What gene is responsible for epilepsy?
The most common epilepsy genes were ion-channel genes, which account for 28 of the 84 epilepsy genes, indicating that ion-channel genes may play an important role in epilepsy….3.1. Epilepsy genes.
|Phenotype (in order of the onset age)||Inheritance||Gene|
|Familial temporal lobe epilepsy (FTLE)||AD||CPA6, GAL, LGI1|
What chromosome is epilepsy found on?
Ring chromosome 20 syndrome is a condition that affects the normal development and function of the brain. The most common feature of this condition is recurrent seizures (epilepsy) in childhood. The seizures may occur during the day or at night during sleep.
What genetic syndromes cause temporal lobe epilepsy?
Temporal lobe epilepsy is usually caused by a problem such as mesial temporal sclerosis. However, familial temporal lobe epilepsy is a genetic condition with autosomal dominant inheritance.
What is the heritability of epilepsy?
Twin studies suggest that the heritability of epilepsy is ~25%–70% and appears to increase with age. Studies have shown that the probandwise concordance rate is 0.37 in monozygotic twins, which is significantly higher than that in dizygotic twins. 8.
What are the main causes of epilepsy?

- a stroke.
- a brain tumour.
- a severe head injury.
- drug abuse or alcohol misuse.
- a brain infection.
- a lack of oxygen during birth.
What causes temporal lobe seizures?
Often, the cause of temporal lobe seizures remains unknown. However, they can be a result of a number of factors, including: Traumatic brain injury. Infections, such as encephalitis or meningitis, or a history of such infections.
Where is the temporal area?
The temporal lobes sit behind the ears and are the second largest lobe. They are most commonly associated with processing auditory information and with the encoding of memory.
Can epilepsy be passed from mother to child?
If the mother has epilepsy and the father does not, the risk is still less than 5 in 100. If both parents have epilepsy, the risk is a bit higher. Most children will not inherit epilepsy from a parent, but the chance of inheriting some types of epilepsy is higher.
What is the main cause of epilepsy?
Epilepsy has no identifiable cause in about half the people with the condition. In the other half, the condition may be traced to various factors, including: Genetic influence. Some types of epilepsy, which are categorized by the type of seizure you experience or the part of the brain that is affected, run in families.
