| Ambry Genetics | RCV000215083 | SCV000277368 | likely benign | Hereditary cancer-predisposing syndrome | 2015-07-16 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |

RCV000483990 | SCV000571680 | uncertain significance | not provided | 2016-09-14 | criteria provided, single submitter | clinical testing | This variant is denoted BRCA1 c.4343G>A at the cDNA level, p.Ser1448Asn (S1448N) at the protein level, and results in the change of a Serine to an Asparagine (AGC>AAC). Using alternate nomenclature, this variant would be defined as BRCA1 4462G>A. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRCA1 Ser1448Asn was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Serine and Asparagine share similar properties, this is considered a conservative amino acid substitution. BRCA1 Ser1448Asn occurs at a position that is not conserved and is located in the SCD domain and the regions of interaction with ATM, CHEK2, CDK2 and BRCA2 (Chen 1998, Narod 2004, Clark 2012). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether BRCA1 Ser1448Asn is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. |
