It is characterized by anorexia, weight loss and an enlarged abdomen. HB is more common in patients with familial adenomatous polyposis (FAP), and can occur in patients with other pre-existing liver conditions. About 5% of HB cases are associated with genetic factors, especially overgrowth syndromes, such as Beckwith-Wiedemann syndrome (BWS) or hemihypertrophy. MEDGEN:61644 MONDO:0018666
