We also tested whether the heritability of BMI and other obesity-related traits, including serum triglycerides (TGs), alanine aminotransferase (ALT), blood glucose levels, LDL and total cholesterol, systolic blood pressure (BP), and forced vital capacity (FVC), are enriched in the PAd A compartments. Here, GPT is linked to obesity due to melanocortin 4 receptor deficiency.
