X chromosome

Klinefelter Syndrome Michael Santiago Definitions Klinefelter syndrome - is a chromosomal condition that is a result of the nondisjunction of the chromosomes. It usually affects the male physical and cognitive development. It is characterized by an extra X chromosome. Signs and symptoms vary for each individual. It affects different stages of physical, language, and social development. It is considered as the most common sex chromosome disorder. Etiology Klinefelter syndrome is caused by an error that results in a male to be born with an extra sex chromosome. Each cell of the human body contains 46 chromosomes, two of which determines a person’s sex. Females have two X chromosomes (XX) while males have an X and a Y chromosome (XY).…

their spine is curvature surgery may be needed (Mayo Clinic, 2014). Epidemiology: Duchenne muscular dystrophy approximately affects 1 of every 5,600 to 7,700 males between the ages of 5 - 24. Females are very rarely affected by DMD, and will not have the dramatic signs like the males do. Although if they are carriers of the mutated chromosome, they possibly will experience small symptoms of weakness in their muscles. However there were cases reported where a female’s second chromosome is…

Duchenne Muscular Dystrophy In this world, there are many diseases that are being caused by the X chromosomes or the Y chromosomes. Some of the diseases could be passed down from generation onto the next because it is gene and some of the diseases can be treated and which later on causes for it to make it worse. The diseases that would always be there would be Down Syndrome, Huntington’s Disease, Hemophobia, and many more. As you can see, this paper is going to be able a genetic disease that is…

Turner Syndrome “Turner syndrome is a medical disorder that affects about a in every 2,500 girls.” Says Teens Health. Many people today are effected by genetic diseases, “a genetic disease is a disease that is caused by an abnormality in an individual’s DNA.” says Genetic Science Learning Center. A genetic disorder is not inherited but instead caused by a mutations in an individual’s DNA. These diseases shape who people are and affect them and the people around them their whole lives. There…

day, I struggle knowing I have a genetic disorder; Turner Syndrome. Turner Syndrome, or TS, is a genetic, chromosomal disorder in which a female is born with only one X chromosome (the 23rd pair). This affects the development in women (the disease can only occur in women). The most common way a female can get TS is by monosomy, which means an X chromosome is completely…

of an extra X chromosome at conception. It occurs in one in every 500-1000 male births but the rate is up to 20 times higher in newborns. It was first discovered in 1942 by a doctor named Klinefelter who published case reports of nine men who had breast enlargement, a lack of facial and body hair, smaller than average testicles and an inability to produce sperm. There are medical researchers that realized the role of the extra X chromosome and confirmed it to be the causative factor. Treatments…

SIMULATION CROSS BETWEEN A HETEROZYGOUS FEMALE AND A HEMOPHILIA MALE BACKGROUND INFORMATION The survival of the human species throughout the last millions of years has been solely based on the randomized process of genetic inheritance from one generation to the next generation. Instead of duplicating their genetic information and create identical offspring, humans produce sex cells, through the process of meiosis, that carry only half of the genetic information, and fertilize them in order to…

What if you were already ten years old and just now were diagnosed with a syndrome that could have been found close to 10 years ago. Turner syndrome affects "1 in 2,500 every newborn girl," in the U.S. Turner syndrome is when a female has one working X-chromosome and one is altered or missing. The many symptoms include short stature, webbed neck and lymphedema, which is swelling of the hands and feet. To find out if you or a female you know has turner syndrome testing includes a lab test of…

Pigmentosa for 20 years, Eric A. Pierce, a ophthalmologist, found out that what part of the chromosome goes wrong will cause the RP happened. In the experiment, he first looks for the mice that have the RP, and take out their genes to compare to the candidate genes from human. Then, they matched them and used the conventional molecular genetic technique to find out that the RP1 gene on…
