The Ala allele at Val762Ala polymorphism in poly(ADP-ribose) polymerase-1 (PARP-1) gene is associated with a decreased risk of asthma in a Turkish population.

It has been suggested that inhibition of poly (ADP-ribose) polymerase-1 (PARP-1), either pharmacologically or by a gene knockout provides significant protection against systemic or tissue inflammation in animal models. The aim of this study was to analyze the association of the PARP-1 Val762Ala polymorphism, which has beenreported to be associated with decreased enzymatic activity, in Turkish patients with adult asthma.
A total of 112 subjects with stable asthma and 180 normal controls from the same geographic region were studied and polymerase chain reaction-based restriction analysis was used to identify Val762Ala polymorphism of the PARP-1.
In univariate analysis, PARP-1 762 AA genotype conferred a 3.4 fold reduction in risk (OR = 0.297, 95% CI = 0.105-0.813; P = 0.014), while heterozygous VA genotype conferred an even greater level of protection (OR = 0.06; 95%CI, 0.026-0.14; P < 10(-6)). In addition, wild type PARP-1 762 V allele had 5 times the risk of developing asthma than those without the allele (OR 0.199, CI 0.118-0.334, P = 10(-6)).
These findings suggest that PARP-1 V762A variants may be one of the factors participating in protection or susceptibility to asthma in our population.
