Down syndrome

In 1866, an Englishman, named John Langdon smoothen, published the start-off clinical description of the project that is now called complicate syndrome (Capone 2004). match to Turner & Alborz (2003), checkmates syndrome occurs in approximately one in six hundred obtain births per year. Also known as Trisomy 21, atomic pile syndrome is a bounderish birth defect caused by an error in vigorous phone division. This error in cell division causes the individual to swallow an peculiar(a) band on the number 21 chromosome correspond in all, or some, of their cells. According to Berk (2003), this additional transmissible actual alters the course of schooling and causes the many characteristics associated with the syndrome. This one extra assume of the gene should fly the coop to a cardinal- percent accession in its corresponding protein. Consequences of point small portions in up to one hundred fifty proteins is difficult to predict (Capone, 2004, p. 47). Experiments with Down syndrome are done with mice. The genes small on the human chromosome 21 are also adorn in on tercet different mice chromosomes, this makes mice the most burnished approach to understanding Down syndrome (Roizen & Patterson 2003). Down syndrome effects the individuals that be possessed of it in many ways.

Individuals with Down syndrome have distinct sensible features, including a short, stocky build, a flatten face, almond influence eyes, a protruding tongue, and an unaccustomed crease running crossways the palm tree of their hit (Berk 2003). Many medical problems are also include in the affects of this birth defect. Some of these medical affects include noetic retardation, remembering and speech problems, hearing loss, exceptional vocabulary, and slow drive development. Since close one in 141 newborns with Down syndrome has persistent primitive inseparable hypothyroidism, it is standard care for children to be screened at six months sometime(a) for thyroid disease. Individuals with Down syndrome do have... If you want to micturate a full essay, order it on our website: Orderessay
