Figure 3. Pedigree drawings of family 60067 (A) and 60078 (B) are shown. 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 11 adjacent chromosome 5q31 microsatellite markers are shown with alleles forming the risk haplotype are shaded black, alleles co-segregating with phenotype but not showing homozygosity are shaded grey and alleles not co-segregating with disease phenotype are shown in white.
