Klinefelter's syndrome

Klinefelter’s: Stories Needing to be Told Klinefelter’s syndrome affects 1 in every 600 males. Yet, surprisingly, it is often regarded as the “forgotten syndrome.” This is because after being discovered over 70 years ago by Dr. Harry Klinefelter, there are still many cases that go undiagnosed and many males that go untreated. This is due to a lack of public awareness about Klinefelter’s, a disease that everyone can be knowledgeable about when it is presented on an engaging platform such as TedEd. It is time for those who live with this syndrome to get the recognition and attention that they so rightfully deserve. Klinefelter’s belong to a class of diseases known as genetic diseases. Some more well known ones include Down Syndrome, X-linked…

Chromosomes, or strings of genes carrying genetic information, are vital to the existence of living things. A specimen cannot have more or less than how many that particular species needs. In humans, this number is 23. The 23rd pair of chromosomes, referred to as Group X, contain the sex cells that decide the gender of the organism. If a Y chromosome is present, the organism is male, and if not, it is a female. If the chromosomes fail to separate correctly during meiosis (type of cell division…

Klinefelter Syndrome Klinefelter Syndrome is a condition that affects sex chromosomes in males only. It is one of the most common genetic disorders. KS was named after Dr. Harry Klinefelter who was the first person to report it’s symptoms in 1942.(7) Harry was a Endocrinologist from Baltimore working at the Massachusetts General Hospital. Males with Klinefelter’s present with a variation of symptoms from babies to adults. Some symptoms are noticeable and some are unnoticeable. It is common…

Klinefelter Syndrome Klinefelter Syndrome is a disorder in which there is an extra X chromosome to the standard male, 47 chromosomes rather than 46 chromosomes, genetically common to males. David Drexler is a 56 year old man with Klinefelter Syndrome or XXY for short; he was diagnosed with Klinefelter Syndrome at age 19. Mr. Drexler describes that in following with the Syndrome it'll delay puberty too. Drexler childhood was terrible. At the age 18, puberty didn't seem to happen for Drexler,…

Klinefelter’s syndrome (KS) is a genetic condition that can be caused when someone, usually male, has two X chromosomes and one Y chromosome giving them forty seven and not the normal forty six chromosomes. Males normally have an X chromosome and a Y chromosome and females normally have two X chromosomes. When either the sperm or the egg has a pair of sex chromosomes doesn’t succeed in separating formation, thus there is an extra chromosome causing the DNA abnormality during fertilization. This…

Quentin’s physician believes had has Klinefelter syndrome due to his enlarge breast tissue, long limbs, and abnormally small testes. Based on my findings, “Klinefleter syndrome is a chromosomal condition that affects male physical and cognitive development”(Genetics Home, 2015). This genetic disorder is a result of having 2 X and a Y-chromosomes mixed together. Individuals living with Klinefeter syndrome typically have small testes that do not produce as much testosterone as usual”(Genetic Home,…

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…

Down syndrome - People with down syndrome often share the same characteristics of facial features, short stature, shorter lifespan, slower development and learning capabilities. They are often victims to respiratory diseases, early Alzheimer’s, leukemia, vision problems, and hearing defects. This mutation is caused by the mother’s age or the result of nondisjunction in father’s chromosome 21(extra copy of chromosome 21). Patau syndrome - Patau syndrome causes serious defects to the eye, brain,…

This is a test to screen a pregnancy to determine whether a baby has an increased chance of having specific chromosome disorders. The test examines the baby's DNA in the mother's blood. Williams Syndrome Williams syndrome is a rare disorder that can lead to problems with development. It is passed down in the offsprings of families. One of the 25 missing genes is the one that produces elastin, a protein that allows blood vessels and other tissues in the body to stretch. It is likely that…

Mohammad Ekrama Biology 22 Professor Clark 1october 2016 Christianson Syndrome Abstract: Christianson Syndrome is a super rare disease, it is a recessive X-linked disorder ,that usually affects the human body, specifically the nervous system. There are a lot of symptoms for this disorder like ataxia, seizures, epilepsy, severe mental retardation and microcephaly. Mutations on the SLC9A6 gene cause Christianson Syndrome, this gene is located on the X chromosome. This disorder is usually…
