RCV001862483 | SCV002131093 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2021-07-06 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change falls in intron 5 of the BRCA1 gene. It does not directly change the encoded amino acid sequence of the BRCA1 protein. It affects a nucleotide within the consensus splice site of the intron. This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. Experimental studies have shown that this variant affects BRCA1 protein function (PMID: 30209399). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. ClinVar contains an entry for this variant (Variation ID: 865383). 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. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. |
