根据最新国际抗癫痫联盟(2022)癫痫综合征定义为PCDH19簇集性癫痫(PCDH19 Clustering Epilepsy,PCDH19CE)。 PCDH19基因定位于染色体Xq22,其编码的原钙黏蛋白19属于原钙黏蛋白δ2亚家族一员,有6个外显子。PCDH19作为细胞的黏附分子组成部分,主要表达于中枢神经系统,特别在海马和杏仁核中呈现高表达[2]。 PCDH19簇集...
PCDH19基因编码原钙黏蛋白19,参与细胞间的信号传导。1971年Juberg等[1]在一个大家系中发现仅限于女性的癫痫和智力障碍(epilepsy and mental retardation limited to females, EFMR)——15名女性(父源血亲),临床表现为癫痫伴智力低下,她们的父亲均表型正常...

遗传性X连锁早发性儿童癫痫，也被称为EFMR（epilepsy and mental retardation limited to females），属于X染色体连锁疾病。与其他X连锁疾病不同的是，EFMR的发病人群不是半合子（hemi）的男性，而是杂合子（het）的女性。只有杂合子女性才会表现为癫痫和智力低下[1, 2]，这种不同寻常的疾病在50多年来一直困扰...
2021PCDH19基因仅限于女性的癫痫和智力障碍(epilepsyandmentalretardationlimitedtof emales,EFMR)PCDH19基因的发现PCDH19基因编码原钙黏蛋白19,参与细胞间的信号传导。1971年Juberg 等在一个大家系中发现仅限于女性的癫痫和智力障碍(epilepsyandmentalretardationlimitedt ...
The PCDH19 gene (Xp22.1) encodes the cell-adhesion protein protocadherin-19 (PCDH19) and is responsible for a neurodevelopmental pathology characterized by female-limited epilepsy, cognitive impairment and autistic features, the pathogenic mechanisms of which remain to be elucidated. Here, we ...
其中,PCDH19基因突变与X染色体连锁的早期婴儿型癫痫性脑病9型(Developmental and epileptic encephalopathy 9)疾病相关,该疾病又被称为受限于女性的癫痫和智力障碍(epilepsy and mental retardation restricted to females (EFMR)),是一种仅限...
PCDH19基因编码原钙黏蛋白19,首次被Dibbens等[ 1 ]在限于女性的癫痫伴智力低下(epilepsy and mental retardation limited to females)的家系中报道,该病有着特殊的X连锁遗传方式,即携带PCDH19基因变异的女性杂合子发病,而男性半合子不发病,少数男性嵌合体可发病[ 2 ]。该基因变异导致的癫痫以女性患儿为主,多数...
Mutations in the PCDH19 gene are an important cause of early-onset epilepsy in females along the spectrum of epilepsy in females linked to mental retardation. Patients often have cognitive impairment or behavioral disorders, but the severity of epilepsy and co-morbidities are quite variable. Genetic...
The Violet Study is exploring whether ganaxolone can reduce seizures, increase seizure free days, and improve behavior in children with PCDH19-related epilepsy.
