Introduction Blau syndrome (BS) is a rare autosomal dominant, autoinflammatory syndrome characterized by the clinical triad of granulomatous, recurrent uveitis, dermatitis and symmetric arthritis. The arthritis is usually a polyarticular exuberant synovitis and tenosynovitis and represents the characteristic phenotypic feature. Uveitis occurs in most patients and commonly evolves to a panuveiti...

We have performed molecular genetic analyses on 160 Brazilian patients diagnosed with cystic fibrosis (CF). Screening of mutations in 320 CF chromosomes was performed through single strand conformation polymorphism (SSCP) and heteroduplex analyses assay followed by DNA sequencing of the 27 exons and exon/intron boundaries of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. T...

Familial Blau syndrome and sporadic early-onset sarcoidosis (EOS) are both systemic granulomatous diseases evoked by the spontaneous activation of mutated NOD2. In Japan, the R334W amino acid substitution is more frequently identified, whereas the R334Q mutation is rare and, in contrast to western countries where disease causing mutations are typically hereditary, most Japanese cases derive fro...

The analysis of 2 diallelic loci (M470V and T854T) and a microsatellite IVS8(T)n of the cystic fibrosis transmembrane conductance regulator (CFTR) gene has shown different haplotype distribution in Brazilian cystic fibrosis (CF) chromosomes carrying different CF mutations. The DeltaF508 mutation was in absolute linkage disequilibrium with 1-1 haplotype (M470V-T854T). Most of DeltaF508 chromosom...

Uveitis is a clinical feature of the Blau syndrome, a disease linked to CARD15 (also referred to as NOD2) mutations. Three main mutations in this gene (R334W, R334Q and L469F) have been reported as Blau syndrome risk factors, a disease that manifests uveitis as one of its clinical features. However, little is known on the involvement of this gene in idiopathic uveitis. We thus sought to determi...

Results 8 patients were diagnosed. The onset age was from 1 month to 5 years. Three of them were misdiagnosed as JIA and Takayasu's arteritis respectively. One case had family history. All patients has had typical rash, joints problem, bilateral pan-uveitis. Two had hearing lose, four had Takayasu's arteritis with hypertension, and two of them had renal artery stenosis with severe hypertension ...

OBJECTIVE Cystic fibrosis (CF) is a common autosomal recessive genetic disease caused by a mutation in the CF transmembrane conductance regulatory (CFTR) gene. This study attempted to identify the most common CFTR mutations and any correlations between certain mutations and the clinical presentation of the disease in CF patients in southwestern Iran. METHODS Twenty nine common CFTR gene mutat...

Cystic fi brosis is an autosomal recessive disease. Its incidence in Cuba is 1 in 5000 live births. The molecular cause underlying this disease is related to mutations in the regulatory gene encoding the cystic fi brosis transmembrane regulator (CFTR). In this study, the techniques for the study of IVS17bTA microsatellite marker were standardized, and the most frequent mutations in the CFTR gen...

Introduction: There have been significant advancements in the treatment of cystic fibrosis (CF), particularly for people who are eligible CFTR modulators drugs. However, there is an unequal access to these drugs worldwide. Currently, Brazil, only Ivacaftor approved public health system. The state Bahia, located Northeast presents a highly admixture population. In spite this F508del variant most...
