Using existing Chromatin Interaction Analysis by Paired-End Tag sequencing (ChIA-PET) data (Table 1), Kehayova et al. identified physical interactions between the locations of osteoarthritis mQTL CpGs identified in adult cartilage tissue and the 3′ untranslated region of COLGALT2, subsequently confirming this as an osteoarthritis effector gene through functional analysis [37]. Here, COLGALT2 is linked to osteoarthritis.
