The role of ALOX5AP, LTA4H and LTB4R polymorphisms in determining baseline lung function and COPD susceptibility in UK smokers.

ABSTRACT:

Background

We have previously shown evidence that polymorphisms within genes controlling leukotriene B4 (LTB4) production (ALOX5AP and LTA4H) are associated with asthma susceptibility in children. Evidence also suggests a potential role of LTB4 in COPD disease mechanisms including recruitment of neutrophils to the lung. The aim of the current study was to see if these SNPs and those spanning the receptor genes for LTB4 (LTB4R1 and LTB4R2) influence baseline lung function and COPD susceptibility/severity in smokers.

Methods

Eight ALOX5AP, six LTA4H and six LTB4R single nucleotide polymorphisms (SNPs) were genotyped in a UK Smoking Cohort (n = 992). Association with baseline lung function (FEV1 and FEV1/FVC ratio) was determined by linear regression. Logistic regression was us
