Genes affected

ATR (HGNC:882): (ATR serine/threonine kinase) The protein encoded by this gene is a serine/threonine kinase and DNA damage sensor, activating cell cycle checkpoint signaling upon DNA stress. The encoded protein can phosphorylate and activate several proteins involved in the inhibition of DNA replication and mitosis, and can promote DNA repair, recombination, and apoptosis. This protein is also important for fragile site stability and centrosome duplication. Defects in this gene are a cause of Seckel syndrome 1. [provided by RefSeq, Aug 2017]

The ATR c.2875G>C variant is predicted to result in the amino acid substitution p.Val959Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0044% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-142269075-C-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 959 of the ATR protein (p.Val959Leu). This variant is present in population databases (rs28910271, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with ATR-related conditions. ClinVar contains an entry for this variant (Variation ID: 1430379). 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 tolerated. 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. -
