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.

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

The BRIP1 p.Ile746Val variant was identified in 3 of 7992 proband chromosomes (frequency: 0.0004) from individuals or families with Lynch or ovarian cancer and was present in 4 of 8224 control chromosomes (frequency: 0.0005) from healthy individuals (Ramus 2015, Yurgelun 2015). The variant was also identified in dbSNP (ID: rs111536363) as "With other allele", ClinVar (classified as benign by Invitae, GeneDx, Ambry Genetics, Counsyl and two clinical laboratories; as likely benign by tree clincal laboratories), MutDB, and in Zhejiang University, databases. The variant was not identified in Cosmic, database. The variant was identified in control databases in 387 of 276970 chromosomes (6 homozygous) at a frequency of 0.001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 361 of 24026 chromosomes (freq: 0.01), Other in 2 of 6462 chromosomes (freq: 0.0003), Latino in 18 of 34408 chromosomes (freq: 0.0005), European in 3 of 126534 chromosomes (freq: 0.00002), East Asian in 1 of 18864 chromosomes (freq: 0.00005), and South Asian in 2 of 30744 chromosomes (freq: 0.00007), while the variant was not observed in the Ashkenazi Jewish, and Finnish, populations. The p.Ile746 residue is conserved in mammals but not in more distantly related organisms however four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) 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. -
