Department of Pathology and Laboratory Medicine, Sinai Health System RCV000499699 SCV000592121 uncertain significance Malignant tumor of breast no assertion criteria provided clinical testing The BRCA2 p.Ser2509Asn variant was not identified in the literature nor was it identified in the dbSNP, Clinvitae database, Fanconi Anemia Mutation Database (LOVD), LOVD-IARC database, ARUP Laboratories BRCA Mutations Database, COSMIC, the ClinVar database, GeneInsight COGR database, the BIC database, UMD and Fanconi Anemia Mutation Database (LOVD) databases. The p.Ser2509 residue is conserved across mammals and other organisms, and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the p.Ser2509Asn variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and 2 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing. However, this information is not predictive enough to assume pathogenicity. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
