Description

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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals with a PALB2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with leucine at codon 726 of the PALB2 protein (p.Pro726Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine.
