What are the genetic changes related to autosomal dominant partial epilepsy with auditory features ?
Mutations in the LGI1 gene cause ADPEAF. This gene provides instructions for making a protein called Lgi1 or epitempin, which is found primarily in nerve cells (neurons) in the brain. Although researchers have proposed several functions for this protein, its precise role in the brain remains uncertain.  Mutations in the LGI1 gene likely disrupt the function of epitempin. It is unclear how the altered protein leads to seizure activity in the brain.  LGI1 mutations have been identified in about half of all families diagnosed with ADPEAF. In the remaining families, the cause of the condition is unknown. Researchers are searching for other genetic changes that may underlie the condition.
