CONTEXT A downward trend in cystic fibrosis (CF) birth incidence has been reported in some areas. OBJECTIVE To evaluate the association between carrier screening and CF birth incidence. DESIGN, SETTING, AND PARTICIPANTS In northeastern Italy, CF birth incidence is monitored by means of a long-standing neonatal screening program. In the same area, 2(More)
Human infertility in relation to mutations affecting the cystic fibrosis transmembrane regulator (CFTR) gene has been investigated by different authors. The role of additional variants, such as the possible forms of the thymidine allele (5T, 7T and 9T) of the acceptor splice site of intron 8, has in some instances been considered. However, a large-scale(More)
Maroteaux-Lamy syndrome is an autosomal-recessive disorder due to the deficit of the lysosomal enzyme, arylsulfatase B (ARSB). Among the numerous genomic lesions reported till now, the sequence variant, c.1151G>A (p.S384N), has been associated with a severe phenotype in more than 10% of the patients. We now report the first in vivo demonstration of the(More)
We have developed a simple rapid DNA screening test that allows us simultaneously to analyze seven CF mutations (deltaF508, R347P, S549N, G551D, R553X, R334W, 444delA) that together account for about 60% of all CF mutations in the Italian population. It consists of three steps: multiplex polymerase chain reaction (PCR) amplification of exons 4, 7, 10 and(More)
Following cystic fibrosis (CF) neonatal screening implementation, a high frequency of heterozygotes has been reported among neonates with elevated immunoreactive trypsinogen (IRT) and normal sweat chloride levels. We studied the relationship between normal IRT values and CF heterozygosity: 10,000 neonates were screened for CF by IRT measurement and tested(More)
PURPOSE We evaluated the effects of cystic fibrosis (CF) carrier screening on birth prevalence trends and newborn screening (NBS) efficiency by comparing two Italian regions; carrier screening was performed in one region (eastern region (ER)) and not in the other (western region (WR)). METHODS Annual births of infants with CF, NBS false-positive results,(More)
To explore the utility of the bacteriophage T7 binary system in adenovirus (Ad) vectors we constructed three Ad5-based vectors containing the T7 RNA polymerase (T7pol) gene in either early region 1 (E1) or E3. The recombinant Ad vectors were either deficient (AdT7pol1, AdT7pol2) or competent (AdT7pol3) for replication in human cells other than Ad5(More)
Hunter syndrome is a lethal lysosomal storage disorder caused by the deficiency of iduronate-2-sulfatase and characterized by severe skeletal and neurological symptoms. Only symptomatic treatments are available and, although bone marrow transplantation has been suggested, no encouraging results have been obtained so far. Therefore, gene therapy might be a(More)
BACKGROUND Cystic Fibrosis (CF) is one of the most common autosomal recessive genetic disorders, with the majority of patients born to couples unaware of their carrier status. Carrier screenings might help reducing the incidence of CF. METHODS We used a semi-automated reverse-dot blot assay identifying the 47 most common CFTR gene mutations followed by(More)
