What is the CACNA1E?
The CACNA1E gene codes for a subunit of the voltage-gated calcium channel, which plays an important role in cells of the nervous system, the heart muscle and other tissues. This calcium channel is crucial for the regulation of calcium ion currents, which are necessary for the transmission and processing of excitation in the cells. Mutations in the CACNA1E gene can lead to a rare genetic disorder associated with neurological and muscular symptoms. These include frequent epileptic seizures, movement disorders such as ataxia and muscle weakness as well as delayed mental and motor development. In some cases, behavioral abnormalities such as autism spectrum disorders also occur. The disease belongs to the group of channelopathies in which defects in ion channels disrupt normal cell function. Treatment focuses primarily on controlling the symptoms, especially the seizures, and is usually carried out with special medication.
Tools that are frequently used with CACNA1E:
Aids and support for everyday life
In order to ensure safety and promote the child's participation, it is crucial to provide individually adapted aids for CACNA1E syndrome:
- Safety in epilepsy: due to the risk of falling during seizures, safety helmets are often essential for daytime use. At night, epilepsy sensor mats or special wearables offer safety to register seizures immediately.
- Mobility & stability: In the case of gait instability (ataxia), specialized walkers or rollators help to give the child stability. For more severe muscle weakness, active wheelchairs or rehab buggies with anatomical seat shells provide support.
- Positioning: An adapted therapy chair supports correct posture when eating and playing, which is particularly important for hypotonic trunk muscles.
- Augmentative and Alternative Communication (AAC): If speech development is delayed, talkers, tablets with communication apps or symbol cards help to break down barriers.
- Sensory relief: In the case of autism symptoms or sensory hypersensitivity, weighted blankets can help to calm the nervous system and improve sleep.
