Background: The variable numbers of tandem-repeat (VNTR) alleles at the phenylalanine hydroxylase (PAH) gene have been used in carrier detection and prenatal diagnosis in phenylketonuria families. This study was carried out to analyze VNTR alleles at the PAH gene in Iranian Azeri Turkish population. Methods: In this study, 200 alleles from general population were studied by PCR. Results: The fr...

The variable numbers of tandem repeats (VNTR) analysis is a method frequently employed as a molecular epidemiological tool for Mycobacterium tuberculosis genetic fingerprinting. In this study, we characterized the population of M. tuberculosis circulating in Mie Prefecture, Japan, and assessed the utility of the proposed JATA12- and 15-VNTR analyses of 158 M. tuberculosis clinical isolates ...

Usher syndrome type IC is a rare, autosomal recessive sensorineural disorder caused by mutations in the USH1C gene, which encodes a PDZ-domain protein named harmonin. The Acadian-specific 216G-->A mutation in exon 3 and a variant 9-repeat VNTR allele (designated VNTR(t,t)) in intron 5 are in complete linkage disequilibrium. (The usual form of the allele is referred to as VNTR(t).) To gain insig...

Strain comparison is important to population genetics and to evaluate relapses in patients with Mycobacterium avium complex (MAC) lung disease, but the "gold standard" of pulsed-field gel electrophoresis (PFGE) is time-consuming and complex. We used variable-number tandem repeats (VNTR) for fingerprinting of respiratory isolates of M. intracellulare from patients with underlying bronchiectasis,...

BACKGROUND Combining different molecular typing methods for Mycobacterium tuberculosis complex (MTBC) can be a powerful tool for molecular epidemiology-based investigation of TB. However, the current standard method that provides high discriminatory power for such a combination, mycobacterial interspersed repetitive units-variable numbers of tandem repeats typing (MIRU-VNTR), is laborious, time...
