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.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

In the published literature, the variant has been reported in affected individuals with breast cancer (PMID: 21932393), as well as unspecified cancers (PMIDs:26689913 (2015) and 28873162 (2017)). Additionally, a functional study suggests that the variant is not damaging to PALB2 protein function (PMIDs: 26689913 (2015) and 31636395 (2020)). The frequency of this variant in the general population, 0.00024 (6/24966 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -

In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Published functional studies demonstrate homology-directed repair activity comparable to wildtype (PMID: 31636395); Observed in individuals with breast or ovarian cancer (PMID: 21932393, 26689913, 35264596); This variant is associated with the following publications: (PMID: 21285249, 21932393, 19609323, 26689913, 28873162, 20871615, 24485656, 35264596, 31636395) -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: PALB2 c.3056T>C (p.Val1019Ala) results in a non-conservative amino acid change located in the WD40 domain that binds to the N-terminus of BRCA2 (IPR031920) of the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change. The variant allele was found at a frequency of 1.3e-05 in 1614032 control chromosomes, predominantly at a frequency of 0.00024 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 1.54 fold of the estimated maximal expected allele frequency for a pathogenic variant in PALB2 causing Breast Cancer phenotype (0.00016). c.3056T>C has been observed in individual(s) affected with Breast Cancer (Zheng_2012, Lu_2015, Mandelker_2017), but without strong evidence for causality. These report(s) do not provide unequivocal conclusions about association of the variant with Breast Cancer. Co-occurrences with other pathogenic variant(s) have been reported (PALB2 c.1479delC, p.Thr494LeufsX67), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 21932393, 26689913, 28873162). ClinVar contains an entry for this variant (Variation ID: 126709). Based on the evidence outlined above, the variant was classified as likely benign. -
