Solute carrier family 30 (zinc transporter), member 8, also known as SLC30A8, is a human gene[1] that codes for a zinc transporter related to insulin secretion in humans. Certain alleles of this gene may increase the risk for developing type 2 diabetes, but a loss-of-function mutation appears to greatly reduce the risk of diabetes.[2]

Clinical significance

Association with type 2 diabetes (T2D)

12 rare variants in SLC30A8 have been identified through the sequencing or genotyping of approximately 150,000 individuals from 5 different ancestry groups. SLC30A8 contains a common variant (p.Trp325Arg), which is associated with T2D risk and levels of glucose and proinsulin.[3][4][5] Individuals carrying protein-truncating variants collectively had 65% reduced risk of T2D. Additionally, non-diabetic individuals from Iceland harboring a frameshift variant p.Lys34Serfs*50 demonstrated reduced glucose levels.[2] Earlier functional studies of SLC30A8 suggested that reduced zinc transport increased T2D risk.[6][7] Conversely, loss-of-function mutations in humans indicate that SLC30A8 haploinsufficiency protects against T2D. Therefore, ZnT8 inhibition can serve as a therapeutic strategy in preventing T2D.[2]
