A child is more likely to have downs syndrome if the parents are over 40 years old.
Assuming that the probability of having a baby girl is 1/2 and that of having a baby boy is 1/2, the probability of having 3 baby girls in a row is (1/2)(1/2)(1/2)=1/8.
Unless one has translocation (inherited) Down syndrome than No, they more than likely Won't.
There's a 50% chance the baby will have it too.
the odds of having a baby with beckwith weidemann syndrome is 1 in 13,700 in the united states. that is 300 per year.
Yes. Quite commonly Down syndrome is diagnosed or highly suspected before birth. Prenatal ultrasound can be used to increase the suspicion of Down syndrome by evaluating the nuchal lucency during the 1st trimester. The triple screen (HCG, AFP, and estriol) can also point to a potential chromosomal abnormality. An amniocentesis or chorionic villus sampling can clinch the diagnosis by allowing prenatal chromosomal analysis.
Experts recommend genetic counseling for persons with a family history of Down syndrome who wish to have a baby. A woman's risk of having a child with Down syndrome increases as she gets older. The risk is significantly higher among women age 35 and older. Couples who already have a baby with Down syndrome have an increased risk of having another baby with the condition. Tests such as nuchal translucency ultrasound, amniocentesis, or chorionic villus sampling can be done on a fetus during the first few months of pregnancy to check for Down syndrome. The American College of Obstetricians and Gynecologists recommends offering Down syndrome screening tests to all pregnant women, regardless of age.
