Prevalence of FUT2 and FUT3 alleles and genotypes in severe and mild patient groups.

FUT2 and FUT3 allele frequencies and genotypes, and resultant phenotypes were consistent with that known for the Caucasian population. [27] There is no association between lung disease severity in patients homozygous for the ΔF508 mutation and individual FUT2 or FUT 3 SNPs, nor with secretor or Lewis status. § P-values generated by Fisher exact test.
