The threonine at codon 125 is replaced by alanine, an amino acid with similar properties. This alteration is in the DNA binding domain of the TP53 protein and is reported to have partial loss of transactivation capacity; it has been reported as a somatic mutation once but not as a germline mutation by the IARC TP53 database (Petitjean A et al. IARC TP53 database [version R17, November 2013]. Hum Mutat. 2007 Jun;28(6):622-9; Kato S et al. Proc Natl Acad Sci USA. 2003 Jul 8;100(14):8424-9). This alteration has been shown to reduce DNA binding activity (Zupnick A and Prives C. J Biol Chem. 2006 Jul 21;281(29):20464-73). 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 6503 samples (13006 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 125000 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 deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of p.T125A remains unclear. (less)
