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]

This missense variant replaces aspartic acid with asparagine at codon 567 of the RET protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). A functional study has reported that this variant causes ectopic RET dimerization, activation of kinase activity and tumor formation in murine allograft growth assay (PMID: 36166639). This variant has been reported in a fetus affected with renal agenesis and an unaffected parent and in a Latina individual affected with adrenal medullary hyperplasia (PMID: 21490379, 32732076). This variant has been identified in 46/282764 chromosomes in the general population, including 22/35434 chromosomes in the Latino 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 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). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

The RET c.1699G>A (p.Asp567Asn) missense change has a maximum subpopulation frequency of 0.062% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). This variant occurs in the extracellular calmodulin-like motif (CaLM) in the cysteine rich domain, recently described as the location of a novel 3D cluster of oncogenic mutations in RET (PMID: 36166639). The in silico tool REVEL predicts a deleterious effect on protein function, and a molecular dynamics assay of mutations in CaLM and showed that this variant affects the conformational integrity of the RET-Ca2+ ion complex, underlying oncogenic properties which are increased in the presence of ligands/co-receptors that facilitate dimerization (PMID: 36166639). An in-vivo study showed that this variant is potentially druggable after existing RET-TKIs drugs, selpercatinib and pralsetinib, were shown to suppress the growth of NIH3T3 cells expressing p.Asp567Asn similar to their effect on NIH3T3 cells expressing known pathogenic mutations (PMID: 36166639). To our knowledge, this variant has not been reported in the literature in individuals with multiple endocrine neoplasia type IIA or type IIB. 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. -
