Submissions by phenotype
Hereditary cancer-predisposing syndrome Uncertain:2Benign: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. -
- -
not provided Uncertain:2
- -
In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with medullary thyroid carcinoma, Hirschsprung's disease, and breast cancer (Carter et al., 2012; Amosenko et al., 2018; Chen et al., 2020); This variant is associated with the following publications: (PMID: 31159747, 28946813, 14633923, 32091409, Amosenko2018[casereport], 22648184) -

Multiple endocrine neoplasia, type 2 Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 886 of the RET protein (p.Arg886Gln). This variant is present in population databases (rs373594744, gnomAD 0.03%). This missense change has been observed in individual(s) with Hirschsprung disease, medullary thyroid cancer, and/or pheochromocytoma (PMID: 22648184, 28946813, 33981013). ClinVar contains an entry for this variant (Variation ID: 543745). 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 disruptive. 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. -
Multiple endocrine neoplasia type 2A Benign:1
This variant is considered likely benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. -
