Klinefelter Syndrome

     Progeria is an autosomal recessive disease, which means it is not carried on a sex chromosome. Hutchison-Gilford Progeria is caused by a mutation in Lamin A. Lamin A is a fibrous protein involved in the structure of the nuclear membrane. When there is a mutation in Lamin A it is likely the nucleus loses its normal shape and therefore its function is compromised. As of now, it is known that this is the cause of Progeria itself; however, neither doctors nor scientist can determine what this mutation has to do with the aging-like deformities of Progeria (Kugler).

Imagine your child dying a few months after they are born because of the genes you passed down to them. This is possible with many genetic diseases; one such disease can be Krabbe disease. Krabbe disease changes many aspects of a diagnosed person’s life because of the troubling and debilitating side effects. Children with Krabbe disease might not be able to complete daily activities. This can affect not only the child but also the people around them.

Originally, researchers and scientists thought a duplication in the Y chromosome was the connection between how genetics influence crime. The male karyotype would be XYY instead of XY. They have a tendency for hyper-aggressiveness and violence (Wachbroit). This unique karyotype also leads to a significant number of abortions if the fetus carries the karyotype. The other effects of this mutation are men that are taller, less intelligent, hyperactive, and are more impulsive (Wachbroit). After much research no one could relate this to how it

The patient whose chromosomes are organized on the Karyotype Worksheet #1, is a normal female as indicated by her XX sex chromosomes, with a total number of 46 chromosomes and her karyotype doesn’t exhibit any aneuploidy or structural errors.

Most people have never had the privilege to meet a child living with Smith-Lemli-Opitz Syndrome, SLOS for short. In fact, most people have never even heard of the disease. I have been able to spend time with a SLOS child and her wonderful family for the past 4 years. Audrey Bowers is a beautiful 5 year old girl who is severely impaired due to her genetic condition. SLOS is a rare metabolic disorder caused by a mutation in a gene found on chromosome 11. This specific gene corresponds to an enzyme that aids in the production of cholesterol within the body (Smith). Children with SLOS, like Audrey, are unable to produce enough cholesterol which leads to significant deficits in mental and physical development.

XYY Syndrome is a genetic disease where a male has an extra Y chromosome. This could then lead to an increased risk of learning disabilities.(Genetics Home Reference). XYY Syndrome

It is an inherited genetic disease. It is passed down in families in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show any symptoms. Around 1 person in every 150 people are thought to be carriers. There are two types of Krabbe disease the infantile and the late on-set. The infantile form, which affects 85 to 90% of people with

Purpose – The purpose of this paper is to discuss Ekbom Syndrome, also known as primary delusional parasitosis.

The specific metabolic disorder that I picked for this discussion is Krabbe Disease or globoid cell leukodystrophy. The disease destroys the protective coating of nerve cells in the brain and throughout the body causing the nerve cells to stop responding or react unpredictably. The disease is caused by a person receiving two copies of a mutated gene that results in severely curtailed production of an enzyme called galactocerebrosidase (GALC) (Krabbe disease, n.d.). This enzyme is responsible for breaking down certain substances in a cell's recycling center. Unfortunately, in Krabbe disease, not enough GALC was produced so the cells begin accumulating fats called galactolipids which normally are responsible for maintaining the protective coating

Krabbe disease is a disorder in the nervous system in which the patient becomes unable to function correctly. This enzyme deficiency impairs the growth and maintenance of myelin, the protective covering around certain nerve cells that ensures the rapid transmission of nerve impulses. A large cell of a primary germ is found clustered together in the space between the skull and the brain causing it to destroy the cells. Although, this disease generally directed at infants it may also develop in an older child or adult.

Adrenoleukodystrophy is a genetic disease that is passed on from mother to son. ALD is an X-linked disorder. That means it affects only males and is transmitted by a female carrier. This disorder is called X-linked since the genetic abnormality involves the X-chromosome. Women have two X-chromosomes while men only have one. In women, the affected X-chromosome, the one with the gene for ALD does not become active because of the presence of a normal copy of the gene on the other X-chromosome. Men have one X-chromosome and one Y-chromosome. In men who have an X- chromosome for X-ALD, there is no other X- chromosome for protection.

Turner Syndrome is caused by a missing or incomplete X chromosome. People who have Turner Syndrome develop as females. Some of the genes on the X chromosome are involved in the growth of your height and sexual development, which is why girls with this disorder are shorter than normal and have incompletely developed sexual characteristics. Within this disorder there can be many symptoms, for example: swelling hands and feet, heart defeat, pregnancy chorionic villus sampling or amniocentesis. There are also major causes contributing to this disorder including a stocky build, arms that turn out slightly at the elbow, receding low jaw, a short webbed neck and low hair line on the back of the neck. Also includes backtracked puberty, ovaries undeveloped properly and effects sexual development.

Men with this condition have longer legs, a higher voice, and a thinner beard than average men do. Their testicles are smaller than usual and do not produce functioning sperm cells, so the men are infertile. Compared with other men, they have lower levels of androgens (male hormones) and more estrogens (female hormones). For this reason, they often develop gynecomastia (benign male breast growth) and have an increased risk of male breast cancer.

The XXY syndrome, most commonly known as Klinefelter syndrome (KS), only affects males of all ages. This syndrome occurs when there is a random genetic error after conception and is not curable, however treatment can help.All females have XX chromosome and all males have XY chromosomes. Unlike the normal XY type that all males have, males affected have an additional X chromosome which results into many symptoms such as impaired spermatogenesis, low testosterone, and male hypogonadism. Since Klinefelter syndrome is related to the sex chromosomes of males, it is a sex link trait.
