Also for hepcidin/TS no significant signals were observed, but for hepcidin/ferritin we identified two signals that reached exome-wide significance: exm470499 in WDR36 (all; p = 9.9x10-7) and exm162358 in MTR (subset; p = 2.7x10-8); variants close to and in these genes have previously been associated with allergy [43] and homocysteine levels [44], respectively. This evidence concerns the gene HAMP and allergic disease.
