For example, very recently, Dwivedi et al. (2019) demonstrated that a rare loss-of-function allele, p.Arg138*, in the SLC30A8 gene encoding the zinc transporter 8 (ZnT8), which is enriched in Western Finland, protects against type 2 diabetes (T2D) [46]. The gene discussed is SLC30A8; the disease is type 2 diabetes mellitus.
