| MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the hydroxymethylbilane synthase superfamily. The encoded protein is the third enzyme of the heme biosynthetic pathway and catalyzes the head to tail condensation of four porphobilinogen molecules into the linear hydroxymethylbilane. Mutations in this gene are associated with the autosomal dominant disease acute intermittent porphyria. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice heterozygous for one null allele and a functional allele with a milder mutation exhibit typical features of acute intermittent porphyria with massive urinary excretion of aminolevulinic acid after phenobarbital treatment, erythruria, ataxia, motor dysfunction, and neurologic muscle atrophy. [provided by MGI curators]
