Ambry Genetics | RCV001009902 | SCV001170029 | uncertain significance | Hereditary cancer-predisposing syndrome | 2018-07-24 | criteria provided, single submitter | clinical testing | The p.N368K variant (also known as c.1104T>A), located in coding exon 4 of the PALB2 gene, results from a T to A substitution at nucleotide position 1104. The asparagine at codon 368 is replaced by lysine, an amino acid with similar properties. This amino acid position is poorly 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. |

RCV001221199 | SCV001393225 | uncertain significance | Familial cancer of breast | 2023-02-06 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 368 of the PALB2 protein (p.Asn368Lys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with PALB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 818370). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PALB2 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. |
