Ambry Genetics | RCV000215943 | SCV000273029 | uncertain significance | Hereditary cancer-predisposing syndrome | 2014-11-17 | criteria provided, single submitter | clinical testing | The p.W156S variant (also known as c.467G>C), located in coding exon 4 of the ATM gene, results from a G to C substitution at nucleotide position 467. The tryptophan at codon 156 is replaced by serine, 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 6499 samples (12998 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.004% (greater than 22000 alleles tested) in our clinical cohort. This amino acid position is highly 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.W156S remains unclear. |
