To date, mutations in three genes have been identified as causing Stargardt disease, including ATP-binding cassette, subfamily A, member 4 (ABCA4), elongation of very long chain fatty acids-like 4 (ELOVL4), and cyclic nucleotide-gated channel, beta-3 (CNGB3) [1-3]. This evidence concerns the gene CNGB3 and Stargardt disease.
