Ambry Genetics RCV000563644 SCV000661349 uncertain significance Hereditary cancer-predisposing syndrome 2016-08-23 criteria provided, single submitter clinical testing The p.C2549S variant (also known as c.7646G>C), located in coding exon 15 of the BRCA2 gene, results from a G to C substitution at nucleotide position 7646. The cysteine at codon 2549 is replaced by serine, 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 0.0003% (greater than 300000 alleles tested) in our clinical cohort. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
