Four out of the five most strongly associated genes in the GSEA of the GWAS study for relative hand skill in the dyslexia cohort are involved in ciliogenesis: meiosis-specific nuclear structural protein 1 (MNS1), regulatory factor X 3 (RFX3), GLI family zinc finger 3 (GLI3), as well as PKD2 (Figure 2, Table 1) [37]. The gene discussed is RFX3; the disease is dyslexia.
