Figure 5. Pedigree structure of family 1 and its haplotype analysis at PPCD1 locus

This family was originally used to map PPCD to the chromosome 20 locus [6]. No VSX1 mutation has been identified in this family. Marker names are shown on the right. Genotypes of each individual are shown as numbers underneath the individual's symbol. Dark bars represent the inferred disease haplotype with recombinations of parental chromosome shown.
