SYMPTOMS OF TURNER SYNDROM Medically Reviewed Short stature; one of the missing genes in the “X” chromosome is the SHOX gene. This gene is responsible for the long bone growth development; “more than 95% of adult women with Turner syndrome exhibit short stature”. Without it‚ your bones don’t grow the way they should; average adult height with Turner syndrome is 4 feet 7 inches. “Scoliosis affects the spine and occurs in 10% of young girls with Turner syndrome

DiGeorge Syndrome: A Study in Chromosomal Errors 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

Jacob’s syndrome 2 Anatomy and Physiology: Jacob’s syndrome Over the past 40 years people have been aware of Jacobs’s syndrome‚ a rare chromosomal genetic syndrome which occurs when a male receives an extra Y chromosome‚ resulting in a sequence in XYY. Males normally have XY and females normally have XX sequencing 1. Chromosomes store genetic information in all human beings. There are 23 pairs of chromosomes and 46 in total. On the 23rd pair holds the sex chromosomes which also store genetic information

Klinefelter’s Syndrome “Harry Fitch Klinefelter specialized in endocrinology and rheumatology (weak bones) and through his studies Klinefelter’s syndrome was described in 1942‚” (Encyclopedia Britannica). The diagnosis of the patient is usually done at a young age through a series of many tests‚ one in which the doctor finds if the patient has two X-Chromosomes and one Y-Chromosome. As a random genetic mishap during the formation of the fetus‚ Klinefelter’s has many symptoms. The treatment is not

Sex Chromosomes Introduction Few people every wonder or care about their gender and why they are male or female.. Sex-determination system is a complex but fascinating progress‚ especially within reptiles‚ birds and insects. All living organisms begin with one eukaryotic cell; inside the nucleus of each cell contain thread-like structures called chromosomes. Chromosomes are once theorized to be derived from autosomes (chromosomes that are not sex chromosomes) and have changed into specific

The three that I chose to discuss‚ not only peak my interest‚ but are also disorders that I plan to work with in the future: Klinefelter Syndrome‚ Fragile X Syndrome‚ and Downs Syndrome. All three disorders impair those that they affect‚ in mental‚ cognitive and physical

What is Klinefelter syndrome? Klinefelter syndrome is a chromosomal condition that affects male sexual development. Males with this condition typically have small testes that do not produce enough testosterone‚ which is the hormone that directs male sexual development before birth and during puberty. A shortage of testosterone during puberty can lead to breast enlargement (gynecomastia)‚ reduced facial and body hair‚ and an inability to father children (infertility). Older children and adults with

Klinefelter’s Syndrome is a genetic condition that is only found in males and the male is born with an extra copy of the X chromosome. It was first diagnosed by Dr. Harry Klinefelter and his coworker in 1942. They did a group research of men who had the symptoms of Klinefelter syndrome. By late 1950‚ Dr.Klinefelter discovered that the men with Klinefelter syndrome had an extra sex chromosome making them XXY instead of a normal male XY. “Klinefelter’s syndrome occurs in about 1 in 500-1000 male births

However‚ sometimes embryos are formed with too many or too few chromosomes‚ which is known as aneuploidy. Embryos with aneuploidy may be born with conditions like Down syndrome or Trisomy 21. In other cases‚ aneuploidy results in a miscarriage. Preimplantation genetic screening can determine if an embryo has the correct number of chromosomes to develop into viable pregnancy and a healthy baby. Not only

been key to many cancer advancements in this world. Research on yeast cells shows that certain cells are predestined to evolve into cancer cells. One study found that aneuploidy in cells lead to genomic instability and that this genomic instability correlated to an elevated rate of cancer development. (Sheltzer et al‚ 2011) Aneuploidy as well results in recombination defects and defective DNA repair which again in many cases leads to cancer. (Sheltzer et al‚ 2011) When these cells are identified in
