摘要 RAS/ 丝裂原激活蛋白激酶(RAS/mitogenactivitedprotein kinase,RAS/MAPK)信号通路参与调控细胞增殖、分化、存活、凋亡、免疫应答等行为,编码RAS/MAPK 信号通路蛋白的基因发生突变,可引起RAS 信号通路相关综合征(RASopathies)[1],其发病率约为1/1 000。RAS 基因包含NRAS(neuroblastoma-RAS)、HRAS(harvery-RAS)、KRAS(kirsten-RAS)等,编码由上游调节子激活的小三磷酸鸟苷(guanosine triphosphate,GTP)酶单体,激活多种信号通路,传递胞外信号启动下游信号通路,包括RAS/MAPK 通路[2]。RAS/MAPK 信号通路失调会引起淋巴发育不良、先天性心脏病、肺动脉瓣狭窄、男性隐睾、青春期发育迟缓等,外观上的典型表现为低耳位、高睑缘、上睑下垂、宽颈、胸廓脊柱畸形等。另外RAS/MAPK 信号通路在介导胰岛素样生长因子1(insulin-like growth factor-1,IGF-1)的细胞内信号转导中也起着重要作用,IGF-1 介导生长激素的出生后生长效应 [3],身材矮小是各型RASopathies 患者的共同特征。
