Figure 2. The distribution of CNGB3 causative variants in our cohort. The CNGB3 c.1663–1205G>A variant is the most common (34.4% out of all CNGB3 pathogenic alleles), whereas the panethnic mutation, c.1148del, has been identified in 28.6% of alleles. The letter “n” represents the number of alleles identified in affected individuals, and this number is followed by their proportion among CNGB3 mutated alleles.
