WDFY3基因介绍 was created by 凤凰

基因产物:自噬相关FYVE蛋白。

蛋白功能:可通过和P62蛋白相互作用通过自噬途径对错误折叠的泛素化蛋白进行降解,此外可能以自噬依赖的方式通过对DVL3 聚集体的清除来调节Wnt 信号通路[1-2]。

相关疾病:常染⾊体显性原发性小头畸形?(AD)(可有轻到中度的神经发育障碍、智力缺陷、大小头畸形(有认为单倍体不足可能和大头畸形有关,而该蛋白PH结构域上的变异和小头畸形有关)以及出现自闭症谱系障碍、注意力缺陷多动障碍等异常[2-3],此外HPO数据库记录该基因和癫痫发作这一表型有关联(但笔者目前未找到相关病例报道))。

相关临床及基础研究:PubMed数据库(PMID:  34187232 (J Cereb Blood Flow Metab. 2021) 31327001 (Brain. 2019) )。
