Figure 1. Pedigree of families PKGL005 and PKGL025. Squares denote males, circles indicate females, filled symbols represent affected individuals, double lines between individuals indicate consanguinity, and a diagonal line through a symbol signify that the family member is deceased. The haplotypes of 15 adjacent chromosome 14q14.2–24.3 microsatellite markers for families PKGL005 (A) and family PKGL025 (B) are shown with alleles forming the risk haplotype shaded black, alleles cosegregating with primary congenital glaucoma (PCG) but not showing homozygosity shaded gray, and alleles not cosegregating with PCG shown in white.
