ALA dehydratase deficiency

Overview

Overview

ALA dehydratase deficiency (also called ALAD porphyria) is a rare cause of hepatic porphyria.[1][2] It is an autosomal recessive disorder that results from inappropriately low levels of the enzyme ALA dehydratase (ALAD, also called porphobilinogen synthase), which is required for normal heme synthesis.[1]
