Genes affected

TP53 (HGNC:11998): (tumor protein p53) This gene encodes a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. The encoded protein responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in this gene are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome. Alternative splicing of this gene and the use of alternate promoters result in multiple transcript variants and isoforms. Additional isoforms have also been shown to result from the use of alternate translation initiation codons from identical transcript variants (PMIDs: 12032546, 20937277).

For these reasons, this variant has been classified as Pathogenic. This variant disrupts the¬†p.Glu285¬†amino acid residue in TP53. Other variant(s) that disrupt this residue have been observed in individuals with TP53-related conditions (PMID:¬†11051239,¬†22507745, 23894400), suggesting that it is a clinically significant residue. As a result, variants that disrupt this residue are likely to be causative of disease. This variant has been reported to affect TP53 protein function (PMID: 12826609, 18762572, 25584008). This variant has been observed to be de novo in an individual affected with¬†pediatric adrenocortical carcinoma and choroid plexus carcinoma¬†(PMID: 18762572,¬†25584008). ClinVar contains an entry for this variant (Variation ID: 12384). This variant is present in population databases (rs121912667, ExAC 0.002%). This sequence change replaces glutamic acid with valine at codon 285 of the TP53 protein (p.Glu285Val). The glutamic acid residue is highly conserved and there is a moderate physicochemical difference between glutamic acid and valine. -
