Abstract:
Objective To study the clinical and genetic features of familial paroxysmal kinesigenic dyskinesias (PKD). Methods The clinical information of PKD patients from 3 Han families was analyzed and the pedigrees were further investigated. Results There were 25 PKD cases in 3 families, including 16 males and 9 females. The onset age ranged from 1 to 10 years. The attacks were provoked by voluntary movements and each attack lasted less than 30 seconds with no loss of consciousness. No neurological signs and abnormal examination were detected during the intermittent period. There were 10 to 50 attacks per day, but the frequency commonly decreased with the increase of age. The attacks can be controlled by carbamazepine. The disease was inherited in an autosomal dominant mode. Males were affected more severely than females. Conclusions The main inheritance mode of familial PKD is autosomal dominant. There may be clinic or genetic heterogeneity.
