Résumé

Autosomal dominant polycystic liver disease (ADPLD) is a rare condition with a female preponderance, mainly based on pathogenic variants in two genes, PRKCSH and SEC63. Clinically, ADPLD is characterized by vast heterogeneity, ranging from asymptomatic to highly symptomatic hepatomegaly. To date, little is known about the prediction of disease progression at early stages, hindering clinical management, genetic counseling, and the design of randomized controlled trials. To improve disease prognostication, we built a consortium of European and American centers to recruit the largest cohort of patients with PRKCSH and SEC63 liver disease. We analyzed an international multicenter cohort of 265 patients with ADPLD harboring pathogenic variants in PRKCSH or SEC63 for genotype-phenotype correlations, including normalized age-adjusted total liver volumes (nTLV) and PLD-related hospitalization (liver event) as primary clinical endpoints. Classifying individual nTLV into predefined progression groups yielded predictive risk discrimination for future liver events independent of sex and underlying genetic defects. Additionally, disease severity, defined by age at first liver event, was significantly more pronounced in females and patients with PRKCSH variants than in those with SEC63 variants. A newly developed sex-gene score was effective in distinguishing mild, moderate, and severe disease in addition to imaging-based prognostication. Both imaging and clinical genetic scoring have the potential to inform patients about the risk of developing symptomatic disease throughout their lives. The combination of female sex, germline PRKCSH alteration, and rapid TLV-progression is associated with the greatest odds of PLD-related hospitalization.

BACKGROUND & AIMS OBJECTIVE
Autosomal dominant polycystic liver disease (ADPLD) is a rare condition with a female preponderance, mainly based on pathogenic variants in two genes, PRKCSH and SEC63. Clinically, ADPLD is characterized by vast heterogeneity, ranging from asymptomatic to highly symptomatic hepatomegaly. To date, little is known about the prediction of disease progression at early stages, hindering clinical management, genetic counseling, and the design of randomized controlled trials. To improve disease prognostication, we built a consortium of European and American centers to recruit the largest cohort of patients with PRKCSH and SEC63 liver disease.
METHODS METHODS
We analyzed an international multicenter cohort of 265 patients with ADPLD harboring pathogenic variants in PRKCSH or SEC63 for genotype-phenotype correlations, including normalized age-adjusted total liver volumes (nTLV) and PLD-related hospitalization (liver event) as primary clinical endpoints.
RESULTS RESULTS
Classifying individual nTLV into predefined progression groups yielded predictive risk discrimination for future liver events independent of sex and underlying genetic defects. Additionally, disease severity, defined by age at first liver event, was significantly more pronounced in females and patients with PRKCSH variants than in those with SEC63 variants. A newly developed sex-gene score was effective in distinguishing mild, moderate, and severe disease in addition to imaging-based prognostication.
CONCLUSIONS CONCLUSIONS
Both imaging and clinical genetic scoring have the potential to inform patients about the risk of developing symptomatic disease throughout their lives. The combination of female sex, germline PRKCSH alteration, and rapid TLV-progression is associated with the greatest odds of PLD-related hospitalization.
