The Multidrug Resistance protein (, ) is involved in the transport of xenobiotics and antiretroviral drugs. Some variants of the gene are of clinical importance; among them, exon 12 (c.1236C>T, rs1128503), 21 (c.

Article Synopsis
  • In Argentina, porphyria cutanea tarda (PCT) is linked with HIV infection, but the relationship with HIV and antiretroviral therapy remains unclear.
  • The study examines specific genetic variants that influence drug metabolism and their potential role in the onset of PCT among HIV-infected patients.
  • Findings show that certain gene variants are more frequent in PCT patients, suggesting that genetics, along with antiretroviral therapy, may contribute to the development of PCT in those with HIV.

Porphyrias are a group of metabolic diseases that arise from deficiencies in the heme biosynthetic pathway. A partial deficiency in hydroxymethylbilane synthase (HMBS) produces a hepatic disorder named Acute Intermittent Porphyria (AIP); the acute porphyria is more frequent in Argentina. In this paper we review the results obtained for 101 Argentinean AIP families and 6 AIP families from foreign neighbour countries studied at molecular level at Centro de Investigaciones sobre Porfirinas y Porfirias (CIPYP).

AIP is an acute liver disorder caused by a deficiency of porphobilinogen deaminase (PBGD) characterized by neuroabdominal symptoms. It is an autosomal dominant disease. However, homozygous dominant AIP (HD-AIP) have been described.

Hepatoerythropoietic Porphyria (HEP) is the rare homozygous form of Porphyria Cutanea Tarda (PCT). It is characterized clinically by the early onset of severe skin manifestations which can be confused with Congenital Erythropoietic Porphyria (CEP) or with PCT when the symptoms are mild. We describe the case of a 14 year-old child with skin manifestations similar to those observed in PCT.
