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]

The RET c.341G>A variant is predicted to result in the amino acid substitution p.Arg114His. This variant has been described as a recurrent variant in individuals with Hirschprung disease and Chinese ancestry, although it has also been found in unaffected parents (Garcia-Barceló et al. 2004. PubMed ID: 14633923; Cornes et al. 2010. PubMed ID: 20532249). This variant has also been described in presumably healthy controls and is present in population databases in up to 1.0% individuals, with East Asian descent being the most prevalent (Bodian et al. 2014. PubMed ID: 24728327; Olfson et al. 2015. PubMed ID: 26332594; http://gnomad.broadinstitute.org/variant/10-43597793-G-A). This variant change resides within the Tyrosine-protein kinase, Ret receptor domain. In vitro functional characterization of this variant suggests that it does not result in loss of function, as would be expected for a pathogenic variant in Hirschsprung disease (Kjaer et al. 2010. PubMed ID: 20473317). These observations suggest that the c.314A>G (p.Arg114His) variant is possibly benign or a risk factor for Hirschsprung disease. Although we suspect that this variant may be benign, at this time, its clinical significance is uncertain due to the absence of conclusive functional and genetic information. -

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
