The Role of Heredity in Reading Disability.
Delker, Laryl Lee
A clinical and genetic analysis was made on the basis of 52 families: 27 were from reading clinics where at least one child in the family had been diagnosed as having a reading disability; 25 were families of children selected from a third-, fourth-, or fifth-grade class on the basis of having average or above-average IQ and achievement. Through the use of a questionnaire a summary was made of specific reading disability characteristics found in the families and the students. It was found that a larger number of males than females was affected with a reading disability. Birth order did not appear to be a contributing factor. Only one family was present where both parents had a reading disability; both of their children were affected with a reading disability. In the families where one parent was affected with a reading disability, Weinberg's method of Mendelian Analysis was used, giving a value of 37.7 percent of their children being affected. Chi-square analysis indicated that the value of 37.7 percent is not significantly different from the theoretical 50 percent expected in a single hybrid autosomal dominant mode of inheritance. Thus it was concluded that a relationship between heredity and specific reading disability was shown. Other biochemical findings, tables, and a bibliography are included. (Author/DH)
