Down Syndrome A Congenital Chromosomal Disorder

Down syndrome is a congenital chromosomal disorder during maternal meiosis. This is one of the most common chromosomal disease that has been confirmed (Epstein, 2013). Down syndrome causes some symptoms in children’s physical and mental aspects, which have significant differences with other people. It may cause the life of the child is abnormal and cannot live independently in the future. With the increased population of children with Down syndrome in Australia, it becomes prominent that they strongly impact on their family and society in both positive and negative ways. This article will introduce some basic information about Down syndrome, discuss its early intervention and ethical issues of having a baby with Down syndrome, and result in coming up with views in regards to terminating or continuing with the pregnancy of a foetus diagnosed with Down syndrome. Down syndrome is also called 21 trisomy, which is obviously pointed out the disorder occurs at the chromosome 21. Genetically, it has been found that there are 22 pairs of autosomes and one pair of sex chromosomes, where X and Y are sex chromosomes representing female and male respectively. These two kinds of chromosome pairs are normally made up 46 chromosomes in total while children with Down syndrome have 47 chromosomes, meaning they have one extra chromosome on the chromosome 21. This chromosomal disorder happens occasionally and randomly. One cannot put blame or fault on the individual or parent when the gene isShow MoreRelatedEssay on Cystic Fibrosis1025 Words   |  5 Pages Cystic Fibrosis is a disorder where the exocrine glands secrete abnormally thick mucus, leading to obstruction of the pancreas and chronic infections of the lungs, which usually cause death in childhood or early adulthood. Some mildly affected patients may survive longer. Doctors can diagnose the disease by testing the patients perspiration because people with Cystic Fibrosis have high amounts of salt in their perspiration. Those with respiratory infections are treated with antibioticsRead More Down Syndrome Essay603 Words   |  3 Pagesresulting in the birth of a child with a genetic or congenital defect or disease. One of the most common of these genetic disorders is Down syndrome. This disorder takes its name from Dr. Langdon Down, who was the first to describe it formally, in 1866. Down syndrome is a condition marked by abnormal physical and mental development that is caused by a genetic defect. This genetic defect is caused by an extra chromosome. People born with Down syndrome have 47 chromosomes compared to the normal amountRead MoreCongenital Condition Of Congenital Heart Defects1188 Words   |  5 PagesINTRODUCTION Congenital Heart Defects (CHDs) include all structural anomalies of the heart and the intrathoracic great vessels resulting from the errors in morphogenesis, during development. The incidence of CHDs among live births is estimated to be 3.7 to 7.7 per 1000 (Ferencz et al. 1985). CHDs are etiologically heterogenous and it could be due to genetic (single gene defects, chromosomal abnormality) and or environmental (multifactorial, teratogens) or unknown factors (Michels and RicardiRead MoreDown Syndrome As A Cognitive Disorder Essay1315 Words   |  6 Pages Down syndrome as a cognitive disorder Down syndrome (DS) is relatively well known as a genetic disorder to the general public and children with this syndrome form one of the most readily identifiable groups of children with moderate to severe learning difficulties. It has been over 130 years since Langdon Down first described DS and 30 years since the presence of the defining extra copy of chromosome 21 was identified by Lejeune andRead MoreThe Disorder Of Down Syndrome1431 Words   |  6 Pagesever wonder or questioned the disorder of down syndrome? According to many National Down Syndrome Society within the United States, Down syndrome has occurred one out of eight hundred births. It is the most frequent form of mental retardation and characterized by well-defined events and distinctive features. It’s a lifelong disorder caused by a genetic defeat that’s none curable. It takes people with patients and kind hearts to care for people with Down syndrome disorder. History In the late nineteenthRead MoreDown Syndrome Essay1515 Words   |  7 PagesDown Syndrome Downs Syndrome, it is one of the most frequently occurring chromosomal abnormalities found in humans effecting people of all ages, races and economic levels. It is a chromosomal anomaly in cell development that results in a person being born with forty-seven chromosomes instead of the normal forty-six chromosomes. People with Down syndrome may have mild to severe learning disabilities and physical symptoms, which include a small skull, extra folds of skin under the eyes, andRead MoreThe Discovery Of Down Syndrome874 Words   |  4 PagesDown syndrome is a common disorder where the child gets an extra copy of the 21st chromosome. It happens in every 691 babies born in the United States. This adds up to about 6,000 babies born with the disorder a year. The major points in this paper are: when the disorder was discovered, the symptoms, the lifespan, the medical treatments, if it is a dominant trait, what chromosome is affected, and how it is passed down to offspring. The discovery of Down syndrome was by an English physician namedRead MoreGenetic Disorders : A Genetic Disorder954 Words   |  4 Pages A genetic disorder is an illness that is caused by one or multiple abnormalities in the genome. Genetic disorders are not unusual, however when a genetic disorder occurs it usually happens in one and every thousand or million persons. Sometimes genetic disorders can or cannot be heritable, meaning passed down from the parents to their offspring. Often times the parents are unaware that they can carry over a genetic disorder to their offspring. When genetic disorders that does not occur from theRead MoreHistory of the Patau Syndrome1850 Words   |  7 PagesPatau Syndrome, otherwise known as T13 is a very rare and lethal genetic disorder in which a person has three copies of chromosome 13 instead of two. T13 is characterized by the presence of an assortment of heart and brain malformation in newborns. Children with the disease are often born with multiple birth defects that are normally associated with T13 but not limited to it, including small eyes, undescended testicles, cleft lip/palate, and they consistently exhibit signs of mental deficiency and/orRead MoreCongenital Diseases : Congenital Disease1210 Words   |  5 PagesCongenital disease Congenital disease (birth defect) are defects of any kind that are present at birth. However, not all are caused by a mutation in the DNA. Another way to say congenital disorder are birth defects. Congenital disease is where it â€Å"occurs at birth or even before birth†¦the incidence is 2~5% in newborn and the percentage of congenital disease related to genetic or chromosome defects was 60~70%.; the other 30% of etiology was unknown†¦ congenital disease can be categorized into chromosome
