Objective:
To examine the association of single nucleotide polymorphisms (SNP) in the NFKB1 gene, as well as 2 genes in the nuclear factor (NF)-kappaB functional complex (RelA and NFKBIA), in patients with psoriatic arthritis (PsA) from Newfoundland.
Methods:
Patients with PsA and controls were genotyped for one 4-base insertion/deletion and 5 SNP in NFKB1, 4 SNP in RelA, and 7 SNP in NFKBIA by time-of-flight mass spectrometry, using the Sequenom platform. Chi-square analysis was used to test the single locus associations between SNP in the NF-kappaB complex and PsA. Associations between multi-locus haplotypes and case or control status were tested using the software PHASE.
Results:
Two hundred and twenty-four patients with PsA (52% male) and 88 ethnically matched controls (64% male) were genotyped. No association was noted with any of the SNP tested for the single locus associations in NFKB1, RelA, and NFKBIA or with multi-locus haplotypes. In particular, the allele frequency for the NFKB1 -94delATTG was 41.7% in cases and 41.6% in the controls (p = 0.97).
Conclusion:
No association between the NFKB1 -94 ins/delATTG promoter polymorphism or with other NF-kappaB complex SNP in patients with PsA from Newfoundland was observed.
