CACNA1A-related disorders
Pathogenic variants (mutations) in the CACNA1A gene cause a range of neurological and developmental disorders, including epilepsy (mild to severe), episodic ataxia (periods of unsteadiness and poor balance), hemiplegic migraines (a rare and severe type of migraine that involves weakness or paralysis on one side of the body), atypical eye movements, developmental delays, and autism spectrum disorder. Symptoms and severity can vary widely depending on the specific CACNA1A variant an individual has.
Clinical summary of our registry
What are CACNA1A-related disorders?
This 6-minute video on CACNA1A helps families learn about these disorders in plain language. You’ll learn:
- Scientific terms (such as genes, proteins, and variants/mutations) that will help you understand CACNA1A-related disorders
- What causes CACNA1A-related disorders
- How CACNA1A-related disorders are diagnosed
- The symptoms of CACNA1A-related disorders
- Where to find support

Portal version 1.1
The CACNA1A Portal is a coalition of investigators seeking to aggregate and harmonize data generated to study CACNA1A-related disorders, and to make summary data interactively accessible for the wider scientific community, while providing educational resources for everyone. The goals of this project are:
- Providing information on CACNA1A-related disorders
- Supporting research on CACNA1A-related disorders
- Facilitating recruitment of individuals to the global CACNA1A registries
- Providing support in variant interpretation and classification
- Visualizing data from the global CACNA1A registries
- Linking researchers, clinicians and families
