Ambry Genetics RCV000214465 SCV000276833 uncertain significance Hereditary cancer-predisposing syndrome 2015-06-28 criteria provided, single submitter clinical testing The p.G2140V variant (also known as c.6419G>T and 6647G>T), located in coding exon 10 of the BRCA2 gene, results from a G to T substitution at nucleotide position 6419. The glycine at codon 2140 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 6494 samples (12988 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 150000 alleles tested) in our clinical cohort. This amino acid position is poorly 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.G2140V remains unclear.
