Genes linked to Dysembryoplastic neuroepithelial tumor
MUTYH: Adenine DNA glycosylase
It removes adenines incorrectly paired with oxidized guanine, preventing characteristic G:C-to-T:A mutations during base-excision repair. Biallelic loss-of-function variants cause MUTYH-associated polyposis and substantially increase colorectal-cancer risk.
1 disease-causing and 0 uncertain variants in MUTYH are linked to Dysembryoplastic neuroepithelial tumor.
Weakly linked (only a few uncertain records): FGFR1.
Known disease-causing variants in Dysembryoplastic neuroepithelial tumor
| Variant | Position | Protein part | Clinical label |
|---|---|---|---|
| MUTYH Y176C | 176 | Disease-causing (★★) |
Same protein, different disease
- Familial adenomatous polyposis is also caused by MUTYH variants; they fall mostly in different places as the Dysembryoplastic neuroepithelial tumor variants (27 disease-causing).
- Gastric cancer is also caused by MUTYH variants; they fall mostly in different places as the Dysembryoplastic neuroepithelial tumor variants (11 disease-causing).

How many genetic variants are linked to Dysembryoplastic neuroepithelial tumor?
5 variants: 1 are classified as disease-causing (pathogenic or likely pathogenic) in ClinVar and 0 are of uncertain significance or have conflicting reports.
Which uncertain variants in Dysembryoplastic neuroepithelial tumor look disease-causing?
None of the uncertain variants currently reaches the likely-pathogenic range on computable evidence alone.
About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
