down syndrome is a genetic disorder caused by the presence of an extra chromosome in the body cells
Answers
There can be impairments in cognitive ability and physical growth, mild to moderate developmental disabilities, and a higher risk of some health problems.
Through a series of screenings and tests, Down syndrome can be detected before or after birth.
The likelihood having Down syndrome is around 1 in every 700 pregnancies. It is determined by many factors, but research suggests there is a higher risk if the mother delivers at over 35 years of age.
Before the age of 30 years, fewer than one in 1,000 pregnancies will be affected by Down syndrome. After the age of 40 years, this figure rises to about 12 in 1,000.
Down syndrome is a genetic condition that results when there is an extra copy of a specific chromosome, chromosome 21.
It is not an illness but a term that describes the features resulting from this change.
The extra chromosome can affect the physical features, intellect, and overall development of an individual.
It also increases the likelihood of some health problems.
