Objectives:
Fas/FasL is significantly involved in the pathogenesis of rheumatoid arthritis (RA). Fas/FasL gene polymorphism may be associated with susceptibility to rheumatoid arthritis and disease severity.
Aim:
To investigate the Fas 670 G/A and FasL 843 C/T genotype and allele frequency in patients with RA, and determine its potential association with susceptibility to the disease and the clinical parameters.
Methods:
One hundred and one patients with RA and 105 healthy control subjects were enrolled in the study. Fas 670 A/G and FasL 843C/T genotype polymorphism was investigated by PCR-RFLP. Chi-square test was used for determining the genotype distribution and the allele incidence.
Results:
There was no statistically significant difference between the patients with RA and the healthy subjects with respect to Fas-670 A/G and FasL-843C/T genotype distribution and allele frequency (P>0.05). While there was no statistically significant difference in disease severity and various clinical parameters, a correlation was detected between Fas-670 polymorphism and anti-CCP antibody and anemia (P<0.01 and P<0.03, respectively).
Conclusions:
Fas-670A/G and FasL-843C/T promoter gene polymorphisms are not considered to represent a major genetic risk factor for RA susceptibility and disease severity. However, based on these results, Fas-670 promoter polymorphism may modulate anti-CCP antibody synthesis and response in patients with rheumatoid arthritis.
