Abstract
This paper reports on a study of the heterozygous children of patients with Wilson's disease. A total of 16 children of 10 patients with the disease were followed up. Detailed biochemical, clinical and EEG tests were done. Nearly all the children were found to have reduced serum copper and caeruloplasmin levels and high rates of urine copper excretion following exposure to penicillamine. These findings were different from the results obtained in adult heterozygous carriers. Thirty per cent of the children had pathological neurological findings, and EEG abnormalities were found in 75%.
