Individual case reports have described other unique CRX-associated retinopathy phenotypes, including occult macular dystrophy [12], as well as phenotypes resembling benign concentric annular macular dystrophy [13], pigmented paravenous retinochoroidal atrophy [14], X-linked retinoschisis [15], benign concentric annular macular dystrophy [16], and macular coloboma-like lesions [17,18]. Here, CRX is linked to X-linked retinoschisis.
