Wilson disease (WD) is an autosomal recessive disorder resulting in pathological progressive copper accumulation in liver and other tissues. The worldwide prevalence (P) is about 30/million, while in Sardinia it is in the order of 1/10,000. However, all of these estimates are likely to suffer from an underdiagnosis bias. Indeed, a recent molecular neonatal(More)
Herein we report the results of mutation analysis of the ATP7B gene in a group of 134 Wilson disease (WD) families (268 chromosomes) prevalently of Italian origin. Using the SSCP and sequencing methods we identified 71 disease-causing mutations. Twenty-four were novel, while 19 more mutations already described, were identified in new populations in this(More)
Wilson's disease (WD), an autosomal recessive disorder of copper transport with a broad range of genotypic and phenotypic characteristics, results from mutations in the ATP7B gene. Herein we report the results of mutation analysis of the ATP7B gene in a group of 118 Wilson disease families (236 chromosomes) prevalently of Italian origin. Using DNA(More)
OBJECTIVES Herein we report the results of mutation-based screening for Wilson disease (WD) in 2 isolated populations of Sardinia and the Greek island of Kalymnos. PATIENTS AND METHODS Mutation analysis was performed in 110 and 9 WD families originating respectively from Sardinia and Kalymons using single-strand conformation polymorphism and sequencing(More)
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(More)
Wilson disease is an autosomal recessive disorder caused by defective function of the copper transporting protein ATP7B. Approximately 520 Wilson disease-causing mutations have been described to date. In this study we report the use of DNA and RNA analysis for molecular characterization of a gross deletion of the ATP7B gene detected in homozygosity in a(More)
Approximately 520 Wilson disease-causing mutations in the ATP7B gene have been described to date. In this study we report DNA and RNA analyses carried out for molecular characterization of a consensus sequence splicing mutation found in homozygosity in a Swiss Wilson disease patient. RNA analysis of 1946 +6 T→C in both the peripheral lymphoblasts and liver(More)
Diagnosis of Wilson's disease (WD) still remains a challenge since no single test has an accuracy of 100%. Molecular testing for ATP7B gene mutations can help reach the diagnosis when routine testing is equivocal. We herein report an asymptomatic WD patient diagnosed accidentally by genetic analysis. Th is case suggests that WD is a challenge even in(More)
BACKGROUND Wilson's disease diagnosis is still a challenge for clinicians. AIM To underline the importance of genetic testing in carrier detection and diagnosis of atypical Wilson's disease cases. METHODS Two families with Wilson's disease in two consecutive generations were analysed with clinical, biochemical and genetic testing. RESULTS In one(More)
Wilson disease (WD) is an autosomal recessive disorder caused by a defective function of the copper-transporting ATP7B protein. This results in progressive copper overload and consequent liver, brain, and kidney damage. Approximately 300 WD-causing mutations have been described to date. Missense mutations are largely prevalent, while splice-site mutations(More)
