Variant summary
Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM1PM2PP3_Moderate
The NM_007194.4(CHEK2):c.344T>C(p.Phe115Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,798 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. F115C) has been classified as Uncertain significance.

Familial cancer of breast Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 24, 2023 | This variant is not present in population databases (gnomAD no frequency). This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 115 of the CHEK2 protein (p.Phe115Ser). This variant has not been reported in the literature in individuals affected with CHEK2-related conditions. 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 410040). - |
