In addition, IL-1RN was also associated with body mass index (BMI) in READ, with higher expression in individuals who were underweight, obese, or overweight (median = 21.9, 13.4, and 11, respectively) and lower expression in individuals with normal weights (median = 9.8) (p = 3.4 × 10−2) (Figure 6B, Table 8). The gene discussed is IL1RN; the disease is reading.
