Genes affected

PALB2 (HGNC:26144): (partner and localizer of BRCA2) This gene encodes a protein that may function in tumor suppression. This protein binds to and colocalizes with the breast cancer 2 early onset protein (BRCA2) in nuclear foci and likely permits the stable intranuclear localization and accumulation of BRCA2.

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 tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with a PALB2-related disease. This variant is present in population databases (rs560839514, ExAC 0.01%). This sequence change replaces proline with serine at codon 529 of the PALB2 protein (p.Pro529Ser). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and serine. In summary, this variant has uncertain impact on PALB2 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
