 ""...Most individuals with Down syndrome have mental retardation in the mild (IQ 50–70) to moderate (IQ 35–50) range,[3] with individuals having Mosaic Down syndrome typically 10–30 points higher."" 

 I think that IQ 70-85 is considered ""mild retardation,"" while IQ 50-70 is considered ""moderate"" and less than IQ 50 is regarded as ""profound."" This should be checked and, if appropriate, amended.   00:05, 17 July 2009"
