One of the most common genetic diseases is Trisomy 21, or better known as, Down Syndrome. “Every year, around 6,000 babies are born with Down Syndrome.” (What is Down Syndrome?). Down Syndrome is a genetic disorder in which there are three copies of chromosome 21. In each nucleus of every cell in each human, there are 23 pairs of chromosomes, 46 chromosomes all together. In a Down Syndrome person, there are three strands of chromosome 21. This causes many defects in that person. Some of the physical traits of Down Syndrome are slanting eyes, small stature, and a crease down the center of the palms of their hands. Each person is different and this is why there are a wide variety of degrees of these defects. Humans reproduce by meiosis. Meiosis is when two diploid cells come together and create four haploid cells. These cells have 23 chromosomes. When a sperm cell and an egg unite, they create a diploid cell with 46 chromosomes, 23 pairs of chromosomes. Sometimes, there is a mix up when the cells meet which causes there to be three copies of chromosome 21. Some of these mix ups are nondisjunction, when the chromosomes do not separate properly, or translocation, which is when another copy of chromosome 21 attaches to another part of a chromosome. There is another type of Down Syndrome called Mosaic Down Syndrome. “A very small percentage of people with Down syndrome have an extra copy of chromosome 21 in only some of the body’s cells. In these people, the condition is called mosaic Down syndrome.” (Down Syndrome – Genetics Home Reference). I thought this was interesting. All of our cells in our body contain the same DNA. How could some cells have an extra copy of chromosome 21 and some be normal? There are ways to find out if the baby a mother is carrying is going to have Down Syndrome. There is a prenatal test that can determine if the baby could have Down Syndrome. A blood test is done during the first trimester of pregnancy. They check for certain proteins that could suggest Down Syndrome. After they draw the blood, they do an ultrasound to see if there is fluid in the back of the baby’s neck, which is an indicator for Down Syndrome. Before these tests are done, the parents have to be questioned whether they want to have these tests done because they could be harmful to the baby. “Prenatal diagnostic testing does involve some risk to the mother and fetus, including risk of miscarriage that ranges from less than 1% to 2%.” (How Do Health Care Providers…).If the baby is likely to have Down Syndrome, more tests have to be done. Some tests include taking fluid for the amniotic sac and seeing if there is an extra part of chromosome 21. The parents can see if their child will have Down Syndrome, or at least the likelyhood of the baby having a physical and mental defect. This can raise some questions morally for the parents. If parents know that their child will be mentally handicapped, they could choose to abort the child. This is the wrong choice. Killing a baby, no matter how small and no matter having a defect, is morally wrong. The baby is a their child that they should love no matter what because the baby is made up of the mother’s and father’s DNA. Even though their child will be mentally handicapped, the parents should be willing to take care of their child and give him or her whatever they need. Down Syndrome is a genetic disorder, which means that it is in the genes and the DNA. It is not usually a hereditary disease. The only proven cause of Down Syndrome is the age factor of the mothers. It is more common when the mothers are older in age. There is no other cause that has been proven yet. People who have Down Syndrome are mentally handicapped. They learned slower than others without Down Syndrome. There is a wide range of the severity of some learning defects. Some children or people develop great social skills and some take a while to obtain these skills. They learn better when they can visually see the things they are learning. Down Syndrome people can learn to read, which helps develop their language and words. They like to use symbols and arm gestures as a way to communicate. Their motor skills take awhile to develop which affects their oral skills too. One of the most common defects is their language. “Children with Down syndrome show specific delays in learning to use spoken language relative to their non-verbal understanding. Almost every child will have expressive language that is delayed relative to their language comprehension.”(Development and Learning). They struggle to talk and speak correctly. They also seem to struggle with numbers and short term memory. Overall, people with Down Syndrome need help with everything everyday. My cousin is mentally handicapped. She is one of the friendliest and kindest people you will ever meet. She just graduated high school and now is working at a simple job where her strengths can be portrayed. However, she was not born with this. People with Down Syndrome are not given a chance to live a normal life and that is a sad thing to think about. It is a genetic disease that is determined during fertilization. “Everyone who has Down syndrome was born with it and will always have it. Down syndrome affects people from all around the world, and both boys and girls can be born with it. Approximately one in 700 babies born in the United States has Down syndrome.” (What Is Down Syndrome?). That is a lot of children who will never have a normal life, but that does not make them less of a person. People with Down Syndrome are happy and they laugh, even though they will have good days and bad days. They are as much people as we are. Down Syndrome is a genetic disease that affects many families and their children all around the world. It can not be healed or fixed. It cannot be prevented. It is a mistake in nature, but the child is never a mistake. I have been on the Pro-life March in Washington D.C. two times now. We march to end abortion and the murder of babies. No matter what the baby’s condition is, the parents should never have the right to kill their child because they are always loved. Down Syndrome is a very hard thing to carry in a family. It takes strong parents, family members, and children to overcome the hardships of Down Syndrome because it is not easy. They have many emotions that take a really strong person to handle. Overall, Down Syndrome is a genetic disorder that affects many lives, yet can still bring happiness to families.
