ZNRD2 and type 2 diabetes mellitus: SNPs associated with the expression levels of genes including EHHADH (rs7431357), SSSCA1 (rs1194076), and P2RX4 (rs2071271) in eQTLGen were not significant in the T2D meta-analysis, likely due to the lack of power; these SNPs were expected to be detected in future studies with larger sample sizes.
