Kawasaki disease (KD) is characterized as a self-limited systemic vasculitis. C1q/tumor necrosis factor-related protein-1 (CTRP1) had been associated with the occurrence of vasculitis in KD. Methylation at the promoter region of certain genes was reported to be involved in the development process of KD. This study aims to investigate the methylation levels of CTRP1 in KD, as well as, its potential to predict coronary artery aneurysms (CAAs). 31 patients with KD and 14 healthy controls (HCs) were recruited into this study. The KD group was further divided into KD with CAA (KD-CAAs) group and KD without NCAAs (KD-NCAAs) group. Methylation levels of CpG sites were determined by MethylTarget sequencing, a method that uses multiple targeted CpG methylation analysis. The methylation levels of CTRP1 promoter region in the KD group were lower than that in the HC group at all predicted CpG sites, especially at sites 34, 51, 69, 79, 176 and 206. Compared with KD-CAAs group, the methylation levels of almost every CpG sites of CTRP1 were increased in the KD-NCAAs group, with site 69 and 154 found to be strongly related to the occurrence of CAAs. The difference in methylation levels of CTRP1 promoter may be involved in the development process of KD, and may be a potential predictive marker for the occurrence of CAAs. •Methylation levels of CTRP1 are remarkably lower at six CpG sites in Kawasaki disease.•CpG sites 69 and 154 are strongly associated with coronary artery aneurysms.•Combination of sites 69 and 154 has potential to predict coronary artery aneurysms.•14 transcription factors that were predicted may bind to the CpG site at CTRP1 via JASPAR2019.
