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.

Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The BRIP1 p.Leu195Pro variant was identified in 21 of 13772 proband chromosomes (frequency: 0.002) from individuals or families with prostate cancer, breast cancer, ovarian cancer, and Lynch syndrome and was present in 19 of 21561 control chromosomes (frequency: 0.0009) from healthy individuals (Bodian 2014, Kote-Jarai 2009, Kuusisto 2011, Lewis 2005, Rafnar 2011, Ramus 2015, Ray 2009, Rutter 2003, Seal 2006, Yurgelun 2015). The variant was also identified in the following databases: dbSNP (ID: rs4988347) as "With Likely benign allele", ClinVar (4x benign, 3x likely benign), Clinvitae, and the Zhejiang Colon Cancer Database (6x, likely neutral). The variant was not identified in Cosmic or the MutDB database. The variant was identified in control databases in 537 of 277082 chromosomes (2 homozygous) at a frequency of 0.002 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 8 of 24028 chromosomes (freq: 0.0003), Other in 10 of 6464 chromosomes (freq: 0.002), Latino in 24 of 34414 chromosomes (freq: 0.0007), European in 255 of 126622 chromosomes (freq: 0.002), Finnish in 226 of 25772 chromosomes (freq: 0.009), and South Asian in 14 of 30782 chromosomes (freq: 0.0005). The variant was not observed in the Ashkenazi Jewish or East Asian populations. A study by Lewis 2005 utilizing in silico bioinformatic tools predicted this variant may affect mRNA folding and exonic splicing enhancers. However, the same study showed that the variant did not segregate with disease in a family with breast cancer (Lewis 2005). The p.Leu195 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and 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. -

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
