Mutations in at least one gene from each family have previously been associated with retinal disease: Klhl7 with autosomal dominant RP [56], Slc24A1 with autosomal-recessive congenital stationary night blindness [57], and Znf513 with autosomal-recessive retinitis pigmentosa (RP) [58]. This evidence concerns the gene KLHL7 and autosomal recessive retinitis pigmentosa.
