Integrated Genetics/Laboratory Corporation of America RCV000429461 SCV000918953 uncertain significance not specified 2018-08-31 criteria provided, single submitter clinical testing Variant summary: BRCA2 c.7307A>T (p.Asn2436Ile) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 246016 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. The variant, c.7307A>T, has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer and fallopian tube carcinoma (Choi_2018, Kim_2017, Ikeda_2001, and Park_2017). These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. IARC class based on posterior probability from multifactorial likelihood analysis suggests the variant to be benign (Lindor_2012, Easton_2007). Additionally, odds ratios from a case control study also support the benign role of the variant (Park_2017). Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as VUS-possibly benign variant.
