| ferrochelatase |
Brenner et al (Am J Hum Genet 50:1203-1210 1992) reported that this fibroblast culture from a patient with protoporphyria had deficient ferrochelatase activity. Ferrochelatase mRNA levels measured by northern blotting were found to be equal to those found in normal controls. EC Number: 4.99.1.1 |
| |
| Remarks |
Photosensitivity since infancy; deficient heme synthetase activity; normal delta-aminolevulinic acid synthetase activity; 2 affected children; fibro show normal ferrochelatase mRNA levels & def enzyme activity |
