Genes affected
BRIP1 (HGNC:20473): (BRCA1 interacting helicase 1) The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations.

Uncertain significance, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The BRIP1 p.Lys308Lys variant was not identified in the literature nor was it identified in Cosmic, MutDB and Zhejiang Colon Cancer Database. The variant was identified in dbSNP (ID: rs374974885) “With Likely benign” allele, ClinVar (classified as likely benign by Invitae and GeneDx) and Clinvitae database (2X as likely benign). The variant was identified in control databases in 12 of 276616 chromosomes at a frequency of 0.00004 increasing the likelihood that this may be a low frequency benign variant in certain populations of origin (Genome Aggregation Consortium Feb 27, 2017). The p.Lys308Lys 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; however, the c.924A>G occurs 6 nucleotides into exon 08, and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of 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. -
