Two cases of familial hypokalemic periodic paralysis in Negro brothers occurred, and--because this has been reported to be an unusual disease among blacks--the family pedigree was investigated. Histories were obtained on 79 family members in four generations. Twenty seven (34%) had symptoms of periodic paralysis or weakness. As far as we could determine, there were no Caucasian ancestors.
两名黑人兄弟患家族性低钾性周期性麻痹，鉴于该病在黑人中鲜有报道，遂对其家族谱系展开调查。获取了四代79名家族成员的病史。其中27人（34%）有周期性麻痹或肌无力症状。据我们所知，其家族并无白人祖先。
