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 submitter | clinical testing | GeneDx | May 02, 2017 | This variant is denoted BRIP1 c.537A>G at the DNA level. Although this variant is silent at the coding level, preserving a Glutamic Acid at codon 179, it is predicted to cause abnormal splicing. However, in the absence of RNA or functional studies, the actual effect of this variant is unknown. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRIP1 c.537A>G was not observed in large population cohorts (NHLBI Exome Sequencing Project, The 1000 Genomes Consortium 2015, Lek 2016). The nucleotide which is altered, an adenine (A) at base 537, is not conserved. Based on currently available information, it is unclear whether BRIP1 c.537A>G is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. - |

Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 23, 2014 | This alteration is classified as likely 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. - |
