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]

Variant summary: RET c.2944C>T (p.Arg982Cys) results in a non-conservative amino acid change located in the serine-threonine/tyrosine-protein kinase, catalytic domain (IPR001245) 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 0.019 in 251460 control chromosomes in the gnomAD database, including 78 homozygotes. The observed variant frequency is approximately 1299 fold of the estimated maximal expected allele frequency for a pathogenic variant in RET causing Multiple Endocrine Neoplasia Type 2/Hirschsprung Disease phenotype (1.5e-05), strongly suggesting that the variant is benign. c.2944C>T has been reported in the early literature predating large control datasets in individuals reportedly affected with Multiple Endocrine Neoplasia Type 2/Hirschsprung Disease. These report(s) do not provide unequivocal conclusions about association of the variant with Multiple Endocrine Neoplasia Type 2/Hirschsprung Disease with no evidence supporting a damaging outcome in subsequent literature relating to this specific variant. At-least two co-occurrences with other pathogenic variant(s) have been reported (RET c.1852T>C, p.Cys618Arg; RET c.2410G>A, p.Val804Met), providing supporting evidence for a benign role (Mulligan_1994, and Lesueur_2005). At least one publication reports experimental evidence evaluating an impact on protein function. These results showed no damaging effect of this variant Pasini_1995. Nine clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (benign, n=7, likely benign, n=1, VUS, n=1). Based on the evidence outlined above, the variant was classified as benign. -

This alteration is classified as 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. -
