Variant summary: The PALB2 c.1696C>T (p.Arg566Cys) variant involves the alteration of a non-conserved nucleotide and 2/4 in silico tools (SNPsandGO not captured due to low reliability index) predict a benign outcome, although these predictions have yet to be functionally assessed. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 1/95648, which does not exceed the estimated maximal expected allele frequency of a pathogenic PALB2 variant (0.0001563). A publication cites the variant in an affected individual, although with limited information (ie, lack of cosegregation data). A clinical diagnostic laboratory cites the variant with a classification of "uncertain significance." Therefore, until additional information becomes available (ie, clinical and functional data), the variant of interest has been classified as a "Variant of Uncertain Significance (VUS)." (less)

The p.R566C variant (also known as c.1696C>T), located in coding exon 5 of the PALB2 gene, results from a C to T substitution at nucleotide position 1696. The arginine at codon 566 is replaced by cysteine, an amino acid with highly dissimilar properties. This variant was reported in 0/60,466 breast cancer cases and in 1/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). 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. (less)

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 566 of the PALB2 protein (p.Arg566Cys). 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 missense change has been observed in individual(s) with breast and/or ovarian cancer and/or suspected Lynch syndrome (PMID: 25980754, 34326862, 35610400). ClinVar contains an entry for this variant (Variation ID: 410109). 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 with a negative predictive value of 80%. 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. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
