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, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthDec 11, 2023This variant causes an A>G nucleotide substitution at the +6 position of intron 10 of the BRIP1 gene. Splice site prediction tools predict that this variant may not have a significant impact on RNA splicing. To our knowledge, RNA studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 7/235660 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Uncertain significance, criteria provided, single submitterclinical testingGenetic Services Laboratory, University of ChicagoNov 19, 2021DNA sequence analysis of the BRIP1 gene demonstrated a sequence change in intron 10, c.1473+6A>G. This sequence change has been described in the gnomAD database with a frequency of 0.06% in the Ashkenazi Jewish subpopulation (dbSNP rs587780827). Based on in-silico splice prediction programs, this sequence change may affect normal splicing of the BRIP1 gene, which would result in an abnormal protein, however functional studies have not been performed to prove this conclusively. This change does not appear to have been previously described in individuals with BRIP1-related disorders. It is possible that this sequence change represents a benign sequence change in the BRIP1 gene that has not been identified to date. The functional significance of this sequence change is not known at present and its contribution to this individual's disease phenotype cannot definitively be determined. -
