What do we mean by “genetic and developmental disabilities”? A. As a group, disabilities that occur prior to birth, during birth, or in very early childhood. B. These include (not a complete list!) 1. Mental retardation—affects about 1% of the population. MR can be categorized as a) Mild mental retardation (Intelligence Quotient, or IQ score of 50 to 70). About 85% of people with MR have mild mental retardation. b) Moderate mental retardation (IQ of 35 – 50) c) Severe mental retardation (IQ from 20 – 40) d) Profound mental retardation (IQ below 20) 2. Down Syndrome—born with three, rather than two, copies of the 21 st chromosome. This is the most commonly occurring genetic condition, affecting all ethnic and nationality groups. Children with DS usually fall within the mild to moderate range of mental retardation. Often Down syndrome is associated with some impairment of cognitive ability and physical growth as well as facial appearance.
