Invitae RCV000637814 SCV000759293 uncertain significance Hereditary breast and ovarian cancer syndrome 2018-10-24 criteria provided, single submitter clinical testing This sequence change replaces isoleucine with threonine at codon 729 of the BRCA2 protein (p.Ile729Thr). The isoleucine residue is moderately conserved and there is a moderate physicochemical difference between isoleucine and threonine. This variant is present in population databases (rs431825296, ExAC 0.01%). This variant has been reported in individuals affected with breast cancer (PMID: 28222693, 27257965). ClinVar contains an entry for this variant (Variation ID: 96780). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The threonine 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. 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.
