Fahr病是特发性基底节钙化(Idiopathic basal ganglia calcification,IBGC)的俗称,是一种以基底节及大脑其他部位钙化为特征的神经系统遗传疾病,患者可出现运动障碍及认知、精神异常,尚无有效药物治疗.本研究通过家系连锁分析和候选基因克隆,发现导致该疾病发生的第一个致病基因SLC20A2,目前发现有40%的IBGC患者因携带SLC20A2突变致病,提示该基因为IBGC最常见的致病基因.SLC202基因突变是如何导致IBGC发生、发展呢?SLC20A2变所影响的下游靶基因及其调控功能?本研究运用酵母双杂交研究SLC20A2编码的蛋白PiT2相互作用蛋白及其对PiT2蛋白的调控作用;构建果蝇和小鼠SLC20A2基因敲除和转基因模型,体内研究SLC20A2突变导致IBGC发生发展过程及与其互作蛋白机制,揭示IBGC发生的分子机理;同时在IBGC小鼠模型中研究了中药方剂SYM和西药羟乙二磷酸二钠对小鼠颅内钙化的影响.
