A genome-wide association study by Hawcutt et al. also reports that single nucleotide polymorphisms within the platelet-derived growth factor D (PDGFD) gene locus could be associated with an increased risk of developing corticosteroids-induced adrenal suppression in children with asthma and adult with chronic obstructive pulmonary disease (COPD) [73]. The gene discussed is PDGFD; the disease is chronic obstructive pulmonary disease.
