Several studies in the past decade have associated mutations in the human CDHR1 gene with cone-rod dystrophies (Bolz et al., 2005; Henderson et al., 2010; Ostergaard et al., 2010; Cohen et al., 2012; Duncan et al., 2012; Ba-Abbad et al., 2013; Bessenyei and Oláh, 2014; Nikopoulos et al., 2015; Arno et al., 2016; Riera et al., 2017; Stingl et al., 2017; Fu et al., 2018). The gene discussed is CDHR1; the disease is Rod-cone dystrophy.
