Is Down syndrome caused by mother or father?
Human cells normally contain 23 pairs of chromosomes. One chromosome in each pair comes from your father, the other from your mother. Down syndrome results when abnormal cell division involving chromosome 21 occurs.
What are the 4 main causes of birth defects?
Researchers think that most birth defects are caused by a complex mix of factors, which can include:

Who is mostly affected by Down syndrome?
Eighty percent of children with either trisomy 21 or mosaicism Down syndrome are born to mothers who are younger than 35 years old. Younger women have babies more frequently, so the number of babies with Down syndrome are higher in that group.
Can you fix Down syndrome in the womb?
The extra chromosome can’t be removed from cells, so there’s no cure for the condition. The chromosomes divide incorrectly by accident, not because of anything the parents have done. Although the chance of having a child with Down syndrome increases with the age of the mother, anyone can have a baby with Down syndrome.

Down syndrome occurs at conception, so nothing in the pregnancy can cause Down syndrome to occur. As for prior to conception, the research all shows that drug or alcohol use does not increase the risk of having a child with DS.
Does father’s age affect Down syndrome?
The rate of Down syndrome for both maternal and paternal age greater than 40 years is approximately 60 per 10,000 births, which is a six-fold increase compared with maternal and paternal ages less than 35 years of age.
Can Down syndrome be prevented?
Down syndrome can’t be prevented, but parents can take steps that may reduce the risk. The older the mother, the higher the risk of having a baby with Down syndrome. Women can reduce the risk of Down syndrome by giving birth before age 35.
What are 3 interesting facts about Down syndrome?

- Prenatal screening for Down syndrome is available.
- Other health problems can occur with Down syndrome.
What is the main cause of Down syndrome?
Down syndrome is usually caused by an error in cell division called “nondisjunction.” Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate.

Can you tell if a baby has Down syndrome at 20 week ultrasound?
Diagnosing Down syndrome
It is necessary to look at fetal cells through a microscope to diagnose a chromosomal abnormality. Therefore, chromosomal lesions such as Down syndrome cannot be diagnosed with ultrasound. Some 40% of Down syndrome fetuses will appear normal on the 19-20 week scan.

CDC urges all women of reproductive age to consume 400 mcg of folic acid each day, in addition to consuming food with folate from a varied diet, to help prevent some major birth defects of the baby’s brain and spine (known as neural tube defects).
