Edwards Syndrome Research Paper
Edwards Syndrome, also known as Trisomy 18, is a genetic syndrome of severe to profound mental retardation. It is caused by the presence of an extra chromosome 18 in some or all of the cells in the body. Babies with this condition typically do not survive but for a few months after birth. About sixty percent of newborns with this condition die within the first week, and eighty percent do not survive through the first month. Trisomy 18 in a fetus or embryo is also a common cause of pregnancy loss.

Trisomy refers to a cell that contains three of the same chromosome, Trsiomy 18 then refers to three chromosomes of number

Some physical defects of the heart, skeleton, brain, kidneys, and body walls have a good chance of bein detected by prenatal ultrasound. Women carrying a fetus with Edwards Syndrome sometimes report that they feel little movement. Cesarean sections are more common due to abnormal fetal positon or fetal distress near term.

Of those babies with Edwards Syndrome that are live-born, two-thirds are delivered several weeks early or late. Another common effect is low birth weight. Newborns are frail, and tend to have a weak cry and difficulty feeding. Muscles may be poorly developed, and often become tight and contracted. Extra hair on the forehead and back is sometimes seen, as is loose, redundant skin.

Abnormalities of the lungs, kidneys, pancreas, and spleen are also associated with Edwards Syndrome. Anomalies of the breastbone, ribs, pelvis, and the spine are the more frequent skeletal findings. An abdominal wall defect or hernia in the abdominal region may be present, and in some cases genital anomalies in both maled and females are not

Diseases w/ Autonomic - dominant inheritance in the parents, such as Tuberous Sclerosis and Basal - Cell Nevus Syndrom, sould be excluded. It is important to search for fetal Infection ( TORCH). Regular sonografic checks DO NOT show any changes in the finding, but the associated VENTRICULOMEGALY may develop later in pregnancy.…

    A type of birth defect that affects the skeletal system is Spina Bifida. Spina Bifida is a nueral tube defect that occurs when the bones of the spine or the vertebrae do not form accurately around the spinal cord. In severe cases it can inhibit a persons walking or daily activities. There are three basic forms of Spina Bifida. The mildest form is Occulta, the next would be Meningocele and the most severe is Myelomeningocele. (http://www.uptodate.com/contents/overview-of-the-management-of-myelomeningocele-spina-bifida 2012) Myelomeningocele is the case that affects the skeletal system the most.

    DiGeorge syndrome is an anomaly that occurs when the 22q11.2 chromosome has been deleted, causing many different symptoms in various parts of the body. Those affected by DiGeorge syndrome often display signs of heart disease and defect at birth, presence of "cleft" palate (opening in the roof of the mouth), learning disorders, autoimmune diseases (such as rheumatoid arthritis), hypocalcaemia (low presence of calcium in blood), speech disabilities, and sometimes growth disorders. This syndrome is not explicitly fatal, but cardiac disorders caused by the DiGeorge syndrome are its greatest cause of mortality. Diseases contracted from severe immunity deficiency can also lead to death. It has…

    Williams Syndrome is caused by a deletion of genes in the Williams-Beuren region of chromosome 7; when deletions occur during the formation of the egg and sperm, it is caused by unequal recombination during meiosis. Recombination normally occurs between pairs of chromosomes during meiosis while they are lined up at the metaphase plate. If the pairs of chromosomes don't line up correctly, or if the chromosome breaks aren't repaired properly, the structure of the chromosome can be altered. Unequal recombination occurs more often than usual at this location on chromosome 7, causing Williams syndrome.…
