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]

The RET c.2371T>A (p.Tyr791Asn) missense change has a maximum subpopulation frequency of 0.009% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a deleterious effect on protein function, but this prediction has not been confirmed by functional studies. This variant has been reported in individuals with c-cell hyperplasia, medullary thyroid cancer, and Hirschsprung disease, but has also been reported in unaffected individuals (PMID: 14557476, 17108762, 25425582, 28946813). 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. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces tyrosine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 791 of the RET protein (p.Tyr791Asn). This variant is present in population databases (rs377767417, gnomAD 0.008%). This missense change has been observed in individual(s) with Hirschsprung disease and medullary thyroid cancer (PMID: 14557476, 17108762, 20013610, 23259706, 25425582, 26559152, 28946813). ClinVar contains an entry for this variant (Variation ID: 24939). 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 tolerated. 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. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This missense variant replaces tyrosine with asparagine at codon 791 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 two individuals affected with medullary thyroid carcinoma (PMID: 23259706, 28946813), one of these individuals also carried a known pathogenic variant in the RET gene that could explain the observed phenotype (PMID: 23259706). This variant has also been reported in individuals affected with Hirschsprung disease (PMID: 17108762, 26559152) and several unaffected individuals (PMID: 14557476, 20013610, 25425582). This variant has been identified in 13/282514 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. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

DNA sequence analysis of the RET gene demonstrated a sequence change, c.2371T>A, in exon 13 that results in an amino acid change, p.Tyr791Asn. This sequence change has been described in the gnomAD database with a frequency of 0.009% in the non-Finnish European subpopulation (dbSNP rs377767417). The p.Tyr791Asn change affects a highly conserved amino acid residue located in a domain of the RET protein that is known to be functional. The p.Tyr791Asn substitution appears to be deleterious using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). This sequence change has been previously described in individuals with medullary thyroid cancer and Hirschsprung disease as well as individuals without disease (PMID: 25425582, 20013610, 17108762, 21479187, 26559152, 14557476, 23259706, 28946813). Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.Tyr791Asn change remains unknown at this time. -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
