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 2A Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingSt. Jude Molecular Pathology, St. Jude Children's Research HospitalAug 30, 2023The RET c.1187C>T (p.Ser396Leu) missense change has a maximum subpopulation frequency of 0.006% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and functional studies have not been performed. This variant has been identified in an individual with Hirschsprung's disease (PMID: 22648184). This variant has not been reported in the literature in individuals with multiple endocrine neoplasia type II. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Multiple endocrine neoplasia, type 2 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeFeb 01, 2024This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 396 of the RET protein (p.Ser396Leu). This variant is present in population databases (rs781646869, gnomAD 0.006%). This missense change has been observed in individual(s) with Hirschsprung disease (PMID: 22648184). ClinVar contains an entry for this variant (Variation ID: 372081). 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. -
Uncertain significance, criteria provided, single submitterclinical testingAll of Us Research Program, National Institutes of HealthDec 01, 2023This missense variant replaces serine with leucine at codon 396 of the RET protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported as a germline variant in individuals affected with RET-related cancer in the literature. This variant has been identified in 8/282306 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. -

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2023The p.S396L variant (also known as c.1187C>T), located in coding exon 6 of the RET gene, results from a C to T substitution at nucleotide position 1187. The serine at codon 396 is replaced by leucine, an amino acid with dissimilar properties. This alteration has been reported in an individual with Hirschsprung disease (Carter TC et al. J. Hum. Genet., 2012 Aug;57:485-93). This amino acid position is 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. -
