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 valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 871 of the RET protein (p.Val871Ile). This variant is present in population databases (rs145170911, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with medullary thyroid carcinoma (PMID: 31510104). ClinVar contains an entry for this variant (Variation ID: 41842). 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. -

Variant summary: RET c.2611G>A (p.Val871Ile) results in a conservative amino acid change located in the Protein kinase domain (IPR000719) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8.4e-05 in 250112 control chromosomes. The observed variant frequency is approximately 2-fold of the estimated maximal expected allele frequency for a pathogenic variant in RET causing Multiple Endocrine Neoplasia Type 2 phenotype (3.7e-05), strongly suggesting that the variant is benign. c.2611G>A has been reported in the literature in individuals affected with hereditary medullary thyroid carcinoma, breast cancer, congenital anomalies of the kidney and urinary tract, and atherosclerosis, with no strong evidence for causality (example, Elisei_2019, Guindalini_2022, Hwang_2014, Johnston_2012). These report(s) do not provide unequivocal conclusions about association of the variant with Multiple Endocrine Neoplasia Type 2. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 31510104, 35264596, 24429398, 22703879). Nine submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 (VUS, n=8, Benign, n=1). Based on the evidence outlined above, the variant was classified as likely benign. -
