DNMT3B and food allergy: We limited our analysis to all SNPs genotyped on the array within a heuristic 10-kb window up and downstream of the core set of 24 differentially remodeled genes25, as well as within genes encoding the de novo DNA methyltransferase enzymes DNMT3A and DNMT3B and previously published food allergy SNPs annotated in the genome-wide association study and SNPedia catalogs5,26.
