How Genetics Influence Down Syndrome Julia Henry PSY 104 Professor Vincent July 7‚ 2013 How Genetics Influence Down Syndrome Genetics play such an vital role in our development. Every individual carries genes from their mother and their father. Characteristics such as height‚ eye color‚ if we have curly or straight hair are all determined through the our genes and specifically our chromosomes. Many times‚ parents inadvertently pass genes on to their children through their DNA that may contribute

Angelman syndrome (AS) is an infrequent genetic condition that has a considerable impact on a person’s nervous system which causes them to have severe physical and intellectual disabilities; I will briefly define these in the commentary (Genetic Disorders‚ 2015). Harry Angelman identified the condition in three children in 1965 however in today’s research it is found in one in sixteen million people.(Angelmanuk.2015).Therefore the reason the research has been so motivational is due to it being very

Tourette’s is an inherited disorder‚ and it’s believed that it is closely linked to damage of the basal ganglia or the brain. The tics are classified as simple or complex. Simple tics are sudden

Ehlers-Danlos Syndrome Ehlers-Danlos Syndrome (EDS) is an inherited connective tissue disorder that is classified into six distinct primary types. EDS was first described around the turn of the century by Eduard Ehlers‚ a Danish physician‚ and Henri-Alexandre Danlos‚ a French physician. Before 1997 there were ten recognized types of EDS that were labeled with Roman numerals I through X. Once doctors had more experience with patients with EDS and as technology improved to study biochemical

Turner’s Syndrome Turner’s syndrome is a genetic condition in which a female does not have the usual pair of two X chromosomes. This medical disorder affects about 1 in every 2‚500 girls. I do not know exactly what causes Turner syndrome‚ but researchers know that it is the result of a problem with a girl ’s chromosomes either not being there at all or only part of it is still there. I think the most known effects of the condition vary widely with girls with Turner syndrome. It all depends

Zellweger syndrome is one of a group of four related diseases called peroxisome biogenesis disorders‚ a group of deadly genetic diseases that claim the lives of children usually before they reach their first birthday. This syndrome is the most common type of peroxisome biogenesis disorder. The disease is caused by defects in any one of 13 genes‚ called PEX genes‚ required for the normal formation and function of peroxisomes. Peroxisomes are cell structures that break down toxic substances and synthesize

Aspergers Syndrome is a lifelong neurobiological disorder of social interaction and behavior (Frith 2004; Wing 1981; Gillberg and Gillberg 1989; Klin et al. 2000). The purpose of this study was to study the language performance in school-aged children with Aspergers Syndrome along with their age‚ sex‚ and IQ matched controls. Prior to the study‚ they expected children with Aspergers Syndrome to perform below average in the selected measures of language due to their difficulties in language development

Down Syndrome Although many theories have been developed‚ it is not known what actually causes Down syndrome. Some professionals believe that hormonal abnormalities‚ X-rays‚ viral infections‚ immunologic problems‚ or genetic predisposition may be the cause of the improper cell division resulting in Down syndrome. It has been known for some time that the risk of having a child with Down syndrome increases with advancing age of the mother; i.e.‚ the older the mother‚ the greater the possibility
