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]

Multiple endocrine neoplasia, type 2 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingAll of Us Research Program, National Institutes of HealthAug 28, 2023This missense variant replaces glycine with arginine at codon 423 of the RET protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with Hirschsprung disease (PMID: 21995290, 22174939). This variant has been identified in 2/250476 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 08, 2023This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 423 of the RET protein (p.Gly423Arg). This variant is present in population databases (rs767601598, gnomAD 0.003%). This missense change has been observed in individual(s) with Hirschsprung disease (PMID: 21995290, 22174939). ClinVar contains an entry for this variant (Variation ID: 548849). 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. 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. -

Uncertain significance, criteria provided, single submitterclinical testingGeneDxMay 31, 2022Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; In silico analysis, which includes splice predictors and evolutionary conservation, suggests this variant may also impact gene splicing, but in the absence of RNA/functional studies, the actual effect of this sequence change is unknown; This variant is associated with the following publications: (PMID: 21995290, 28179590, 24241536, 22174939) -
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2023The p.G423R variant (also known as c.1267G>A), located in coding exon 7 of the RET gene, results from a G to A substitution at nucleotide position 1267. The glycine at codon 423 is replaced by arginine, an amino acid with dissimilar properties. This variant has been reported in two individuals with Hirschsprung disease (So MT, PLoS ONE 2011 ; 6(12):e28986 and Núñez-Torres R, BMC Med. Genet. 2011 ; 12:138). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
