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).

WRAP53 (HGNC:25522): (WD repeat containing antisense to TP53) This gene encodes an essential component of the telomerase holoenzyme complex, a ribonucleoprotein complex required for telomere synthesis. This protein is enriched in Cajal bodies, nuclear sites of RNP processing that are important for telomerase function. It interacts with dyskerin, TERT and TERC, other components of active telomerase, and with small Cajal body RNAs (scaRNAs), which are involved in modifying splicing RNAs. This mRNA also functions as a p53 antisense transcript, that regulates endogenous p53 mRNA levels and further induction of p53 protein by targeting the 5' untranslated region of p53 mRNA. Alternatively spliced transcript variants which differ only in the 5' UTR have been found for this gene. [provided by RefSeq, Mar 2011]

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Apr 26, 2017 | This variant is denoted TP53 c.-42C>T and describes a nucleotide substitution 42 base pairs upstream of the TP53 ATG translational start site in the 5' untranslated region (UTR). The surrounding sequence, with the base that is substituted in brackets, is GACACG[C/T]TTCCCT. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. No data are available from control populations to assess the frequency of this variant (NHLBI Exome Sequencing Project, The 1000 Genomes Consortium 2015, Lek 2016). The cytosine (C) base that is altered is conserved across species. At this time, we consider TP53 c.-42C>T to be a variant of uncertain significance. - |
