A: The pedigree of Family 4. Filled symbols represent affected, unfilled unaffected, dotted carrier. Square signify male, circles females. Arrow marks the index patient. M refers to the mutant allele, and + means normal allele. B–C: Fundus photographs of the 42-year-old proband (V:1) showed bone spicules like pigmentation, attenuated blood vessels, waxy pallor of the disc and RPE degeneration. D: Representative sequence chromatograms for a normal individual (left), a female mutation carrier (middle) and a male patient (right).
