EYS and autosomal recessive retinitis pigmentosa: The eyes shut homolog (EYS; OMIM: 612424) is a major disease-causing gene for autosomal recessive retinitis pigmentosa, and is mainly found in Chinese and Japanese populations (Pontikos et al., 2020), where it has a prevalence ratio of about 11% (Abd El-Aziz et al., 2010; Xiao et al., 2019) and 32.8% (Hosono et al., 2012; Iwanami et al., 2012; Arai et al., 2015; Yang et al., 2020), respectively.
