title: 'Durate variant with clinical signs' has alpha1 -antitrypsin genotype ZZ.
abstract: A patient with neonatal jaundice and cirrhosis who was previously reported homozygous for the Durate variant of galactose-1-phosphate uridyl transferase has the ZZ genotype for alpha1-antitrypsin. A sister of the patient, also with ZZ genotype, is less severly affected with liver disease and is a heterozygote for the Durate variant. Since a number of patients with ZZ genotype of alpha1-antitrypsin have been previously reported to have liver disease, the latter genotype is the more probable explanation for the patients' clinical state. A question is raised, however, whether the Duarte variant may be specifically associated with the development of liver disease in ZZ individuals.
