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 arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 886 of the RET protein (p.Arg886Gln). This variant is present in population databases (rs373594744, gnomAD 0.03%). This missense change has been observed in individual(s) with Hirschsprung disease, medullary thyroid cancer, and/or pheochromocytoma (PMID: 22648184, 28946813, 33981013). ClinVar contains an entry for this variant (Variation ID: 543745). 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 disruptive. 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. -
