Eight months of performing serum proteomics to identify biomarkers that reflect liver disease severity and predict poor outcomes
Multi-omic spatial analysis of human AATD-LD.
Eight months of conduction of spatial multi-omic analyses comparing pediatric and adult liver tissues. This will include proteomic and transcriptomic mapping to understand how AAT accumulation and ductular reactions differ between the two forms.

* Adult patients (≥18 years) with genetically confirmed alpha-1 antitrypsin deficiency (Pi\*ZZ genotype). * Availability of longitudinal clinical follow-up data (minimum 5 years) within the AATD consortium. * At least one documented liver assessment including liver stiffness measurement (LSM) and serum-based fibrosis markers. * Availability of stored serum samples for proteomic analysis. * For translational analyses: availability of liver tissue samples (pediatric or adult) and/or induced pluripotent stem cell (iPSC)-derived hepatocyte-like cells.
