Figure 1. Pedigrees of 12 families with mutations and cosegregation results for those mutations. The family members and their corresponding mutations are shown just above the pedigrees (M, mutated allele; +, wild-type allele). Squares indicate male individuals, and circles indicate female individuals. The patients with arrows were the probands in these families.
