The histopathological alterations seen in the liver biopsy of patients with A1AT deficiency may be the same as those observed in idiopathic neonatal hepatitis or in cases of extrahepatic biliary atresia During the period from February, to August,a great number of patients were referred to the Pediatric Gastroenterological Service, State University of Campinas, Campinas, SP, Brazil, in order to investigate hepatic diseases.

A clinical and laboratory cross sectional study of 70 patients at the Universidade Estadual de Campinas teaching hospital.

In this study, three akfa diagnosed with an A1AT deficiency had neonatal cholestasis and in two of these, before a definite diagnosis of the deficiency was established, the cholestasis was considered idiopathic. Molecular analysis provides a more precise diagnosis and may also be useful for the genetic counseling of patients with hepatic disease of unknown etiology. Orthotopic liver transplantation in children: Annu Rev Biochem ; The objective of this study was to identify S and Z allele carriers in patients suspected of having this deficiency and who showed laboratory and clinical characteristics of this disease.

The severity of cystic fibrosis was evaluated by Shwachman score. This protein has numerous variants, some of which are clinically relevant because their anomalous conformation alf that they fail to reach the target organs as they are polymerized in the hepatocyte.

Harris H, Hirchorn, Antitrripsina, editors. The main function of A1AT is to inhibit the action of neutrophilic elastase, a serine protease that hydrolyzes elastin fibers in the lungs Objective – The purpose of this study was to use DNA analysis to examine the presence of an alphaantitrypsin deficiency in 12 children suspected of having this deficiency and who showed laboratory and clinical characteristics of the disease.


The serum levels in Antitripina genotypes, which could theorically result in liver diseases, are usually normal. Among these investigations, the liver biopsy is of major importance.

The S allele results from the substitution of adenine by thiamin in exon III of the gene, which leads to glutamic acid at position being exchanged for valine and the consequent formation of an unstable protein structure 10, 11, Cystic fibrosis; alpha 1 antitrypsin. J Med Genet, 42pp.
