Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM1PM2PP3
The NM_007194.4(CHEK2):c.1114T>G(p.Ser372Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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. S372C) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 19, 2017 | The p.S372A variant (also known as c.1114T>G), located in coding exon 10 of the CHEK2 gene, results from a T to G substitution at nucleotide position 1114. The serine at codon 372 is replaced by alanine, an amino acid with similar properties. This serine is a target of phosphorylation, and a substitution with alanine has been shown in a cell system to be associated with a reduction of kinase response to radiation-induced DNA damage (Guo X et al, J. Biol. Chem. 2010 Oct;285(43):33348-57). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
Familial cancer of breast Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 21, 2021 | This sequence change replaces serine with alanine at codon 372 of the CHEK2 protein (p.Ser372Ala). The serine residue is highly conserved and there is a moderate physicochemical difference between serine and alanine. 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. Experimental studies have shown that this missense change affects CHEK2 function (PMID: 20713355). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 479570). This variant has not been reported in the literature in individuals affected with CHEK2-related conditions. This variant is not present in population databases (ExAC no frequency). - |
