Ambry Genetics RCV000562211 SCV000668873 uncertain significance Hereditary cancer-predisposing syndrome 2023-09-01 criteria provided, single submitter clinical testing The p.I504T variant (also known as c.1511T>C), located in coding exon 10 of the BRIP1 gene, results from a T to C substitution at nucleotide position 1511. The isoleucine at codon 504 is replaced by threonine, an amino acid with similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Color Diagnostics, LLC DBA Color Health RCV000562211 SCV000912106 uncertain significance Hereditary cancer-predisposing syndrome 2023-03-15 criteria provided, single submitter clinical testing This missense variant replaces isoleucine with threonine at codon 504 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD), but has been identified in a woman older than age 70 years with no personal history of cancer (FLOSSIES; https://whi.color.com/). 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV001071902 SCV001237234 uncertain significance Familial cancer of breast; Fanconi anemia complementation group J 2022-07-05 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 504 of the BRIP1 protein (p.Ile504Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 483143). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
