Figure 1. Pedigree drawing of families A: PKRP170 and B: PKRP172 with haplotypes of chromosome 5q microsatellite markers. Squares represent male, circles represent female, filled symbols are affected individuals, a double line between individuals indicates consanguinity, and a diagonal line through a symbol is a deceased family member. Alleles forming the risk haplotype (black), and alleles not cosegregating with arCSNB are shown white.
