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.

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 461061). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change falls in intron 8 of the BRIP1 gene. It does not directly change the encoded amino acid sequence of the BRIP1 protein. -
