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.

This alteration is classified as 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: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -

Significance: Benign

Review Status: no assertion criteria provided

Collection Method: clinical testing

The PALB2 p.Pro210Leu variant was identified in 65 of 10554 proband chromosomes (frequency: 0.006) from individuals or families with breast cancer and was present in 37 of 8955 control chromosomes (frequency: 0.0005) from healthy individuals (Rahman_2007_17200668, Garcia_2009_18302019, Ding_2011_21113654, Zheng_2012_21932393, Tischkowitz_2012_22241545, Thompson_2015_26283626). The variant was also identified in the following databases: dbSNP (ID: rs57605939) as â€šÃ„ÃºWith other alleleâ€šÃ„Ã¹, ClinVar (8x, as benign by Invitae, Ambry, EGL Genetic, Color Genomics, Illumina, Pathway Genomics, PALB2 database, 2x as likely benign, by Cancer Genetics, Institute for Biomarker, 1x as uncertain significant by ITMI), Clinvitae (3x as benign and 3x with conflicting interpretations of pathogenicity by ClinVar and EmvClass), LOVD 3.0 (5x). The variant was not identified in Cosmic, MutDB, and Zhejiang Colon Cancer Databases. The variant was identified in control databases in 1750 of 277182 chromosomes (51 homozygous) at a frequency of 0.006 increasing the likelihood this could be a low frequency variant (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include African in 1618 of 24022 chromosomes (freq: 0.07), other in 13 of 6468 chromosomes (freq: 0.002), Latino in 105 of 34420 chromosomes (freq: 0.003), European Non-Finnish in 10 of 126682 chromosomes (freq: 0.00008), Ashkenazi Jewish in 1 of 10152 chromosomes (freq: 0.0001), and South Asian in 3 of 30782 chromosomes (freq: 0.0001), while the variant was not observed in the East Asian, European Finnish, populations. The p.Pro210Leu residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
