High Prevalence of α‐1‐Antitrypsin Heterozygosity in Children With Chronic Liver Disease

Abstract excerpt

OBJECTIVE: Alpha-1-antitrypsin (A1AT) deficiency is the most common genetic cause of liver disease in children; however, the role of polymorphic heterogeneity in the A1AT gene as a modifier of other forms of pediatric liver disease is not clear. We hypothesized that non-M A1AT allele variants are more common in children with chronic liver disease than in the general population. METHODS: A retrospective,...
