For diseases other than CAH, GR gene haplotype-phenotype associations studies were performed in various cohorts of children and adults receiving GC treatment: acute lymphoblastic leukaemia [19], cystic fibrosis [20], bowel inflammatory disease [21], psoriasis [22], multiple sclerosis [23], and in Cushing’s [24], metabolic [25] and Guillain Barré [26] syndromes. This evidence concerns the gene NR3C1 and multiple sclerosis.
