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]

Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 10, 2024This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 398 of the WRAP53 protein (p.Arg398Trp). This variant is present in population databases (rs281865548, gnomAD 0.3%). This missense change has been observed in individual(s) with clinical features of Hoyeraal Hreidarsson syndrome or dyskeratosis congenita (PMID: 21205863, 32303682). ClinVar contains an entry for this variant (Variation ID: 30975). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects WRAP53 function (PMID: 21205863, 32303682). 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. -
