Hayashi and co-workers (2020) reported two additional cases of patients with overlapping phenotypes of cone-rod dystrophy (CORD3) and Nougaret-type congenital stationary night blindness (CSNBAD3), carrying biallelic ABCA4 variants (p.(Gln185Ter) and c.1760 + 2T > G) alongside a heterozygous dominant GNAT1 variant (p.(Gly38Asp)) [18]. This evidence concerns the gene ABCA4 and cone-rod dystrophy.
