The cause of Down syndrome is a chromosomal abnormality. It is typically caused by the presence of an extra copy of chromosome 21, resulting in a total of three copies instead of the usual two copies. This condition is known as trisomy 21 and is responsible for the characteristic features and developmental issues associated with Down syndrome. It is not caused by maternal use of caffeine, an inherited genetic condition, or poor parental nutrition.
