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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Genetic Services Laboratory, University of Chicago	May 04, 2020	DNA sequence analysis of the RET gene demonstrated a sequence change, c.785T>C, in exon 4 that results in an amino acid change, p.Val262Ala. This sequence change has been described in the gnomAD database with a frequency of 0.043% in the South Asian sub-population (dbSNP rs139790943). The p.Val262Ala change has been reported in an individual with Hirshsprung's disease (PMID: 11955539). The p.Val262Ala change affects a moderately conserved amino acid residue located in a domain of the RET protein that is known to be functional. The p.Val262Ala substitution appears to be deleterious based on in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). Due to the lack of functional studies, the clinical significance of the p.Val262Ala change remains unknown at this time. -
Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Jan 24, 2017	Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant is present in HGMD in 4 papers, with comments suggesting VUS. It has been seen in unaffected patients, as well as one with Hirschprung's disease and an individual with pituitary adenomas but did not segregate in this family. This variant has a Max MAF of 0.032% in ExAC. It is classified with 2 stars as VUS by GeneDx, Invitae, Biesecker, and CSER_CC_NCGL. -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 262 of the RET protein (p.Val262Ala). This variant is present in population databases (rs139790943, gnomAD 0.04%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with non-medullary thyroid carcinoma and Hirschsprung disease (PMID: 11955539, 31614935). ClinVar contains an entry for this variant (Variation ID: 41845). 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. -
