RCV001354498 | SCV001549131 | likely pathogenic | Malignant tumor of breast | no assertion criteria provided | clinical testing | The BRCA2 p.Gly2274TrpfsX19 variant was not identified in the literature nor was it identified in the dbSNP, ClinVar, GeneInsight-COGR, Cosmic, MutDB, LOVD 3.0, UMD-LSDB, BIC, ARUP Laboratories, and Zhejiang Colon Cancer databases. The variant was not identified in the following control databases: the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, and the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The c.6819delinsGT variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 2274 and leads to a premature stop codon at position 2292. This alteration is then predicted to result in a truncated or absent protein and loss of function. Loss of function variants of the BRCA2 gene are an established mechanism of disease in hereditary breast and ovarian cancer and is the type of variant expected to cause the disorder. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more pathogenic role for this variant. This variant is classified as likely pathogenic. |
