Figure 1. Pedigree of a family with
individuals affected by bilateral congenital cataract. The pedigree of
an autosomal dominant congenital cataract (ADCC) family shows three
members in two generations as affected (filled squares and circle). The
proband (III:2), who was diagnosed as bilaterally affected with
congenital cataract at the age of seven years, is indicated with an
arrow. His elder sister (III:1) was diagnosed with bilateral cataract
when she was six years old. The affected father (II:3) of these
children underwent cataract extraction in both of his eyes in the first
decade of his life.
