Down syndrome is a genetic condition that typically causes some level of learning disability and a characteristic range of physical features.
Most babies born with Down's syndrome are diagnosed with the condition after birth and are likely to have: reduced muscle tone leading to floppine eyes that slant upwards and outwards a below average weight and length at birth

People with Down's syndrome also vary in personality and ability. Everyone born with Down's syndrome will have a degree of learning disability. The level of learning disability will be different for each individual.
