Ambry Genetics RCV002338161 SCV002644709 pathogenic Hereditary cancer-predisposing syndrome 2022-01-24 criteria provided, single submitter clinical testing The p.E171G pathogenic mutation (also known as c.512A>G), located in coding exon 4 of the TP53 gene, results from an A to G substitution at nucleotide position 512. The glutamic acid at codon 171 is replaced by glycine, an amino acid with similar properties. This variant is in the DNA binding domain of the TP53 protein and is reported to have non-functional transactivation in yeast based assays (Kato S et al. Proc. Natl. Acad. Sci. USA. 2003 Jul;100:8424-9). Studies conducted in human cell lines indicate this alteration is deficient at growth suppression and has a dominant negative effect (Kotler E et al. Mol.Cell. 2018 Jul;71:178-190.e8; Giacomelli AO et al. Nat. Genet. 2018 Oct;50:1381-1387). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.
