Benign familial infantile seizure (BFIS) is an autosomal dominant disease characterized by focal seizures, occurring mostly in clusters, and usually first seen between 4 and 8 months of life. Psychomotor development is normal, and seizures usually resolve within the first year of life. PRRT2 has been identified as the major gene found to be mutated in 80 to 90% of cases. Recently, mutations in the genes coding for the voltage-gated sodium channel subunits have been reported.

Myoclonus (MYOCL) is characterized by sudden, brief involuntary movements. It can be severely debilitating. Myoclonus is thought to arise from spinal, subcortical, or cortical neuronal hyperexcitability. Several underlying genetic causes of familial myoclonus have been identified.

Entry
H02980 Disease
Name
Cognitive impairment with or without cerebellar ataxia
Description
Cognitive impairment with or without cerebellar ataxia (CIAT) is a rare genetic neurological disorder characterized by motor and cognitive deficits of variable expressivity. This disease is caused by mutations of the SCN8A gene, which encodes the voltage-gated sodium channel Nav1.6.
