| Abstract: | This study reports 12 novel mutations of the Wilson disease (WD) gene which have been detected by the molecular analysis
of 29 patients of Mediterranean descent carrying uncommon chromosomal haplotypes at the WD locus. These mutations include
two nonsense, one splice site and nine missense. The missense mutations lie in regions of the WD gene critical for its function,
such as the transmembrane region, the transduction domain and the ATP loop and ATP-binding domain, indicating that they are
disease-causing mutations. These new findings improve our knowledge for the role played by functional domains on the ATP7B
function.
