The results indicated that 5 protein coding genes, including CCR10, HLA-DRB4, LENG8, QRFPR, and UHRF1BP1, were shown significant differences between obesity non-OA and obesity OA samples (Figure 4(a)), while the remaining genes had no statistic difference between these two groups. Here, QRFPR is linked to obesity due to melanocortin 4 receptor deficiency.
