According to the U.S. National Institutes of Health, the overall rate of incidence of Down Syndrome is 0.13% (1 in 750); but this figure is misleading since the incidence is highly related to the age of the mother. For mothers below age 30, the incidence of Down Syndrome is 0.10% (1 in 1000); but it increases dramatically after age 30. At age 41, the risk of giving birth to a Down Syndrome child is 10 times the risk at age 30. Mother's age 30 -- incidence 0.11% (1 in 900) Mother's age 35 -- incidence 0.25% (1 in 400) Mother's age 40 -- incidence 0.95% (1 in 105) Mother's age 42 -- incidence 1.7% (1 in 60) Mother's age 44 -- incidence 2.9% (1 in 35) Mother's age 46 -- incidence 5.0% (1 in 20) Mother's age 48 -- incidence 6.3% (1 in 16)
The incidence, however, increases dramatically with increasing maternal age. If you look at the link below, under about age 30, there is a 1:1000 chance in having a child with Down syndrome, however, at age 40, there is about a 1:100 chance. This increases to 1:10 by age 50.
80% of all children with Down syndrome are born to women under the age of 30, however, because women of this age group have children at a much higher rate than those over 30.
Approximately 0.1% of babies are born with Down syndrome. This number may vary slightly depending on factors such as maternal age.
Approximately 1 in 800 people, or .12%, which is around 340,000 people.
1 in every 1,000 babies that is born. 1 is the Down syndrome and 1,000 is the people that dont.
Approximately 1 in 15,000 - 20,000 babies is born with Angelman syndrome, making it a rare genetic disorder.
World-wide, over 5.8 million people have Down syndrome. (This condition affects people of all ages, races, religions and economic situations.)Approximately 1 in every 1,000 babies has Down syndrome.In the UKIt is estimated that there are about 60,000 people with Down syndrome living in the UK. About 600 babies with Down syndrome are born in the UK each year.
About 14 babies a day, which is approximately 5,000 a year in the US.More parents are choosing now to have their Down baby born, rather than terminate the pregnancy, due to better health care and social programs, and disabilities are more accepted now in our society.
* Down syndrome, caused by trisomy of the 21st chromosome, overall is seen in about 1 in 750 live births. The incidence, however, increases dramatically with increasing maternal age. If you look at the link below, under about age 30, there is a 1:1000 chance in having a child with Down syndrome, however, at age 40, there is about a 1:100 chance. This increases to 1:10 by age 50. 80% of all children with Down syndrome are born to women under the age of 30, however, because women of this age group have children at a much higher rate than those over 30. * Approximately 1 in 800-1,000 babies are born with Down syndrome. * The overall incidence of Down's syndrome is 1 in 660 newborns, thereby making it the most common pattern of malformation in man. === === * According to scientific data, Down syndrome occurs in 1 out of every 750 births.
1 in every 1,000 babies that is born. 1 is the Down syndrome and 1,000 is the people that dont.
Approximately 1 in 15,000 - 20,000 babies is born with Angelman syndrome, making it a rare genetic disorder.
Babies are born with an extra chromosome.
The official statistic in the US is 1 per every 733 live births; this equals approximately 5,429 babies born with Down syndrome each year.
Down syndrome is something you are born with; it is not something that will suddenly "appear."
World-wide, over 5.8 million people have Down syndrome. (This condition affects people of all ages, races, religions and economic situations.)Approximately 1 in every 1,000 babies has Down syndrome.In the UKIt is estimated that there are about 60,000 people with Down syndrome living in the UK. About 600 babies with Down syndrome are born in the UK each year.
While a precise number is unknown, it is estimated that over 400,000 people in the United States have Down syndrome. Out of every 691 babies born in America, 1 is born with Down syndrome.
chromosome translocation got it right from study island if that is what you are using it for. good luck on future questions
its congenital disease meanz babies r born with it..10 to 15 percent have down syndrome and it is more common in boys
You do not "get" Down's syndrome. You are born with it. It is a chromosomal condition of the 21st chromosome.
No. Down's syndrome is a chromosomal disorder. In order to have it you have to be born with it.
Nobody really knows exactly what causes Down Syndrome. Down Syndrome is a condition where a baby is born with an extra chromosome in their DNA. There is some evidence that says having a baby at an older age (40 and above) may have a higher risk of having a Down Syndrome baby. Taking medicines cannot cause you to develop Down Syndrome, because it's something you are born with; however, taking addictive drugs while you are pregnant does cause serious damage in the unborn baby, and many babies born to alcoholics and drug addicts have brain damage. There is a possibility that Down Syndrome could occur if the chromosomes are damaged.
