Mutation analysis was performed on 42 unrelated Israeli Arab CF patients. The previously known mutations in this population, β βF508, N1303K, G542X, 4010delTATT, and S549R(T>G), were identified in 57 CF alleles, leaving 28 CF alleles with unknown mutations.

β¦ Synopsis
Communicated by Lap-Chee Tsui
Upstate New York patients (100) with cystic fibrosis (i.e., 200 CF chromosomes), 72 from the CF center in Syracuse and 28 from a Buffalo CF center, were analyzed for their CF-causing mutations using restriction enzyme digest, single-strand conformation analysis (SSCA), and Heteroduplex (HA) analysis. Polymerase chain reaction (PCR) amplified products from all 27 CFTR exons using primers that included flanking intron junction sequence were investigated. More than 120 known cystic fibrosis transmembrane conductance regulator (CFTR) disease-causing mutations were screened. Four novel CFTR disease-causing mutations were identified (N287Y in exon 6b, 1259insA in exon 8, R1070P in exon 17b, and CF?20kbdel14b-18). A detection rate of 96% of the combined Syracuse and Buffalo population CF chromosomes was obtained.

We carried out molecular analysis of 80 chromosomes from 40 unrelated Mexican patients with a diagnosis of cystic fibrosis. The study was performed in two PCR steps: a preliminary one to identify mutation β¬F508, the most frequent cause of cystic fibrosis worldwide, and the second a reverse dot-blot
We have designed a study aimed at identifying the genetic mutations responsible for cystic fibrosis (CF) in the population of the United Arab Emirates. The prevalence of CF in the UAE is at least 1/15,000 live births and the disease is associated with very severe clinical presentations. We have inv
Asthma is a complex genetic disorder that affects 5% of adults and 10% of children worldwide. The complete characterization of the cystic fibrosis transmembrane conductance regulator (CFTR) gene identified missense mutations in 15% of 144 unrelated adult patients with asthma, but in none of 41 subje
A total of 540 individuals with clinical signs suggestive of cystic fibrosis (CF) was studied. The sweat chloride was measured and the DF508, G542X, R553X, and W1282X mutations of the CF gene were screened by polymerase chain reaction (PCR). With this approach the diagnosis of CF was confirmed in 12
We describe a general approach to derive fetal risk following two separate test results that each raise the likelihood of the same fetal abnormality without clearly determining whether the abnormality exists. Echogenic bowel observed on fetal ultrasonography may have multiple causes, including an a
