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.

The PALB2 p.Leu604= variant was identified in 1 of 558 proband chromosomes (frequency: 0.002) from individuals or families with breast cancer and was not identified in 520 control chromosomes from healthy individuals (Zheng 2012). The variant was also identified in the following databases: dbSNP (ID: rs144015319) as "With other allele", ClinVar (classified as benign by Invitae, GeneDx, Color Genomics; as likely benign by Ambry Genetics and Quest Diagnostics Nichols Institute San Juan Capistrano), Clinvitae, and in LOVD 3.0 (1x probably does not affect function). The variant was not identified in Cosmic, or Zhejiang University databases. The variant was identified in control databases in 151 of 277136 chromosomes at a frequency of 0.001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: African in 145 of 24032 chromosomes (freq: 0.01), Latino in 5 of 34418 chromosomes (freq: 0.0002), European in 1 of 126630 chromosomes (freq: 0.00001); it was not observed in the â€šÃ„ÃºOtherâ€šÃ„Ã¹, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The p.Leu604= 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 the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
