Ambry Genetics | RCV001026817 | SCV001189273 | uncertain significance | Hereditary cancer-predisposing syndrome | 2018-03-26 | criteria provided, single submitter | clinical testing | The p.Q260R variant (also known as c.779A>G), located in coding exon 4 of the PALB2 gene, results from an A to G substitution at nucleotide position 779. The glutamine at codon 260 is replaced by arginine, an amino acid with highly similar properties. 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. |

RCV001873420 | SCV002109868 | uncertain significance | Familial cancer of breast | 2023-05-15 | criteria provided, single submitter | clinical testing | 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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 827257). This variant has not been reported in the literature in individuals affected with PALB2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 260 of the PALB2 protein (p.Gln260Arg). |
