Identification of NF-[kappa]B1 and NF-[kappa]BI[Alpha] Polymorphisms Using PCR-RFLP Assay in a Turkish Population

A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was used in a Turkish population to determine the frequency of polymorphisms of the nuclear factor-kappa (NF-κB1) and NF-κBIA genes, which have been shown to be related to several inflammatory diseases and cancer pathogenesis. Total genomic DNA was isolated from peripheral blood samples taken from 565 healthy volunteers living in Aydin Province. The genomic regions in question were amplified by PCR, and the polymorphisms in these regions were detected by a PCR-RFLP assay. The frequencies were 10.3% for the NF-κB1 -94ins/delATTG del/del genotype, 49.1% for del/ins, and 40.6% for ins/ins. The genotype frequencies of the NF-κBIA 3'UTR A [arrow right] G genotypes were A/A 19.2%, A/G 42.3%, and G/G 38.5%. Distribution of genotype frequencies was tested by Hardy-Weinberg; the NF-κB1 gene was in Hardy-Weinberg equilibrium (χ^sup 2^ = 3.402, P > 0.05), the NF-κBIA gene was not (χ^sup 2^ = 8.293, P < 0.05).[PUBLICATION ABSTRACT]
