Benign Familial Juvenile Epilepsy (BFJE) is an inherited neurological disease. The disease is characterized by seizures in pups, with the age of onset around 8 weeks of age, resolving by 13 weeks. Some adult cases have been observed. There are many forms of epilepsy reported across many breeds (and mixed-breeds), and only a few have tests associated with them. It has been reported that some dogs tested as carriers for this condition have had symptoms of BFJE, and it is not known if this is due to an different, unidentified mutation or if it is possible in some cases for one copy of the mutation to cause disease. Researchers are engaged with breed clubs and owners to further understanding.
