An interesting link has been reported between type 2 diabetes (T2D) and CCDC13, a centriolar satellite protein required for ciliogenesis and genome stability (Staples et al., 2014); recent work suggests that primary cilia are important for islet β-cell glucose sensing, calcium influx, insulin secretion, and cross regulation of α and δ cells (Hughes et al., 2020). This evidence concerns the gene INS and type 2 diabetes mellitus.
