Genes affected

RET (HGNC:9967): (ret proto-oncogene) This gene encodes a transmembrane receptor and member of the tyrosine protein kinase family of proteins. Binding of ligands such as GDNF (glial cell-line derived neurotrophic factor) and other related proteins to the encoded receptor stimulates receptor dimerization and activation of downstream signaling pathways that play a role in cell differentiation, growth, migration and survival. The encoded receptor is important in development of the nervous system, and the development of organs and tissues derived from the neural crest. This proto-oncogene can undergo oncogenic activation through both cytogenetic rearrangement and activating point mutations. Mutations in this gene are associated with Hirschsprung disease and central hypoventilation syndrome and have been identified in patients with renal agenesis. [provided by RefSeq, Sep 2017]

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 313 of the RET protein (p.Arg313Trp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Hirschsprung disease (PMID: 21995290, 23372769). ClinVar contains an entry for this variant (Variation ID: 381593). 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. 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. -

The p.R313W variant (also known as c.937C>T), located in coding exon 5 of the RET gene, results from a C to T substitution at nucleotide position 937. The arginine at codon 313 is replaced by tryptophan, an amino acid with dissimilar properties. This variant has been previously reported in Spanish individuals with Hirschsprung disease (Núñez-Torres et al., BMC Med. Genet. 2011 Oct;12:138; Luzón-Toro B et al. PLoS ONE, 2013 Jan;8:e54800). This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
