WebAcute intermittent porphyria (AlP) is an autosomal dominant inherited condition caused by mutations in the porphobilinogen deaminase (PBGD) gene. The PBGD gene is located on chromosome 11 q24.1 -24.2 and spread over fifteen exons. The protein encoded by this gene is a rate-limiting enzyme, the PBGD enzyme, in the haem synthetic pathway.
