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]

Submissions by phenotype

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The p.V997L variant (also known as c.2989G>C), located in coding exon 18 of the RET gene, results from a G to C substitution at nucleotide position 2989. The valine at codon 997 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on data from gnomAD, the frequency for this variant is above the maximum credible frequency for a MEN2-causing variant in this gene based on internally established thresholds (Karczewski et al. Nature. 2020 May;581(7809):434-443; Whiffin et al. Genet Med. 2017 10;19:1151-1158). Based on the supporting evidence, this association with Hirschsprung disease is unknown; however, the association of this alteration with MEN2 is unlikely. -

Multiple endocrine neoplasia, type 2 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 01, 2022In 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 477361). This variant has not been reported in the literature in individuals affected with RET-related conditions. This variant is present in population databases (rs781236624, gnomAD 0.006%). This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 997 of the RET protein (p.Val997Leu). -
