Invitae RCV000530330 SCV000635263 uncertain significance Hereditary breast and ovarian cancer syndrome 2018-07-05 criteria provided, single submitter clinical testing This sequence change deletes 3 nucleotides from exon 11 of the BRCA2 mRNA (c.3071_3073delTTA). This leads to the deletion of 1 amino acid residue in the BRCA2 protein (p.Ile1024del) but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs754836679, ExAC 0.002%). This variant has not been reported in the literature in individuals with a BRCA2-related disease. ClinVar contains an entry for this variant (Variation ID: 187582). Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acid is currently unknown. In summary, this variant is a rare in-frame deletion with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
