| Ambry Genetics | RCV000567139 | SCV000668665 | uncertain significance | Hereditary cancer-predisposing syndrome | 2016-06-10 | criteria provided, single submitter | clinical testing | The p.Y2826C variant (also known as c.8477A>G), located in coding exon 18 of the BRCA2 gene, results from an A to G substitution at nucleotide position 8477. The tyrosine at codon 2826 is replaced by cysteine, an amino acid with highly dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6503 samples (13006 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.0003% (greater than 300000 alleles tested) in our clinical cohort. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
