Figure 1. Pedigree drawing and haplotypes of chromosome 7q markers of family PKCC108. Squares are males, circles are females, and filled symbols are affected individuals; the double line between individuals indicates consanguinity and the diagonal line through a symbol is a deceased family member. The haplotypes of 11 adjacent chromosome 7q microsatellite markers are shown; alleles forming the risk haplotype are shaded black, while alleles not co-segregating with cataract are shown in white.
