Gender difference of serum ceruloplasmin was analyzed among healthy children, WD patients and heterozygotes. A There were no significant gender differences of serum ceruloplasmin levels intra each age subgroup among WD patients and among healthy children. B Serum ceruloplasmin level was higher in boys than girls among healthy children (p < 0.01) and also among WD patients (p < 0.05). The mean levels of serum ceruloplasmin in WD patients were much lower than that in healthy controls and heterozygotes
