Genes associated with neuronal migration and dyslexia, such as ROBO1, DCDC2, DYX1C1, and KIA0319, KIA0319, which are linked to neural cell migration and dyslexia, and genes such as CTNNB1, TCF7L2, and KIF3A, which are associated with insulin secretion regulation and glucose transport and type 2 diabetes, are all involved in the WNT signaling pathway. Here, DNAAF4 is linked to type 2 diabetes mellitus.
