ACE2 and obesity due to melanocortin 4 receptor deficiency: Lower adipose tissue ACE2 expression was associated with multiple adverse cardio-metabolic health indices, including type 2 diabetes (T2D) (P = 9.14 × 10−6), obesity status (P = 4.81 × 10−5), higher serum fasting insulin (P = 5.32 × 10−4), BMI (P = 3.94 × 10−4), and lower serum HDL levels (P = 1.92 × 10−7).
