Illumina Laboratory Services, Illumina	RCV000327932	SCV000396117	likely benign	Fanconi anemia complementation group N	2017-04-27	criteria provided, single submitter	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 allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

The variant is present in the control population dataset of ExAC at an overall allele frequency of 0.073% (88/121172 chrs tested), mainly in individuals of European descent (0.1154%; 77/66698 chrs tested). The observed frequency exceeds the maximum expected allele frequency for a pathogenic PALB2 variant (0.015%), suggesting that it is a common polymorphism. Based on the published reports, the variant of interest was found in affected individuals as well as in unaffected controls without personal or family history of cancer. Lastly, the variant has been reported as Benign by multiple reputable database/clinical laboratories. Taken together, the variant was classified as Benign.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV001357080	SCV001552421	benign	Malignant tumor of breast		no assertion criteria provided	clinical testing	The PALB2 p.Val398= variant was identified in 10 of 7040 proband chromosomes (frequency: 0.001) from individuals or families with breast and ovarian cancers of Spanish, Italian, German, and Australian nationalities and was present in 9 of 6464 control chromosomes (frequency: 0.001) from healthy individuals (Blanco 2012, Catucci 2014, Hellebrand 2011, Thompson 2015). The variant was also identified in dbSNP (ID: rs61755173) as “with Likely benign, other allele”, in ClinVar and Clinvitae databases as benign by Invitae, GeneDx, PALB2 database and likely benign by Ambry Genetics, Cancer Genetics Laboratory, Peter MacCallum Cancer Centre, and Illumina Clinical Services; and identified 2X in the LOVD 3.0 database. The variant was not identified in Cosmic, MutDB, Zhejiang Colon Cancer databases. The variant was identified in the 1000 Genomes Project in 4 of 5000 chromosomes (frequency: 0.0008) and in the NHLBI GO Exome Sequencing Project in 20 of 8600 European American African alleles. In addition, the variant was identified in control databases in 212 of 276616 chromosomes at a frequency of 0.0008 in the following populations: African in 9 of 24030 chromosomes (freq. 0.0004), Latino in 19 of 34416 chromosomes (freq. 0.0006), European Non-Finnish in 170 of 126264 chromosomes (freq. 0.001), Ashkenazi Jewish in 9 of 10148 chromosomes (freq. 0.0009), European Finnish in 1 of 25660 chromosomes (freq. 0.00004), and Other in 4 of 6454 chromosomes (freq. 0.0006) but was not seen in East Asian and South Asian POP populations increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The p.Val398= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, 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.
