[PMID 21488903] Association of single nucleotide polymorphisms in the diamine oxidase gene with diamine oxidase serum activities. "Diamine oxidase [DAO] serum activity was significantly associated with seven SNPs within the DAO gene" but "were not associated with the HIT [histamine intolerance] phenotype per se".
Found reduced DAO activity for the minor allele of:
Found moderate protective effect for:
Found lower promoter activity for the minor allele of:
Found lower DAO mRNA expression for the homozygous minor allele of:
