Who is at a higher risk for down's syndrome and what is the chromosomal abnormality?

Question

Just wondering

Answer 1

Who is at risk for Down syndrome?

The chance of having a baby with Down syndrome increases as a woman gets older—from about 1 in 1,250 for a woman who gets pregnant at age 25, to about 1 in 100 for a woman who gets pregnant at age 40.  But, most babies with Down syndrome are born to women under age 35 because more younger women have babies.  

Because the chances of having a baby with Down syndrome increase with the age of the mother, many health care providers recommend that women over age 35 have prenatal testing for the condition.  Testing the baby before it is born to see if he or she is likely to have Down syndrome allows parents and families to prepare for the baby’s special needs.

Parents who have already have a baby with Down syndrome or who have abnormalities in their own chromosome 21 are also at higher risk for having a baby with Down Syndrome.

Once the baby is born, a blood test can confirm whether the baby has Down syndrome.

What is Down Syndrome?

Down syndrome is set of mental and physical symptoms that result from having an extra copy of Chromosome 21.  

Normally, a fertilized egg has 23 pairs of chromosomes.  In most people with Down syndrome, there is an extra copy of Chromosome 21 (also called trisomy 21 because there are three copies of this chromosome instead of two), which changes the body’s and brain’s normal development.

Answer 2

Also, the age of the male counts. Information released just this year revealed that sperm health decreases as a man ages debunking the theory about men's sperm being healthy for life. I read this in the Daily Herald newspaper in Health and Fitness a few months ago. I'm sure there is something on it from the CDC or just about anything health and development related. My parents were 40 (mother) and 52 (father) when I was born and I have autism. There is a risk as both parents age for kids to be born with developmental disabilities like Down's and autism.

Most of the people I knew with downs were female. I don't know if this is general. Chromosomal was about 21
