Description

The stop gained c.947C>G (p.Ser316Ter) variant in COQ2 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Ser316Ter variant is novel (not in any individuals) in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes.The nucleotide change in COQ2 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. However, since this variant is present in the penultimate exon functional studies will be required to prove protein truncation. For these reasons, this variant has been classified as Uncertain Significance. In the absence of another reportable variant the molecular diagnosis is not confirmed.
