Genes affected

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]

Significance:Uncertain significance

Collection Method:clinical testing

The WRAP53 c.893G>A; p.Arg298Gln variant (rs560038082), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 437302). This variant is found in the Admixed American population with an allele frequency of 0.08% (28/35432 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.264). A different variant at this codon, c.892C>T; p.Arg298Trp, has been reported as a homozygote in a patient with dyskeratosis congenita (Shao 2018). However, due to limited information, the clinical significance of the p.Arg298Gln variant is uncertain at this time. References: Shao Y et al. A unique homozygous WRAP53 Arg298Trp mutation underlies dyskeratosis congenita in a Chinese Han family. BMC Med Genet. 2018 Mar 7;19(1):40. PMID: 29514627 -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 298 of the WRAP53 protein (p.Arg298Gln). This variant is present in population databases (rs560038082, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with WRAP53-related conditions. ClinVar contains an entry for this variant (Variation ID: 437302). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R298Q variant (also known as c.893G>A), located in coding exon 6 of the WRAP53 gene, results from a G to A substitution at nucleotide position 893. The arginine at codon 298 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
