Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Likely benign, criteria provided, single submitter | curation | University of Washington Department of Laboratory Medicine, University of Washington | Mar 23, 2023 | Missense variant in a coldspot region where missense variants are very unlikely to be pathogenic (PMID:31911673). - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 08, 2024 | The p.E1482G variant (also known as c.4445A>G), located in coding exon 10 of the BRCA2 gene, results from an A to G substitution at nucleotide position 4445. The glutamic acid at codon 1482 is replaced by glycine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
