Improvement in sensitivity of allele-specific PCR facilitates reliable noninvasive prenatal detection of cystic fibrosis.
BACKGROUND Cell-free fetal DNA circulating in maternal blood has potential as a safer alternative to invasive methods of prenatal testing for paternally inherited genetic alterations, such as cystic fibrosis (CF) mutations. METHODS We used allele-specific PCR to detect mutated CF D1152H DNA in the presence of an excess of the corresponding wild-type sequence. Pfx buffer (Invitrogen) containin...
متن کاملOptimized sensitivity of allele-specific PCR for prenatal typing of human platelet alloantigen single nucleotide polymorphisms.
PCR using sequence-specific primers (PCR-SSP) is widely employed for the genotyping of single nucleotide polymorphisms (SNPs) in both routine diagnosis and medical research. The human platelet alloantigens (HPAs) represent SNPs in platelet-specific glycoproteins, and HPA-1, -2, -3, and -5 are the most relevant in immunohematology. In most protocols, the respective HPA-SNPs are analyzed in allel...
متن کاملDetection of Ethambutol-Resistant Associated Mutations in Mycobacterium tuberculosis Isolates from Iran Using Multiplex Allele-Specific PCR
Tuberculosis is a serious global public health problem and its high prevalence is stron gly associated with the enhancement of drug resistance. In this study we demonstrate a multiplex allele-specific polymerase chain reaction (MAS)-PCR assay to simultaneously detect mutations in the first and third bases of the embB gene codon 306 ATG in ethambutol (EMB) resistant isolates of Mycobacterium t...
متن کاملthe role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Prevalence of Cystic Fibrosis Trans-membrane Conductance Regulator Gene common mutations in children with cystic fibrosis in Isfahan, Iran
Background: Cystic fibrosis (CF) is the most common lethal genetic disorder of Cystic Fibrosis Trans-membrane Conductance (CFTR) Regulator gene mutations. We aimed to investigate common mutations in CF patients and to assess its possible relationship with clinical presentations. Materials and Methods: This cross sectional study was conducted on 36 CF patients who were referred to a tertiary ped...
