Genes affected

ENTPD7 (HGNC:19745): (ectonucleoside triphosphate diphosphohydrolase 7) This gene encodes a purine-converting ectoenzyme which belongs to the ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase) family. The encoded protein hydrolyzes extracellular nucleoside triphosphates (UTP, GTP, and CTP) to nucleoside monophosphates as part of a purinergic signaling pathway. It contains two transmembrane domains at the N- and C-termini and a large, hydrophobic catalytic domain located in between. This gene affects oxidative stress as well as DNA damage and is a mediator of senescence. [provided by RefSeq, Mar 2017]

COX15 (HGNC:2263): (cytochrome c oxidase assembly homolog COX15) Cytochrome c oxidase (COX), the terminal component of the mitochondrial respiratory chain, catalyzes the electron transfer from reduced cytochrome c to oxygen. This component is a heteromeric complex consisting of 3 catalytic subunits encoded by mitochondrial genes and multiple structural subunits encoded by nuclear genes. The mitochondrially-encoded subunits function in electron transfer, and the nuclear-encoded subunits may function in the regulation and assembly of the complex. This nuclear gene encodes a protein which is not a structural subunit, but may be essential for the biogenesis of COX formation and may function in the hydroxylation of heme O, according to the yeast mutant studies. This protein is predicted to contain 5 transmembrane domains localized in the mitochondrial inner membrane. Alternative splicing of this gene generates two transcript variants diverging in the 3' region. [provided by RefSeq, Jul 2008]

CUTC (HGNC:24271): (cutC copper transporter) Members of the CUT family of copper transporters are associated with copper homeostasis and are involved in the uptake, storage, delivery, and efflux of copper (Gupta et al., 1995 [PubMed 7635807]; Li et al., 2005 [PubMed 16182249]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP6: Variant 10-99711101-C-CAA is Benign according to our data. Variant chr10-99711101-C-CAA is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 298386.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0156 (12802/822960) while in subpopulation NFE AF= 0.0161 (12135/752604). AF 95% confidence interval is 0.0159. There are 91 homozygotes in gnomad4_exome. There are 5957 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 7 AR gene
