Submissions by phenotype
Hirschsprung disease, susceptibility to, 1 Uncertain:2
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Multiple endocrine neoplasia, type 2 Uncertain:2
This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 210 of the RET protein (p.Glu210Lys). This variant is present in population databases (no rsID available, gnomAD 0.001%). This missense change has been observed in individual(s) with colorectal cancer and/or Hirschsprung disease (PMID: 22648184, 32283892). ClinVar contains an entry for this variant (Variation ID: 405554). 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.
This missense variant replaces glutamic acid with lysine at codon 210 of the RET protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals with colorectal cancer or Hirschsprung disease (PMID: 22648184, 32283892). This variant has been identified in 1/206144 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.
not provided Uncertain:2
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in an individual with Hirschsprung disease and in an individual with colorectal cancer (Carter et al., 2012; Erdem et al., 2020); This variant is associated with the following publications: (PMID: 14633923, 22648184, 32283892)
not specified Uncertain:1
Variant summary: RET c.628G>A (p.Glu210Lys) results in a conservative amino acid change located in the Cadherin-like (IPR002126) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 174788 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.628G>A has been reported in the literature in individuals affected with Hirschsprungs disease (Carter_2012) or colorectal cancer (Erdem_2020). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 wand all laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.

Pheochromocytoma Uncertain:1

It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system.

RET-related disorder Uncertain:1
The RET c.628G>A variant is predicted to result in the amino acid substitution p.Glu210Lys. This variant was reported in an individual with Hirschsprung disease (Carter et al. 2012. PubMed ID: 22648184) and in an individual with colorectal cancer (Erdem et al. 2020. PubMed ID: 32283892). This variant is reported in 0.0011% of alleles in individuals of European (non-Finnish) descent in gnomAD and is interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/405554/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
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.
