RCV001227125 | SCV001399466 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2019-09-09 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with BRCA2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces phenylalanine with leucine at codon 1142 of the BRCA2 protein (p.Phe1142Leu). The phenylalanine residue is weakly conserved and there is a small physicochemical difference between phenylalanine and leucine. |

Ambry Genetics | RCV003158558 | SCV004915394 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-09-28 | criteria provided, single submitter | clinical testing | The c.3424T>C (p.F1142L) alteration is located in exon 11 (coding exon 10) of the BRCA2 gene. This alteration results from a T to C substitution at nucleotide position 3424, causing the phenylalanine (F) at amino acid position 1142 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
