Mutations in C8orf37 can also cause non-syndromic retinal degeneration including cone–rod dystrophy (CRD, MIM 120,970, cone–rod dystrophy 16 (CORD16) [3,4,5]) and retinitis pigmentosa (RP, MIM 268,000, retinitis pigmentosa 64 (RP64) [3,6,7,8,9]). This evidence concerns the gene CFAP418 and retinitis pigmentosa 1.
