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]. Here, SLC24A1 is linked to autosomal recessive retinitis pigmentosa.
