The Influence of Maternal Age on Down syndrome Children born to older parents are at greater risk for genetic abnormalities, such as Down syndrome. No one knows what causes the chromosomal abnormality that results in Down syndrome, a condition according to the National Association for Down syndrome, affects one in 800 to 1,000 babies in the United States. Any woman regardless of her culture, race and socio-economic status can have a baby with Down syndrome. However, a mother’ age seems to be a unifying factor among children with Down syndrome. Older women have a greater chance of giving birth to a baby with Down syndrome, and the risks increases with every passing year. The National Association for Down syndrome estimates the chance of having a baby with Down syndrome to be as follows: Less than 1 in 1,000 for a woman below age 30 Approximately 1 in 400 for a 35-year-old woman Approximately 1 in 105 for a 40-year-old woman Approximately 1 in 20 for a 46-year-old woman History of Down Syndrome In 1886, physician John Langdon Down was the first scientist to identify Down syndrome. Down was the administrator of a mental institute for children in Surrey, England. From his observations and work at the institute, he was able to identify a set of children who exhibited characteristics such as short nose, broad flat face, short and broad hands, which are features commonly identified with Down syndrome. He later wrote an essay entitled “Observations of the Ethnic Classification of Idiots” in which he asserts the notion that it was possible to classify different types of health conditions through race. His essay included his now famous classification of what is today known as Down syndrome, which he categorized as the Mongol... ... middle of paper ... ...1994;330:1114–8. 16.

The child that I tested will be referred to as K.L. I tested her on April 14th 2016. K.L. is 2 years old, with her exact age being 2 years 9 months and 14 days. I called and asked her mother if she would mind dropping K.L. off with me for a few hours so I could perform the test, and then pick her back up after the test was complete. This test more accurate when the caregiver is not present. K.L. has a step sister and a baby brother on the way. She has always been in the daycare setting, because her grandmother is a provider. K.L. was delivered full term via planned cesarean section due to her mother’s small pelvis. There was no complications during this pregnancy. K.L. weighted 8 lbs. 4 oz. and was 20 ½ inches long at birth, now weighting in at ...
second, prenatal testing, is a testing of a fetus at risk for the disease. The
An individual who has Down syndrome can be recognized as different from others since he or she have different physical features, but the question is, what causes individuals to have deformed face, little different features than someone who does not have Down syndrome? The reason some individuals are born with Down syndrome is because of an extra chromosome, this chromosome, which carries number 21. It is also known as Trisomy 21. Having this sort of disability, does not truly affect their life in a way they are not able to live, but it affects their cognitive levels, their physical growth of the child with Down syndrome. As the mother goes for an ultra sound, doctors can detect that the child within the mother’s womb has Down syndrome. (1) Mothers over age 35 have higher risk of giving birth to a child with Down syndrome, and 1 in every 1,000 women at the age of 30. In addition, in every 100 women, who age 40 there is a mother has a child with this case. As woman ages there is a higher chance of conceiving a child with Down syndrome than a woman who is in her mid-20s or younger. (2) This essay will highlight the effects and supports of Down syndrome in children.
Down syndrome is a genetic disorder, associated with the presence of an extra chromosome. Downs is characterized by mild to severe mental impairment, weak muscle tone, shorter stature, and a flattened face. Down syndrome is not a very common disease, one in every 691 children are born with Down syndrome. The disability is an illness that people are born with and is not contagious. Most people with Downs have a life expectancy of about 40 or 50 years of age. They only live for that short amount of time because they begin to develop a similar disease to Alzheimer’s. “100% of people with Down syndrome will develop some physiologic signs of Alzheimer’s when they are over 35 years old in the U.S” (Statistics about Down Syndrome). They also die earlier because having Down syndrome increases the risk of leukemia 15-20 times in the US. Therefore most people with Downs will die because of leukemia or heart problems before the age of 50.
Another technology that has been around for a while is the general ultrasound. In the article by Jennifer Wang she states, “The risk of a patient having a fetus with Down syndrome can be assessed non-invasively using fetal markers seen on ultrasound.
Down syndrome, a genetic disorder, is the most common cause for intellectual disabilities, occurring at an average of one out of every 700 births (CDS, 2006). This disorder is caused by the extra chromosome 21 (also known as Trisomy 21). According to Hassold and Sherman (2002), the probability of giving birth to a child with DS is not linked to any race, ethnicity, socioeconomic status or geographic location. Maternal age seems to be the only etiological factor that may cause DS.

Prenatal genetic testing has become one of the largest and most influencial advances in clinical genetics today. "Of the over 4000 genetic traits which have been distinguished to date, more than 300 are identifiable via prenatal genetic testing" (Morris, 1993). Every year, thousands of couples are subjecting their lives to the results of prenatal tests. For some, the information may be a sigh of relief, for others a tear of terror. The psychological effects following a prenatal test can be devastating, leaving the woman with a decision which will affect the rest of her life.

Would you want to know the health of your child before it is born? That is what Prenatal Testing is for. If you don’t know what it is exactly, you’ll learn as you read through this paper. The two types of prenatal testing are prenatal screening and prenatal diagnosis. Both types of testing allow for pregnant women to have a clearer understanding of their child. (Prenatal Diagnosis 2015) New ways of learning about the fetus will most likely become available in the near future because of technology advancing everyday. Even though some people believe miscarriages are a problem with some of the testing that’s done, it’s okay for pregnant women to do prenatal testing to make sure their baby is healthy because there could be possible disorders in the baby, results from the testing can help, and the tests can find cancer in pregnant women.
