We found SNP rs1800470 in TGFB1 (OR = 1.255, P = 0.0004) and rs1800796 (OR = 0.84, P = 0.0228) in IL-6 to be significantly associated with DDH in this cohort.
Data suggest association between TGFB1 29 T → C transition (rs1800470) and IL6 -572G → C transversion (rs1800796) with DDH, and also a possibility of TGF-beta1 and IL-6 interaction in DDH pathogenesis.
