are 0 homozygotes in GnomAd4. There are 33 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 7 AR gene
