step 1 Mnemonic for the Hereditary porphyrias..this is how i am used to remembering them:
All---------------Acute Intermittent Porphyria
Congenital------Congenital erythropoetic Porphyria
Porphyrias------Porphyria Cutanea Tarda
Have------------Hereditary Coprophyria
Variable---------Variegate Porphyria
Presentation----Protoporhyria
Now all u got to do is memorize the pathway......
the first enzyme.....ALA synthase and ALA dehydrase have no deficincies that i know of and even if they did then they wldn't cause porphyria.....
then you got the next enzyme
Uroprophyrinogen I synthase..............Acute I.Porphyra
Uroporphyrinogen III co-synthase.......Congenital erythropoetic Porphyria
Uroporphyrinogen III decarboxylase....Porphyria Cutanea Tarda
Coprophyrinogen III oxidase...............Hereditary Coprophyria
Protoporhyrinogen oxidase.................Variegate Porphyria
Ferrochelatase....................................Protoporhyria
this ends heme synthesis.....
I just placed the diseases in the order of the enzymes so that it wldn't be tough to recall the enzyme with the specific disease....but u have to memorize the pathway in order for u to be able to do that....
Not sure if it is high yield.....I guess if u rememebr Acute Inet. Porphyria and PCT ...these two are the important ones....
along with maybe lead poisoning......
