CNTN2_HUMAN
  • Epilepsy, familial adult myoclonic, 5 (FAME5) [MIM:615400]: A form of familial myoclonic epilepsy, a neurologic disorder characterized by cortical hand tremors, myoclonic jerks and occasional generalized or focal seizures with a non-progressive or very slowly progressive disease course. Usually, myoclonic tremor is the presenting symptom, characterized by tremulous finger movements and myoclonic jerks of the limbs increased by action and posture. In a minority of patients, seizures are the presenting symptom. Some patients exhibit mild cognitive impairment. FAME5 is characterized by onset of seizures in adolescence, followed by the development of cortical myoclonic tremor later in life. Inheritance is autosomal recessive. {ECO:0000269 PubMed:23518707}. Note=The disease is caused by mutations affecting the gene represented in this entry.
