Hereditary cancer-predisposing syndrome Uncertain:2
This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 72 of the RAD50 protein (p.Val72Ile). This variant is present in population databases (rs118029772, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. ClinVar contains an entry for this variant (Variation ID: 141106). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The isoleucine 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. -
The p.V72I variant (also known as c.214G>A) is located in coding exon 3 of the RAD50 gene. The valine at codon 72 is replaced by isoleucine, an amino acid with highly similar properties. This change occurs in the first base pair of coding exon 3. This alteration was identified in a cohort of 481 Chinese breast cancer patients with family history of breast/ovarian cancer (Wang J et al. Cancer Med, 2019 05;8:2074-2084). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
