SLC13A5 deficiency (Citrate Transporter Disorder, EIEE 25) is a rare genetic disorder with neurodevelopmental delays and seizure onset in the first few days of life. This natural history study is designed to address the lack of understanding of disease progression. Additionally it will identify clinical and biomarker endpoints for use in future clinical trials.
This is a longitudinal observational study of the natural history of SLC13A5 deficiency for up to 2 years. This study does not involve any therapeutic intervention. The study includes in-person clinical assessments and laboratory analyses including standardized clinical evaluations, neurocognitive and quality of life scales, video movement rating scale, laboratory measurements of blood and urine, EEG capturing wake and sleep, EKG. Additionally, remote assessments in 1st year (every 3 months) and 2nd year (every 4 months) of enrollment will be made and caregiver will be asked to keep a seizure…
Inclusion Criteria: 1. Parent(s)/legal representative and/or patient must be willing and able to give informed consent/assent for participation in the study. 2. Males and females of any age are eligible for this study 3. Suspected or confirmed diagnosis of SLC135 deficiency with genetic variants in both SLC13A5 alleles and consistent clinical characteristics. Variants of uncertain significance in one or both alleles are acceptable if deemed good candidates by participant's primary geneticist or neurologist and study personnel. 4. Participant and caregiver must be willing to provide clinical d…
