简要总结
The prevalence of CTX in our country is estimated to be 1 / 50.000. The aim of this study is to screen more volunteers by conducting a larger screening from neurology and pediatric metabolism clinics in Turkey.
This observational study was designed retrospectively and prospectively in two stages. In the retrospective section, the patient database and / or patient files will be screened in the neurology and pediatric metabolism clinics and the patients aged 40 and below in the neurology clinics with at least two of the following will be enrolled to the study:
- Ataxia and / or spasticity
- Bilateral cataract (except senile cataract)
- Intellectual limitation
- Non-enhancing hyperintensity on T2 sections in MR imaging of dentate nuclei
- Autosomal recessive transition pattern. (Ex: Relative Marriage)
In the pediatric metabolism centers, cases suspected of CTX and planned to apply the Mignarri Index according to the investigator's opinion will be identified.

- •Patients in neurology clinics should have been identified with at least two of the following:
- •Ataxia and / or spasticity
- •Bilateral cataract (except senile cataract)
- •Intellectual limitation
- •Nonintensitive hyperintensity in T2 sections on MRI of the dentate nucleus

排除标准
- •The patient's ataxia and / or spasticity, cataract, intellectual limitation, and non-contrasted hyperintensity of T2 sections in MR imaging of dentate nuclei with typical MRI findings are due to a known cause other than CTX or other underlying disease.
