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 significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Jul 24, 2023	The p.N361K variant (also known as c.1083C>A), located in coding exon 6 of the RET gene, results from a C to A substitution at nucleotide position 1083. The asparagine at codon 361 is replaced by lysine, an amino acid with similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on data from gnomAD, the frequency for this variant is above the maximum credible frequency for a MEN2 disease-causing variant in this gene based on internally established thresholds (Karczewski et al. Nature. 2020 May;581(7809):434-443; Whiffin et al. Genet Med. 2017 10;19:1151-1158). Based on the supporting evidence, the association of this alteration with Hirschsprung disease is unknown; however, the association of this alteration with MEN2 is unlikely. -

DNA sequence analysis of the RET gene demonstrated a sequence change, c.1083C>A, in exon 6 that results in an amino acid change, p.Asn361Lys. This sequence change has been described in the gnomAD database with a frequency of 0.005% in the European sub-population (dbSNP rs770587835). The p.Asn361Lys change has been reported in an individual with Hirschsprung disease (PMID: 10790203). Functional studies have demonstrated that RET protein folding and cellular localization is impacted in the presence of this sequence change (PMID: 12915470, 26517685). The p.Asn361Lys change affects a poorly conserved amino acid residue located in a domain of the RET protein that is known to be functional. The p.Asn361Lys substitution appears to be benign using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). Due to these contrasting evidences, the clinical significance of the p.Asn361Lys change remains unknown at this time. -

This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 361 of the RET protein (p.Asn361Lys). This variant is present in population databases (rs770587835, gnomAD 0.004%). This missense change has been observed in individual(s) with Hirschsprung disease and/or osteosarcoma (PMID: 10790203, 32179705). ClinVar contains an entry for this variant (Variation ID: 548864). 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. Experimental studies have shown that this missense change affects RET function (PMID: 12915470, 26517685). 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. -

In silico analysis supports that this missense variant does not alter protein structure/function; Published functional studies are inconclusive: abnormal protein folding and RET protein localization, but with ubiquitination levels close to wildtype (Kjaer et al., 2003; Jori et al., 2015); This variant is associated with the following publications: (PMID: 14633923, 12915470, 10790203, 26517685, 32179705) -

The RET c.1083C>A variant is predicted to result in the amino acid substitution p.Asn361Lys. This variant has previously been reported in patients with variable and possibly RET-related phenotypes (including Hirschsprung, osteosarcoma, and Lynch syndrome), and some functional studies support its pathogenicity (Hofstra et al. 2000. PubMed ID: 10790203; Kjaer et al. 2003. PubMed ID: 12915470; Kovac et al. 2020. PubMed ID: 32179705; Jóri et al. 2015. PubMed ID: 26517685). This variant is reported in 0.0047% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/10-43604498-C-A) and is interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/548864/?new_evidence=true). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
