| Ambry Genetics | RCV000166026 | SCV000216786 | uncertain significance | Hereditary cancer-predisposing syndrome | 2014-10-17 | criteria provided, single submitter | clinical testing | The p.D361Y variant (also known as c.1081G>T), located in coding exon 9 of the CHEK2 gene, results from a G to T substitution at nucleotide position 1081. The aspartic acid at codon 361 is replaced by tyrosine, an amino acid with highly 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 0.004% (greater than 26,000 alleles tested) in our clinical cohort. This amino acid position is well conserved through mammals, but not in lower 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.D361Y remains unclear. |
