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.

The BRIP1 p.Lys234Lys variant was not identified in the literature nor was it identified in the Cosmic, MutDB, and Zhejiang Colon Cancer databases. The variant was identified in dbSNP (ID: rs45512798) as â€šÃ„ÃºWith Likely benign alleleâ€šÃ„Ã¹, in ClinVar and Clinvitae databases as benign by GeneDx and as likely benign by Ambry Genetics, Invitae, Counsyl and Colon Genomics Inc. The variant was identified in the NHLBI GO Exome Sequencing Project in 1 of 8600 European American and 1 of 4406 African American alleles. The variant was identified in control databases in 12 of 245898 chromosomes at a frequency of 0.00005 (Genome Aggregation Database Feb 27, 2017). Observations by population include African in 1 of 15302 chromosomes (freq: 0.00006), European Non-Finnish in 11 of 111400 chromosomes (freq: 0.0001); the variant was not observed in the â€šÃ„ÃºOtherâ€šÃ„Ã¹, Latino, Ashkenazi Jewish, East Asian, European Finnish, and South Asian populations. The variant was identified in 1 individual with breast cancer in our laboratory, co-occurring with a pathogenic ATM variant (c.2284_2285del, p.Leu762ValfsX2), increasing the likelihood the variant has little clinical significance. The p.Lys234= 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. -
