OFD1(Oral-Facial-Digital Syndrome 1)基因位于X染色体短臂(Xp22.2),编码一种中心体和基体相关蛋白,主要参与纤毛的形成和功能调控。该基因的突变会导致一种罕见的X连锁显性遗传病——口-面-指综合征1型(OFD1综合征),主要表现为口腔、面部及指/趾的发育异常,并可能伴随多囊肾、神经系统缺陷等。OFD1蛋白在细胞分裂、纤毛组装及信号转导中起关键作用,尤其在胚胎发育期间对组织形态发生至关重要。突变通常导致蛋白功能丧失,影响纤毛的正常形成,进而干扰Hedgehog等发育相关信号通路,引发多器官发育障碍。该基因属于中心体/基体相关基因家族,这类基因的共同特点是参与微管组织、细胞周期调控及纤毛相关功能。OFD1过表达可能破坏中心体复制平衡,导致染色体不稳定或纤毛异常增生;而表达降低则会引起纤毛缺陷,影响细胞运动、信号感知等功能,与肾囊肿、视网膜变性等疾病相关。此外,OFD1与初级纤毛疾病(纤毛病)密切相关,这类疾病常表现为神经、骨骼、视网膜等多系统异常。在女性携带者中,由于X染色体随机失活,症状严重程度存在差异,而男性半合子突变通常致死。研究还发现OFD1与细胞自噬、mTOR通路存在交互作用,可能影响代谢调控。该基因家族成员多具有保守的中心体定位序列,并在纤毛发生、细胞极性建立等过程中协同作用。
This gene is located on the X chromosome and encodes a centrosomal protein. A knockout mouse model has been used to study the effect of mutations in this gene. The mouse gene is also located on the X chromosome, however, unlike the human gene it is not subject to X inactivation. Mutations in this gene are associated with oral-facial-digital syndrome type I and Simpson-Golabi-Behmel syndrome type 2. Many pseudogenes have been identified; a single pseudogene is found on chromosome 5 while as many as fifteen have been found on the Y chromosome. Alternatively spliced transcripts have been described for this gene but the biological validity of these transcripts has not been determined. [provided by RefSeq, Jul 2008]
此基因位于X染色体上并且编码中心体蛋白。敲除小鼠模型已被用于研究突变在该基因的作用。小鼠基因也位于X染色体上,但是,与人类基因是不受X染色体失活。在这个基因的突变与口腔颌面数字综合征I型和Simpson-Golabi-Behmel辨证分型2.许多假已经确定有关;一个假的5号染色体上发现的,而多达15已在Y染色体上找到。可变剪接转录物已经被描述为这种基因,但这些转录物的生物有效性尚未确定。 [由RefSeq的,2008年7月提供]
