One BS-DMP mapping to the AHRR/EXOC3 locus (cg25648203, BH-Padj < 0.05) overlapped with smoking-associated DMPs previously reported in whole blood from MS patients.14 Interestingly, cg25648203 displayed increased effect size in BAL cells compared to blood (ΔβBAL = −0.251 vs. Δβblood = −0.052; Supplementary Table 3). Here, AHRR is linked to myeloid sarcoma.
