IGF2BP2 and cystic fibrosis-related diabetes: In 2013, Blackman et al., using genome-wide association and candidate gene-based approaches, confirmed association with the TCF7L2 gene and identified four new loci associated with CFRD: CDKAL1, CDKN2A/B, IGF2BP2, also associated with T2D [110], and SLC26A9, specific to CFRD [110].
