Ambry Genetics RCV000564033 SCV000663652 uncertain significance Hereditary cancer-predisposing syndrome 2016-02-23 criteria provided, single submitter clinical testing The p.S557A variant (also known as c.1669T>G), located in coding exon 11 of the RAD50 gene, results from a T to G substitution at nucleotide position 1669. The serine at codon 557 is replaced by alanine, an amino acid with similar 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 6501 samples (13002 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 120000 alleles tested) in our clinical cohort. This amino acid position is 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.
