基因产物:原钙粘蛋白19。

蛋白功能:主要在脑内表达,属于钙依赖性细胞粘附蛋白。

相关疾病:发育性癫痫性脑病9型(也有称做限于女性的癫痫和智力低下(epilepsy and mental retardation restricted to females,EFMR),注:只是多数仅累及女性,也有男性发病的报道(嵌合体发病),可表现为 热性惊厥附加症,遗传性癫痫伴热性惊厥附加症 Dravet 综合征 婴儿癫痫伴游走性局灶性发作 )(XL)[1-4]。

相关临床研究:PubMed数据库(PMID:  32057594 (Pediatr Neurol. 2020) ; PMID: 30451291 (Epilepsia. 2018)

用药提醒 PMID: 26820223(Seizure. 2016) 曾对58名具有PCDH19基因突变的女性患者的抗癫痫药物有效性进行分析,认为最有效的药物为 氯巴占 (样本量尚小,仅供参考,且有些药物未包括)
