Children's Study Initiative

Devoted to Children with Learning Disabilities

Genetic, developmental and environmental attributes may contribute to the deficits in learning ability. Recent studies have suggested that phonological awareness is linked to chromosome 6 and ability to identify single words has been linked to chromosome 15. Children with extremely low birth weight and prematurity are at higher risk for developing learning disorders. 35 – 45% of boys and 20% of girls with reading disability had a positive family history.
