GeneDx RCV000120300 SCV000108670 likely benign not specified 2018-02-20 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

The composite observed allele frequency in controls, including the large and diverse ExAC cohort, is 29/121594 (1/4193); and the observed allele frequency in the Latino sub-population from ExAC population is 11/11570 (1/1052). These frequencies are not significantly different than the maximal expected allele frequency for a pathogenic BRCA1 variant (1/1000). However, the low frequency in control populations should still suggest that this variant is a rare polymorphism unless proven other. The variant has been cited to co-occur with various pathogenic BRCA1 and BRCA2 variants, including BRCA1 c.6944_6947delTAAA (p.Ile2315_Lys2316?fs), BRCA1 c.2722G>T (p.Glu908Ter), and BRCA2 c.8537_8538delAG (p.Glu2846Glyfs) from BIC and BRCA2 c.1310_1313delAAGA (p.Lys437IlefsX22) from UMD. These co-occurrence findings are a clear evidence that this variant is benign. Although the variant has been reported in multiple patients in the literature, the publications did not comprehensively rule out the presence of large rearrangements. LOH studies demonstrated the retention of wild type allele and the loss of the allele harboring this variant in tumors from 2 patients, further supporting a benign outcome (Osorio et al, 2002). In addition, a cell growth assay to measure this variant's ability to functionally complement BRCA1-deficient mouse embryonic stem cells showed the variant behaves like wildtype (Bouwman et al, 2013). Although clinical laboratories and databases are mixed in their classifications, the majority classify the variant as benign/likely benign/neutral. Taken together, this variant has been classified as benign.
