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.2348A>C; p.Asn783Thr variant (rs587778656), to our knowledge, has not been described in the medical literature but has been reported as a variant of uncertain significance by multiple laboratories in ClinVar (Variation ID: 135178) and is observed in the general population at a low overall frequency of 0.002% (5/246198 alleles) in the Genome Aggregation Database. Additionally, another variant at this codon (c.2348A>G; p.Asn783Ser) has been detected in individuals affected with Hirschsprung disease and medullary thyroid cancer (Lebeault 2017, So 2011). The asparagine at codon 783 is highly conserved and computational algorithms (SIFT, PolyPhen2) predict that this variant is deleterious. However, due to limited information regarding this variant, its clinical significance cannot be determined with certainty. References: Lebeault M et al.

Collection Method: clinical testing

This sequence change replaces asparagine, which is neutral and polar, with threonine, which is neutral and polar, at codon 783 of the RET protein (p.Asn783Thr). This variant is present in population databases (rs587778656, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with RET-related conditions. ClinVar contains an entry for this variant (Variation ID: 135178). 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: no assertion criteria provided

Collection Method: clinical testing

The RET c.2348A>C variant is predicted to result in the amino acid substitution p.Asn783Thr. To our knowledge, this variant has not been reported in the literature in association with disease. This variant is reported in 0.0044% of alleles in individuals of European (Non-Finnish) descent in gnomAD. It has conflicting interpretations of likely benign and uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/135178/). An alternate variant at the same amino acid position has been reported in a patient with Hirschsprung disease (p.Asn783Ser; So et al. 2011. PubMed ID: 22174939). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

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. -
