-
A rare genetic neuronal ceroid lipofuscinosis disorder with characteristics of infantile to early childhood onset of progressive myoclonic seizures (occasionally accompanied by generalised tonic-clonic seizures) and severe progressive neurological regression, leading to psychomotor and cognitive decline, cerebellar ataxia, dementia and, frequently, early death. Vision loss may be associated. EEG typically reveals epileptiform activity with predominance in the posterior region and photosensitivity. Caused by homozygous or compound heterozygous mutation in the KCTD7 gene on chromosome 7q11.
