Ambry Genetics RCV000217767 SCV000276095 uncertain significance Hereditary cancer-predisposing syndrome 2015-05-21 criteria provided, single submitter clinical testing The p.L189V variant (also known as c.565T>G), located in coding exon 5 of the RAD50 gene, results from a T to G substitution at nucleotide position 565. The leucine at codon 189 is replaced by valine, an amino acid with highly 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 6503 samples (13006 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.002% (greater than 65000 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 probably damaging and deleterious by PolyPhen and SIFT in silico analyses, respectively. Since supporting evidence is limited at this time, the clinical significance of p.L189V remains unclear.
