Doença neurodegenerativa rara com início na infância ou idade adulta, caracterizada por leucodistrofia, ataxia cerebelar e deficiência cognitiva progressiva. Causada por mutações nos genes EIF2B.

## Epidemiologia e herança


## Genes associados (5)

- **EIF2B2** — Translation initiation factor eIF2B subunit beta [Disease-causing germline mutation(s) in]
  - Função: Acts as a component of the translation initiation factor 2B (eIF2B) complex, which catalyzes the exchange of GDP for GTP on eukaryotic initiation factor 2 (eIF2) gamma subunit (PubMed:25858979, PubMed
- **EIF2B5** — Translation initiation factor eIF2B subunit epsilon [Disease-causing germline mutation(s) in]
  - Função: Acts as a component of the translation initiation factor 2B (eIF2B) complex, which catalyzes the exchange of GDP for GTP on eukaryotic initiation factor 2 (eIF2) gamma subunit (PubMed:25858979, PubMed
- **EIF2B3** — Translation initiation factor eIF2B subunit gamma [Disease-causing germline mutation(s) in]
  - Função: Acts as a component of the translation initiation factor 2B (eIF2B) complex, which catalyzes the exchange of GDP for GTP on the eukaryotic initiation factor 2 (eIF2) complex gamma subunit (PubMed:2585
- **EIF2B1** — Translation initiation factor eIF2B subunit alpha [Disease-causing germline mutation(s) in]
  - Função: Acts as a component of the translation initiation factor 2B (eIF2B) complex, which catalyzes the exchange of GDP for GTP on eukaryotic initiation factor 2 (eIF2) gamma subunit (PubMed:25858979, PubMed
- **EIF2B4** — Translation initiation factor eIF2B subunit delta [Disease-causing germline mutation(s) in]
  - Função: Acts as a component of the translation initiation factor 2B (eIF2B) complex, which catalyzes the exchange of GDP for GTP on eukaryotic initiation factor 2 (eIF2) gamma subunit (PubMed:25858979, PubMed
