基因 CPT2 与疾病

CPT2基因编码肉碱棕榈酰转移酶2,在脂肪酸代谢中具有重要作用,该酶转运肉毒碱以及辅酶A,长链脂肪酸与肉毒碱结合并与辅酶A连接后才能进入线粒体,随之代谢为能量,为相关组织器官供能。

已发现70多种突变,会导致肉碱棕榈酰转移酶2缺乏症,长链脂肪酸无法进入线粒体内进入代谢为能量,进而导致肌肉疼痛、肌无力、低血糖等,同时也会对肝脏、心脏和肌肉等造成损害。

CPT2 carnitine palmitoyltransferase 2 1p32 5 约3094 bp
基因摘要 The protein encoded by this gene is a nuclear protein which is transported to the mitochondrial inner membrane. Together with carnitine palmitoyltransferase I, the encoded protein oxidizes long-chain fatty acids in the mitochondria. Defects in this gene are associated with mitochondrial long-chain fatty-acid (LCFA) oxidation disorders. [provided by RefSeq, Jul 2008].
