Galactose-1-phosphate uridyl transferase (GALT) catalyzes the second step of the Leloir pathway of galactose metabolism, namely the conversion of UDP-glucose + galactose-1-phosphate to glucose-1-phosphate + UDP-galactose. The absence of this enzyme results in classic galactosemia in humans and can be fatal in the newborn period if lactose is not removed from the diet. The pathophysiology of galactosemia has not been clearly defined. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
[中文简述(自动翻译):]  半乳糖-1-磷酸尿苷酰转移酶(GALT)催化半乳糖代谢,UDP-葡萄糖+半乳糖-1-磷酸的即转化为葡萄糖-1-磷酸+ UDP-半乳糖的leloir途径的第二个步骤。缺乏这种酶会导致经典半乳糖血症在人类和如果乳糖不从饮食中删除可以在新生儿期死亡。半乳糖血症的病理生理机制还没有明确的规定。已发现该基因编码不同亚型的两个转录变异体。 [由RefSeq的,2012年4月提供]
