Abstract Background Crohn’s disease (CD) is a chronic inflammatory disorder belonging to the inflammatory bowel diseases (IBD). CD affects distinct parts of the gastrointestinal tract, leading to symptoms including diarrhea, fever, abdominal pain, weight loss, and anemia. The aim of this study was to assess whether the DNA methylome of peripheral blood cells can be associated with CD in women. Methods Samples were obtained from 18 female patients with histologically confirmed ileal or ileocolic CD and 25 healthy age- and gender-matched controls (mean age and standard deviation: 30.5 ± 6.5 years for both groups). Genome-wide DNA methylation was determined using the Illumina HumanMethylation 450k BeadChip. Results Our analysis implicated 4287 differentially methylated positions (DMPs; corrected p
