The protein encoded by Scd1 is responsible for converting long‐chain saturated fatty acids to monounsaturated fatty acids (Ntambi et al, 2002), and elevated gene expression has been observed in visceral adipose tissue in humans with both obesity and T2D (Eissing et al, 2013). The gene discussed is SCD; the disease is obesity due to melanocortin 4 receptor deficiency.
