Ambry Genetics RCV000570507 SCV000675343 pathogenic Hereditary cancer-predisposing syndrome 2020-09-18 criteria provided, single submitter clinical testing The p.Y220N pathogenic mutation (also known as c.658T>A), located in coding exon 5 of the TP53 gene, results from a T to A substitution at nucleotide position 658. The tyrosine at codon 220 is replaced by asparagine, an amino acid with dissimilar properties. This variant is in the DNA binding domain of the TP53 protein and is reported to have loss of transactivation in yeast based assays (IARC TP53 database: 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 (Kotler E et al. Mol. Cell 2018 Jul;71:178-190.e8; Giacomelli AO et al. Nat. Genet. 2018 Oct;50:1381-1387). Although this specific alteration has not been reported in the literature, another alteration at the same amino acid position (p.Y220C) has been reported in multiple individuals and families with classic Li-Fraumeni syndrome (Birch et al. Cancer Res. 1994 Mar 1;54(5):1298-304; Monti et al. Clin Cancer Res. 2007 Jul 1;13(13):3789-95; Melham-Bertrand et al. Cancer. 2012 Feb 15;118(4):908-13). Based on internal structural analysis, p.Y220N destabilizes a residue in an indicated functional domain to a greater degree than multiple pathogenic variants in the region (Cho Y et al. Science 1994 Jul;265:346-55). 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.
