Question: Is autosomal dominant nocturnal frontal lobe epilepsy inherited ?
Answer: This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to raise the risk of developing epilepsy. About 70 percent of people who inherit a mutation in the CHRNA2, CHRNA4, or CHRNB2 gene will develop seizures. In most cases, an affected person has one affected parent and other relatives with the condition. Other cases are described as sporadic, which means an affected person has no family history of the disorder.
