Down syndrome

chromosomal condition characterized by flat-looking facial features and weak muscle tone (hypotonia) in infancy and is caused by trisomy of all or a critical portion of chromosome 21 and is associated with intellectual disability

Down syndrome or Down's syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is usually associated with physical growth delays, mild to moderate intellectual disability, and characteristic facial features. The average IQ of a young adult with Down syndrome is 50, equivalent to the mental ability of an eight- or nine-year-old child, but this can vary widely.
