Alpha 1 antitrypsin (AAT) deficiency is a hereditary disorder leading to severe lung and liver diseases worldwide. An accumulation of insoluble heterodimer AAT molecules in hepatocytes is the main cause of liver disorders. The most commonly detected allele worldwide is the PIMM allele, which fulfills the AAT function. The most common missing variant is PiZZ. Serum AAT level is a beneficial but not a reliable determinant for diagnosis. Liver biopsy yields more reliable results. AAT deficiency has no specific treatment. The only treatment modality in children with end stage liver disease is the hepatic transplant. We wanted to present in our article four cases from same family, diagnosed alpha-1 antitrypsindeficiency in adulthood.
