Figure 1. Pedigree drawing and haplotypes of chromosome 1p markers of family PKCC118. 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 12 adjacent chromosome 1p microsatellite markers are shown; alleles forming the risk haplotype are shaded black, while alleles not co-segregating with cataract are shown in white.
