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 sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 59 of the RET protein (p.Ala59Thr). This variant is present in population databases (rs376565365, gnomAD 0.02%). 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: 423343). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

This variant is denoted RET c.175G>A at the cDNA level, p.Ala59Thr (A59T) at the protein level, and results in the change of an Alanine to a Threonine (GCC>ACC). This variant has not, to our knowledge, been published in the literature as a pathogenic or benign germline variant. RET Ala59Thr was not observed at a significant allele frequency in large population cohorts (Lek 2016). This variant is located in the extracellular cadherin domain (Garcia-Barcel? 2004). In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether RET Ala59Thr is a pathogenic or benign variant. We consider it to be a variant of uncertain 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. -
