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]

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

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 136 of the RET protein (p.Glu136Lys). This variant is present in population databases (rs79014735, gnomAD 0.03%). 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: 216727). 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 glutamic acid with lysine at codon 136 of the RET protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RET-related disorders in the literature, but was identified in a healthy control individual (PMID: 29641532). This variant has been identified in 22/251406 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: no assertion criteria provided
Collection Method: clinical testing

The RET c.406G>A variant is predicted to result in the amino acid substitution p.Glu136Lys. This variant has been reported in a breast cancer specimen from the The Cancer Genome Atlas (TGCA; Table S9, Yehia et al. 2018. PubMed ID: 29684080). This variants has been reported in a control individual from a cutaneous melanoma cohort study (Supplement, Pritchard et al. 2018. PubMed ID: 29641532). This variant is reported in 0.032% of alleles in individuals of Latino descent in gnomAD. It is interpreted as uncertain significance by the vast majority of submitters in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/216727/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

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. -
