A 6-year-old male patient presented with Budd-Chiari syndrome and glycoprotein abnormalities associated with carbohydrate deficient glycoprotein syndrome type I with yet unidentified molecular defect (type Ix). Budd-Chiari syndrome most likely developed after hepatic venous thrombosis caused by coagulation abnormalities resulting from hypoglycosylation and functional impairment of anticoagulant proteins.
