Description

This missense change has been observed in individual(s) with breast cancer (PMID: 25186627). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 549 of the PALB2 protein (p.His549Arg). ClinVar contains an entry for this variant (Variation ID: 654612). 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. 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.
