However, the only common DMR associated gene between CVID_N, CVID_IEL and celiac disease compared to controls, was SLC6A19 (location in chr5 between position 1,203,001 and 1,204,000, mean methylation difference 28.9%, 1408 base pairs away from the transcription start site) (Supplementary data 4). Here, SLC6A19 is linked to celiac disease.
