Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2
The NM_020975.6(RET):c.1009G>A(p.Glu337Lys) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E337Q) has been classified as Uncertain significance.

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]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 18, 2023 | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 337 of the RET protein (p.Glu337Lys). This variant is not present in population databases (gnomAD no frequency). 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: 432780). 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 tolerated. 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. - |

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jun 19, 2017 | The E337K variant in the RET gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The E337K variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The E337K variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved in mammals. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret E337K as a variant of uncertain significance. - |
