IFITM1 and adrenoleukodystrophy: Our present findings in X‐ALD identified the differential methylation in the DMRs of the immune‐associated genes IFITM1 and CD59. Interestingly, the IFITM1 gene, which is overexpressed in X‐ALD, belongs to the interferon signature pathway and plays a role in the host defense against intracellular bacterial/viral infection.
