Ambry Genetics RCV000219831 SCV000276671 uncertain significance Hereditary cancer-predisposing syndrome 2015-06-29 criteria provided, single submitter clinical testing The p.E49V variant (also known as c.146A>T and 374A>T), located in coding exon 2 of the BRCA2 gene, results from an A to T substitution at nucleotide position 146. The glutamic acid at codon 49 is replaced by valine, an amino acid with 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 0.001% (greater than 15000 alleles tested) in our clinical cohort. 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 p.E49V remains unclear.
