KRT4 and keratoconus: Accordingly, we investigate the number of editing sites that impacted the keratin type II cluster between KC and CT (Fig. 3C), resulting similarly for KRT1, KRT2, KRT6A, KRT75, and KRT77, but higher in KC for KRT4, KRT5, KRT6B, KRT6C, KRT7, KRT7-AS, KRT76, KRT78, KRT79, and KRT84, whereas it was lower in KC only for KRT3.
