基因产物：溶质载体家族2(促进葡萄糖转运体)成员1。

蛋白功能：是血脑屏障中的主要葡萄糖转运蛋白，有利于葡萄糖向大脑的转运[1]。

相关疾病：肌张力障碍（AD）[2]；重度GLUT1缺乏综合症1型（婴儿期发病）（AD,AR）[3]；GLUT1缺乏综合症2型（儿童期发病）（AD）[4]；红细胞膜整合蛋白缺乏冷水肿细胞增多症伴神经功能缺陷（AD）[5]；特发性全面性癫痫（易感基因）（AD）[6]； 癫痫伴肌阵挛失张力发作（Doose syndrome） [7]； 儿童失神癫痫 [8]。

相关临床研究：PubMed数据库（PMID: 20129935 (Brain. 2010) ; PMID: 18577546 (Brain. 2008) ）

用药提醒：该基因突变所致的癫痫使用生酮饮食往往会取得很好的效果。
