  1. Sequencing of the 5' upstream promoter region of pooled genomic DNA confirmed the presence of two common genetic variants in the ALOX5 promoter: rs12762303 T>C and a 6 bp deletion of the tandem repeat sequence GGGCGG, in addition to a single common SNP in the TGFβ1 promoter: rs1800469 T>C. Common SNPs and their positions in the 5' promoter region are shown according to nucleotide numbering in the ensembl database and by the authors who first described the promoter regions for ALOX5 (Hoshiko et al, 1990) [66] and TGFβ1 (Kim et al, 1989) [48]. Pooled DNA sequencing only detects common polymorphisms (> 10–15% of sample) [30].
