Osteoarticular pains and changes in Wilson's disease: a radiological study in fourteen patients in nine Turkish families.

A series of 14 patients with Wilson's disease were evaluated in order to determine the characteristic bone changes found in this metabolic disorder. The following radiologic and clinical findings deserve to be summarized: (1) Osteoarticular pains as first manifestations of Wilson's disease were found in six patients. (2) In all but 2 of our patients, minor or moderate or even severe bone abnormalities characteristic for Wilson's disease were observed. (3) There were three groups of sibs. Among these sibs, the lesions were not only similar in type but were also acquired approximately at the same time, showing the influence of the different genes responsible for this metabolic disorder.

Hemoglobin Istanbul: substitution of glutamine for histidine in a proximal histidine (F8(92) ).

A presumably spontaneous mutation has resulted in the formation of Hemoglobin (Hb) Istanbul in which glutamine is substituted for histidine in the proximal position of the beta-chain (F8(92)). The anemia and other physiological effects that occur in the presence of Hb Istanbul were much ameliorated by splenectomy. Hb Istanbul is a relatively unstable molecule which produces a rather moderate case of "unstable hemoglobin hemolytic anemia."In the determination of structure, a method of preferential cleavage of an aspartyl-proline bond at residues 99-100 of the beta-chain was used.
