DEFINING THE GENETIC DRIVERS OF ADULT-ONSET CHOLESTATIC LIVER DISEASE
Italy60 participantsStarted 2025-11-01
Plain-language summary
Cholestatic disease in adults comprises a heterogeneous group of conditions characterized by intra- or extrahepatic alterations of bile flow that can lead to fibrosis or hepatic decompensation. Due to the heterogeneity of clinical manifestation, which is sometimes very subtle, diagnosis based on clinical, histological, and radiological evaluation is often very complicated. Genetic testing can be helpful in identifying the cause of the clinical phenotype, thereby allowing for targeted follow-up adequate to the patient's specific characteristics and risk factors. Although the utility of genetic analysis has been well documented for other liver diseases or in pediatric cohorts of children with cholestatic disease, the use and benefits of genetic testing in adults with cholestatic disease are still little explored and investigated. In this context, through the use of whole-genome sequencing (WGS), the FIRST project aims to evaluate the role of rare genetic variants in the pathogenesis of cholestatic disease and the utility of WGS in defining a genetic diagnosis.

Inclusion criteria
✓. persistent or intermittent elevations in serum alkaline phosphatase (ALP) or gamma-glutamyltransferase (GGT) for at least six months not explained following standard diagnostic assessment adhering to the guidelines of the European Association for the Study of the Liver (EASL), or with a positive family history of unexplained cholestasis or hepato-biliary cancer, negative to previous genetic tests (targeted panel for PFIC genes or WES);
✓. primary sclerosing cholangitis (PSC) with unusual features: small-duct PSC, non-typical radiological findings according to radiological guidelines on PSC, absence of concomitant inflammatory bowel disease, negative to previous genetic tests (targeted panel for PFIC genes or WES) or who didn't perform previous genetic test;
✓. primary biliary cholangitis (PBC) without specific anti-mitochondrial antibodies, negative to previous genetic tests (targeted panel for PFIC genes or WES) or who didn't perform previous genetic test.
✓Blood donors (age 18-65 years) without clinical signs of liver diseases based on the collected clinical parameters: anthropometric (BMI\>18 and \<25), haematological (Hb, white blood cells, platelets within the reference range), biochemical traits (albumin, bilirubin, AST, ALT, GGT, ALP within the reference range), medical history (negative for chronic or concomitant diseases, including immunological diseases)
