Similarly, the Kir channel KCNJ13 (Kir7.1) has been reported to be linked to snowflake vitreoretinal degeneration and Leber congenital amaurosis in humans (Hejtmancik et al. 2008; Sergouniotis et al. 2011), cleft palate and tracheal tubulogenesis in mice (Villanueva et al. 2015; Yin et al. 2018), and pigmentation pattern changes in zebrafish (Iwashita et al. 2006). This evidence concerns the gene KCNJ13 and Leber congenital amaurosis.
