Wilson's disease (WD) is an autosomal recessive disorder caused by a defective function of the copper transporting ATP7B protein. Analysis of ATP7B gene in the Sardinian population revealed the presence of six common mutations that together account for 85% of WD chromosomes. We have developed an automated approach for the detection of these 6 common Sardinian mutations based on TaqMan technology. Ten DNA samples of WD patients carrying different combinations of the six most common Sardinian mutations and normal controls previously analysed were used in triplicate to set up the allelic discrimination assays. The system was validated in 96 samples obtained from WD patients carrying different combinations of the most common mutations under investigation. The results showed that allelic discrimination is a valid method that could be used for efficient diagnosis of single cases but also for a mass screening.
