The p.G279E variant (also known as c.836G>A), located in coding exon 7 of the TP53 gene, results from a G to A substitution at nucleotide position 836. The glycine at codon 279 is replaced by glutamic acid, an amino acid with a few similar properties. <span style="background-color:initial">Per the IARC TP53 Database, this alteration has been reported as a somatic alteration 53 times, however this has not been reported as a germline alteration in any Li-Fraumeni syndrome families (Petitjean A et al. IARC TP53 database [version R16, November 2012]. Hum Mutat. 2007 Jun;28(6):622-9). <span style="background-color:initial">This alteration is located in the functionally critical DNA-binding domain. A number of functional assays in both yeast and mammalian cells have shown this alteration to be devoid of transactivation activity, deficient in the induction of apoptosis, and unable to suppress cell growth after UV irradiation (Kato S et al.Proc Natl Acad Sci USA<span style="background-color:initial">. 2003 Jul 8;100(14):8424-9; Menendez D, Mol. Cell. Biol.<span style="background-color:initial"> 2006 Mar; 26(6):2297-308; <span style="background-color:initial">Inga A, Oncogene 2001 Jan; 20(4):501-13; <span style="background-color:initial">Rokudai Set al. J Biol Chem. 2009 Jan 2;284(1):237-44). <span style="background-color:initial">Additionally, this variant has been shown to exhibit strong dominant negative characteristics (<span style="background-color:initial">Dearth LR, Carcinogenesis 2007 Feb; 28(2):289-98; <span style="background-color:initial">Brachmann RK, Proc. Natl. Acad. Sci. U.S.A. 1996 Apr; 93(9):4091-5<span style="background-color:initial">). Structural analysis indicates that G279 is adjacent to several DNA binding residues, and the p.G279E change creates severe structural perturbations (>15 kcal/mol) resulting in a destabilization of the proper folding of the adjacent loop (internal analysis). 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). <span style="background-color:initial">This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico <span style="background-color:initial">analysis. <span style="background-color:initial">Based on the majority of available evidence to date, this variant is likely to be pathogenic.
