皮肤迟发性卟啉病(PCT)和肝红细胞生成性卟啉病(HEP)是由尿卟啉原脱羧酶(UROD)部分缺乏引起的。大约20%的PCT患者所有组织中的UROD浓度下降了50%,这是一种遗传的常染色体显性低外显性特征(II型PCT)。这种情况及其假定的纯合子对应的HEP都显示出遗传异质性。对一种红细胞UROD活性和浓度正常的家族性PCT(如I型或散发性PCT)的鉴定表明,常染色体基因可能在决定I型PCT的发病中起重要作用。临床上,PCT是肝脏特异性过程的结果,该过程导致UROD可逆性失活,并且可能是铁依赖的。控制细胞内活性UROD浓度的基因和促进失活过程的基因之间的相互作用可能决定了常见的肝毒性药物和其他获得性因素导致PCT的易感性。
Two types of human porphyria, porphyria cutanea tarda (PCT) and hepatoerythropoietic porphyria (HEP), result from partial deficiency of uroporphyrinogen decarboxylase (UROD). About 20% of patients with PCT have a 50% decrease in UROD concentration in all tissues that is inherited as an autosomal dominant trait with low penetrance (type II PCT). Both this condition and its postulated homozygous counterpart, HEP, show genetic heterogeneity. Identification of a form of familial PCT in which the activity and concentration of erythrocyte UROD is normal, as in type I or sporadic PCT, suggests that an autosomal gene, not necessarily at the UROD locus, may be important in determining the onset of type I PCT. Clinically overt PCT results from a liver-specific process that causes reversible inactivation of UROD and which may be iron dependent. The predisposition to develop PCT in response to common hepatotoxic agents and other acquired factors may be determined by interaction between genes that control the concentration of active UROD in cells and genes that facilitate the inactivation process.
