SLC6A20 and obesity due to melanocortin 4 receptor deficiency: However, in patients with obesity (BMI ≥30), increased risk of severe COVID-19 was observed for the rs17713054 SLC6A20-LZTFL1 (risk allele A, OR = 2.31, 95% CI = 1.52–3.5, p = 0.0002, pbonf = 0.0004), rs12610495 DPP9 (risk allele G, OR = 1.48, 95% CI = 1.09–2.01, p = 0.01, pbonf = 0.02), and rs17078346 SLC6A20-LZTFL1 (risk allele C, OR = 1.72, 95% CI = 1.15–2.58, p = 0.01, pbonf = 0.02) (Table 4).
