Pedigrees of the 23 Japanese families with RP1-associated retinal dystrophies. Five families (Families 1 to 5) with autosomal dominant retinitis pigmentosa (RP), 11 families (Families 6 to 16) with autosomal recessive RP and 7 families (Families 17 to 23) with autosomal recessive cone dystrophy/cone-rod dystrophy. Square boxes and circles indicate males and females, respectively. Filled symbols represent affected members, whereas unfilled symbols represent unaffected members. The plus sign denotes the wild-type allele, and the arrow indicates the proband of the family.
