A Single Nucleotide Polymorphism (SNP) in the gene coding for the Zn transporter SLC30A8 (rs13266634) has been identified as being associated with increasing the risk of developing type 2 diabetes (T2D); as such, modification of Zn requirements was hypothesized as a potential method to reduce the risk of T2D for rs13266634 carriers [12,13]. Here, SLC30A8 is linked to type 2 diabetes mellitus.
