COGA pedigree 10022. The 11 individuals with black shading were considered to be affected, the unshaded individuals in the last 2 generations (857, 191, and 658) were considered unaffected, and the gray individuals were treated as unknown. There was no available information about the phenotypes or genotypes of the 3 distinct founders in the first generation (268, 997, and 221). Note: The 2 circles in the first generation that are marked with an arrow represent a single individual.
