Progeria Resources: Learn More About Girls Featured in '7 Going on 70'

Sept. 10, 2010— -- Barbara Walters reports on Lindsay Ratcliffe, Kaylee Halko and Haylee Okines, three vibrant young girls who suffer from progeria, an extremely rare and fatal disease characterized by rapid aging in children. It is rare; of every 4-to-8 million births worldwide, only one baby will have progeria, according to the Progeria Research Foundation. So far, 68 children around that world currently have been identified and diagnosed with progeria. On average, children with the disease die at age 13.
