Figure 1. Schematic of rhodopsin protein and location of mutations. Yellow dots represent the position of previously published ninaE alleles used in this study. Red dots represent novel alleles of ninaE. The genetic change and corresponding allele names are as following: P84L, ninaE^R11; S95F, ninaE^D2; P120L, ninaE⁵; S137F, ninaE^D1; S177L, ninaE^R12.
