Down syndrome

Down syndrome is one of the most common genetic disorders. Down syndrome is a genetic disorder where a person is born with an extra copy of chromosome 21. Down syndrome is a form of mental retardation. In the United States about 4,000 children are being born with this condition annually. One in about every 900 births is effected, making it the most common birth defect. There are three genetic variations that cause this disorder: trisomy 21, Mosaic Trisomy 21, or Translocation Trisomy 21. There…

Patients with Down Syndrome can present with a variety of oral manifestations such as hypodontia, periodontal disease, premature teeth loss, reduced salivary flow, crowding of teeth in both arches, and decreased occlusal vertical dimension. The intellectual ability of people with Down syndrome varies widely. They present with mild to moderate intellectual disability that restricts their ability to communicate and adjust to their environment, which can add complexity in the overall dental…

DOWN SYNDROME: A LIFE-LONG DISORDER Imagine facing two choices: parents having to abort their unborn baby, or they go through the pregnancy knowing their child is going to have Down syndrome, knowing that raising him or her will not be easy. Many parents face this choice everyday. According to Peggy Parks, author of Down Syndrome, 80 to 90 percent of unborn babies diagnosed with Down syndrome are aborted (19). Everyday, all around the world babies are diagnosed with Down syndrome and parents…

ichael explains his case in a creative way. He has Down syndrome when the chromosomes came to make him, a normal chromosome broke, the broken piece moved and struck onto another chromosome.Its called spontaneous translocation.No one knows why this happens or how to prevent it. He starts to talk like how he is like everyone else. All he does is learns things a different way. It takes him longer to process information and form his thoughts and communicate with others. He gets frustrated when…

What Is It? Down syndrome is a mutation caused when cell division is abnormal and results in one extra copy of chromosome 21. Originally forming in egg cells, and not passed on genetically but as a mutation, Down Syndrome is known as the disorder that occurs when an extra copy of the twenty-first chromosome is made during formation of the egg and sperm. Down syndrome is a lifelong condition in which a person is born with distinct physical features and some degree of cognitive disability. Since…

Down syndrome Down syndrome is one of the many disorders that affect hundreds of thousands of people around the world. Down syndrome, also known as Trisomy 21, occurs when an extra copy of the 21 chromosome is made. The disorder usually causes several impairments that can range from mild to severe; impairments include both mental and physical aspects of the individual. Presently, there is no full cure for Down syndrome, but there are numerous of treatments options and way to enhance the…

Did you know that Downs’ syndrome is a condition or a syndrome, not a disease? How about the fact that it is the most commonly occurring chromosomal condition? There is a lot more to Downs’ syndrome than people think. There are many fascinating facts about this condition that are not in the common knowledge! Downs’ syndrome is a genetic disorder which is caused by an error in cell division that results in the presence of an extra copy of chromosome 21. Most of the time the error occurs at…

Down syndrome Down syndrome is a genetic disorder that may alter the development of individuals. Each person that is diagnosed with Down syndrome is unique in their own way. Some may develop some of the most common characteristics associated with this disorder. According Sietske N. Heyn, PhD, some of the most common characteristics would include mild to moderate learning disabilities, distinctive facial features, and low muscle tone. However, not every person who is diagnosed with Down syndrome…

Down syndrome (DS) is a condition where extra genetic material causes issues in the way a person develops, both mentally and physically. The physical features and medical problems associated with Down syndrome can vary widely depending on each different person. While some people with DS need a lot of medical attention, others live healthy and normal lives. Though Down syndrome can't be prevented, it can be detected before a child is born. The health problems that may go along with DS can be…

Trisomy 21 is the congenital disorder better known as Down syndrome. This occurs when each cell has three copies of chromosome twenty-one rather than having a normal pair. Nondisjunction is "an error in which homologous chromosomes or sister chromatids fail to separate normally during meiosis or mitosis" (Huether, McCancep, 2012, p.42). Therefore, a common cause of Down syndrome is nondisjunction. Scientists have made the discovery that Down syndrome is caused by an extra chromosome, but the…
