In addition, the BCDIN3D locus is associated with obesity and type II diabetes (Berndt et al, 2013; Reinsborough et al, 2021; Thorleifsson et al, 2009; Walley et al, 2009), suggesting a broader but unknown function in human diseases. The gene discussed is BCDIN3D; the disease is obesity due to melanocortin 4 receptor deficiency.
