Figure 1. Pedigree drawing and chromosome 17p13 haplotypes of two familes. (A) family 61032 and (B) family 61227. Squares are males, circles are females, filled symbols are affected individuals, double line between individuals
indicates consanguinity and diagonal line through a symbol is deceased family member. The haplotypes of 7 adjacent chromosome
17p13.2 microsatellite markers are shown. Alleles forming the risk haplotype are shaded black, alleles co-segregating with
RP but not showing homozygosity are shaded grey, and alleles not co-segregating with RP are shown in white.
