Although the age of onset, severity, type of symptoms, and rate of progression of AATD cannot be predicted in sibs based on genotype some estimates are available on the risk to sibs of developing severe liver disease in infancy [ Cox ].

Pathogenic alleles that result in either no mRNA product or no protein production. An attempt to correlate serum AAT levels with protein variants in children showed trends similar to those seen in adults [ Donato et al ]. All individuals with severe AATD: The most common manifestation of AATD-associated liver disease is jaundice, with hyperbilirubinemia and raised serum aminotransferase levels in the early days and months of life.
