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]

Uncertain significance, criteria provided, single submitter	clinical testing	CeGaT Center for Human Genetics Tuebingen	Oct 31, 2016	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Sep 06, 2022	This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1616 of the ATR protein (p.Ser1616Ala). This variant is present in population databases (rs201492267, gnomAD 0.05%). 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: 425314). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
