    OBJECTIVE: To investigate the allelic heterogeneity of the ATP7B gene in Chinese patients with Wilson's disease (WD). METHODS: Exons of the ATP7B gene from 141 WD patients' DNA were amplified with polymerase chain reaction (PCR) 887-890. Mutations were then screened by single strand conformation polymorphism (SSCP) analysis and further identified by sequencing. RESULTS: The molecular structure of exon 7 of the ATP7B gene from 141 WD patients was analyzed. The same band shift in electrophoretic pattern of 4 cerebral type patients was identified with SSCP and subsequently sequenced. The results showed missense mutation at the second base of the codon as Ser 662 Cys, which is caused by a C to G transversion. CONCLUSIONS: Mutations of the ATP7B gene were investigated for the first time in China and a novel missense mutation was identified in four cases.
