Multiple endocrine neoplasia, type 2 Uncertain:2
This missense variant replaces arginine with histidine at codon 417 of the RET protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RET-related disorders in the literature. This variant has been identified in 12/250150 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 417 of the RET protein (p.Arg417His). This variant is present in population databases (rs201030628, gnomAD 0.006%). 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: 405555). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
not provided Uncertain:2
The RET c.1250G>A (p.Arg417His) variant has been reported in the published literature in an individual with Hirschsprung disease (PMID: 29261189 (2018)). The frequency of this variant in the general population, 0.000062 (7/113188 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -
In silico analysis indicates that this missense variant does not alter protein structure/function; Observed in an individual with Hirschsprung disease (PMID: 29261189); This variant is associated with the following publications: (PMID: 14633923, 25733075, 29219214, 24336963, 29261189) -
Hereditary cancer-predisposing syndrome Benign:1
This alteration is classified as likely 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. -
