Such liver bypass can cause several health problems, one of the most severe being portopulmonary hypertension (PoPH).\n\nThe goal of this study is to identify pathogenic and potentially pathogenic genetic variants in patients who have both CPSS and PoPH. Future research will assess the contribution of these genetic variants to the development of PoPH.\n\nThe long-term goal is to use genetic information to identify patients with congenital portosystemic shunts (CPSS) or chronic liver disease who are at risk of developing PoPH to offer anticipatory management.\n\nChildren and adult patients with both CPSS and PoPH, as well as their close relatives (patient's parents and siblings) can take part in the study. Genetic variations within each family will be studied.",[26,27,28],"Portopulmonary Hypertension","Pulmonary Arterial Hypertension (PAH)","Congenital Portosystemic Shunt",[30,31,32,33,34,35],"CPSS","PoPH","PAH","Genetic","Genomic","IRCPSS","NOT_YET_RECRUITING","2026-01-15",{"date":39,"type":40},"2026-01-20","ACTUAL",{"date":42,"type":22},"2026-02-01",{"date":44,"type":22},"2030-01-31",{"name":46,"class":47},"Prof. Valérie Mc Lin","OTHER"]
