In this study, we report further results of mutation analysis of the ATP7B gene in Wilson disease (WD) patients of Mediterranean origin. A total of 136 WD chromosomes, 73 of which were of Italian, 43 of Turkish, 18 of Sardinian, and two of Spanish origin, were analysed and the mutation characterised in 84.5% of them. We found 50 different mutations of which(More)
This study presents the update results of an ongoing project on the delineation of the spectrum of mutations at the Wilson disease (WD) gene in WD patients of Mediterranean origin. In studying 59 patients, of whom were 26 Continental Italians, 22 Sardinians, 9 Turkish, and 2 Albanians, we have found 31 novel and three known mutations. Of the novel(More)
We analyzed mutations and defined the chromosomal haplotype in 127 patients and Mediterranean descent who were affected by Wilson disease (WD), 39 Sardinians, 49 Italians, 33 Turks, and 6 Albanians. Haplotypes were derived by use of the microsatellite markers D13S301, D13S296, D13S297, and D13S298, which are linked to the WD locus. There were five common(More)
Wilson disease (WD) in the Sardinian population has an approximate incidence of 1:7,000 live births. Mutation analysis of the WD gene in this population reported in our previous articles led us to the characterization of two common mutations and a group of 13 rare mutations accounting for the molecular defect of 8.5, 7.9, and 15.1% of the WD chromosomes.(More)
In this study, we report the results of haplotype and mutation analysis of the ATP7B gene in Wilson disease (WD) patients of Greek origin. We have analysed 25 WD families and two single patients and characterised 94% of the WD chromosomes investigated. We have found 12 different molecular defects (three frameshifts, two splice site, two nonsense, five(More)
Wilson disease (WD) is an autosomal recessive disorder of copper metabolism resulting from the absence or dysfunction of a copper transporting P-type ATPase (ATP7B). Approximately 150 mutations of the ATP7B have been identified to date. In this paper, we report the results of molecular characterization and genotype-phenotype analysis, which we have carried(More)
In this study, we report the further results of an ongoing project on the delineation of the spectrum of mutations on the ATP7B gene in Wilson disease (WD) patients of Greek origin. We have analyzed 24 additional families and detected 16 mutations (five frameshifts, two splice site, two nonsense, and seven missense), of which six are novel. On adding these(More)
We describe a patient with Wilson disease who presented at 11 years of age with neurological symptoms and subsequent rapid progression of neurological impairment but absent hepatic manifestations. Molecular analysis showed compound heterozygosity for two frameshift mutations, 2299insC and 214delAT, which most likely result in an absent or inactive protein(More)
plasma cell-free DNA. To investigate whether organ transplantation was associated with a quantitative aberration in the concentrations of circulating DNA, we compared total plasma DNA concentrations in the transplant patients and the 10 healthy controls. The median DNA concentrations of the controls and the patients studied were 916.4 and 1336.3(More)
We have studied a patient with Wilson disease (WD), belonging to a family segregating late-onset, dominant cerebellar ataxia. Analysis of the WD gene showed that the patient is a compound heterozygote, carrying the 14His1069Gln mutation from the father and the 8Gly710Ser mutation from the mother. The 8Gly710Ser is a mutation described previously only in a(More)
