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]

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

The RET c.1597G>A (p.Gly533Ser) missense change has a maximum subpopulation frequency of 0.029% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a deleterious effect on protein function, however functional studies performed on cell lines suggest that this variant does not affect RET function (PMID: 26395553). This variant has been reported in individuals with Hirshsprung disease (PMID: 17009072, 23084198, 26395553), hyperparathyroid disease (PMID: 32761341), and an individual with congenital anomalies of the kidney and urinary tract (PMID: 34979951). Other variant(s) that disrupt the p.Gly533 residue have been determined to be pathogenic (PMID: 14602786, 16649977, 22676047, 23461807). 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. -

Color Diagnostics, LLC DBA Color Health
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This missense variant replaces glycine with serine at codon 533 of the RET protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function. A functional study reported that this variant does not impact RET function in RET and ERK phosphorylation (PMID: 2639553). This variant has been reported in at least one individual affected with paraganglioma or pheochromocytoma (PMID: 22517557). A different missense mutation at this codon, c.1597G>T (p.Gly533Cys), is reported as disease-causing in ClinVar (Variation ID: 13950). This variant has been identified in 8/183154 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

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 533 of the RET protein (p.Gly533Ser). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with Hirschsprung disease (PMID: 22517557, 23084198, 26395553). ClinVar contains an entry for this variant (Variation ID: 24887). 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. Experimental studies have shown that this missense change does not substantially affect RET function (PMID: 26395553). This variant disrupts the p.Gly533 amino acid residue in RET. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 14602786, 16649977, 18805915, 22676047, 23461807). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 glycine with serine at codon 533 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). Functional studies have shown that this variant does not appear to result in increased RET phosphorylation (PMID: 26395553). To our knowledge, this variant has not been reported in individuals affected with MEN2A syndrome but has been reported in individuals affected with paraganglioma/pheochromocytoma (PMID: 22517557), or Hirschsprung disease (PMID: 17009072, 23084198, 26395553). This variant has been identified in 8/183154 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. -

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 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. -
