ABSTRACT
BACKGROUND: Functional macrophage migration inhibitory factor (MIF) gene polymorphisms are associated with elevated serum levels of MIF and increased susceptibility to various autoimmune diseases. MIF levels in the sera of pemphigus vulgaris (PV) patients are increased; however, no definite association has been demonstrated between PV and MIF gene polymorphisms. The present study was conducted to ascertain any association between MIF-173*G-C and MIF-794*CATT5-8 polymorphisms and PV.
METHODS: Seventy-five patients with PV and 252 healthy, unrelated, voluntary controls were enrolled randomly in the study. MIF-173*G-C polymorphism (rs755622) was genotyped using polymerase chain reaction (PCR) followed by restriction fragment length analysis, and MIF-794*CATT5-8 (rs5844572) was genotyp ed using PCR followed by capillary gel electrophoresis. Subsequently, the allelic, genotype, and haplotype frequencies were determined and compared for both groups. Data were also analyzed with respect to sex, age at onset, type of disease, and duration of disease.
RESULTS: No significant association was observed in terms of allelic, genotype, and haplotype frequencies of MIF gene polymorphisms in PV patients. However, a significantly lower prevalence of the C allele (P=0.02) and CATT7 allele (P=0.03) was seen in our patient population compared to healthy controls. Analysis of the effect of various factors such as gender, age at onset, type of disease, and disease duration revealed no significant association with the genetic variants.
CONCLUSIONS: MIF-173*G-C and -794*CATT5-8 polymorphisms are not associated with PV.
