Variant chr5-132866991-A-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_014402.5(UQCRQ):c.110A>C(p.Asn37Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,613,920 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N37S) has been classified as Uncertain significance.

Genes affected

UQCRQ (HGNC:29594): (ubiquinol-cytochrome c reductase complex III subunit VII) This gene encodes a ubiquinone-binding protein of low molecular mass. This protein is a small core-associated protein and a subunit of ubiquinol-cytochrome c reductase complex III, which is part of the mitochondrial respiratory chain. [provided by RefSeq, Jul 2008]

This sequence change replaces asparagine, which is neutral and polar, with threonine, which is neutral and polar, at codon 37 of the UQCRQ protein (p.Asn37Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with UQCRQ-related conditions. ClinVar contains an entry for this variant (Variation ID: 1958085). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
