The results of additional analysis showed that SLC25A21‐AS1 expression was significantly reduced in patients with obesity (body mass index [BMI] > 28) in the GSE53625 dataset and in overweight patients (BMI: 24–27.9) in The Cancer Genome Atlas TCGA (Figure S2C). Here, SLC25A21 is linked to obesity due to melanocortin 4 receptor deficiency.
