This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose is to characterize enzyme defects in patients with known or suspected porphyria and their families. Methods include measurement of porphobilinogen deaminase and porphyrins in erythrocytes, porphyrins and porphyrin precursors (delta-aminolevulinic acid and porphobilinogen) in plasma and urine, and porphyrins in feces. Selected patients are entered in other porphyria research protocols at this and other institutions, including analysis of DNA to identify specific mutations in genes for heme biosynthetic pathway enzymes.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 目的是表征已知或疑似卟啉症患者及其家属的酶缺陷。方法 包括测量红细胞中胆色素原脱氨酶和卟啉、卟啉和卟啉前体 血浆和尿液中的（δ-氨基乙酰丙酸和胆色素原）以及粪便中的卟啉。 入选患者包括 参与了该机构和其他机构的其他卟啉症研究方案，包括分析DNA以识别 血红素生物合成途径酶基因的特定突变。
