Ambry Genetics | RCV000217028 | SCV000273404 | uncertain significance | Hereditary cancer-predisposing syndrome | 2015-01-13 | criteria provided, single submitter | clinical testing | The p.Q215H variant (also known as c.645A>T), located in coding exon 5 of the RAD50 gene, results from an A to T substitution at nucleotide position 645. The glutamine at codon 215 is replaced by histidine, 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 0.003% (greater than 40000 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 p.Q215H remains unclear. |
