Question
Is it definitely Down syndrome if a baby has a mouth that’s often half-open, a round and flat face, small eyes, a low bridge of the nose, a tongue that frequently protrudes, shorter limbs?
Answer
Down syndrome, also known as mongolism, is a congenital birth defect disease caused by chromosomal abnormalities. Infants with this condition are born with distinctive facial features, including a small and round head, wide-set eyes, narrow eyelids, a low bridge of the nose, and other characteristics, along with intellectual disability and delayed motor and sexual development. Although your description resembles the symptoms of Down syndrome, diagnosis cannot be made solely based on symptoms; peripheral blood cell chromosome analysis is necessary for confirmation.
