The Genetic Conditions of the Waardenburg Syndrome Essay

Progeria is one of the least known genetic disorders. There are two types of Progeria, the only difference being the age group that it affects. The Hutchinson-Gilford Progeria Syndrome is commonly called Childhood Progeria. The second type of Progeria is Werner’s Syndrome, which is the adult form of Progeria. What basically happens in this disorder is that age is accelerated seven times faster than that of a normal person. For example, for Hutchinson-Gilford Progeria Syndrome, a child could look like he is fifty when he is actually five years old. A twenty year old with Werner’s Syndrome could look similar to a sixty or seventy year old person. There is, even now, not much information known about this genetic disorder because

This syndrome is tested at birth with fluorescent in situ hybridization or FISH. With blood samples, they test the blood for the deletion of chromosome 7. FISH checks if many as of 22-26 genes are deleted. Because there is no cure for this syndrome, you will most likely have physical therapy and early education to help early development symptoms like speech delays and heart problems. This syndrome is not caused by environmental factors, it is completely genetic and NOT the parents fault.

Autosomal recessive inheritance is the third type known to cause muscular dystrophy, whereas both parents are carriers of the defective gene. For this reason the offspring have a 25% chance of being affected with both malformed genes, resulting in them being affected. The chance increases with cousin marriages.

This syndrome is from a mutation of a gene on chromosome 15 and this causes problems in the production of fibrillin-1 which is a protein that is an important part of connective tissue. The name for the gene is FBN1. Basically, it is the “glue” that helps to support the tissues in the human body. A child born to a parent with this syndrome has a 50% of having it. However, in the remaining 25%, neither parent has the disease which gives them a 1 in 10,000 chance of having a child with this disorder. When a child of two unaffected parents is born with it then the genetic mutation occurs in either the egg or sperm cell at the time of conception.

This happens when an affected parent has one recessive gene and one dominant gene whereas the other has two recessive genes, which allows two children to get two recessive genes meaning they will not be affected. Whereas the other two have one dominant gene meaning they will be affected by the disease.

The P1 cross was between four wmf females and nine wild-type males. The F1 progeny consisted of 12 wild-type females, and four triple-mutant males. The P2 cross resulted in 13 females, and 3 males, all with the wild-type phenotype (Table 1). The two parental crosses identify that the mutations are X-link recessive. The triple-mutant females of the P1 cross produce mutant male offspring, but wild-type females. The F1 females would be heterozygous for the mutations, but don’t express the mutations because they still have a wild-type X chromosome. However, the F1 males only have one X chromosome that comes from a mutant mother. The offspring for P1 were crossed again to make and F1 cross. The F1 cross would be X+/Y and X+/X. The F1 cross resulted in 100 F2 progenies over the course of 7 days.

The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Schindler disease type III is intermediate in severity between types I and II. Affected individuals

This syndrome is inherited in families in an autosomal dominant manner. Since Marfan syndrome is autosomal dominant, people with this disorder can be either homozygous dominant or heterozygous. This means that people carrying even one copy of the altered gene will have the disorder. Mutations of the FBN1 gene has been linked to the Marfan syndrome, although not everyone who has this mutation develops the disorder.

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

AS is caused by a deletion or mutation on the maternal chromosome 15, alteration in UBE3A gene, paternal uniparental disomy, translocation, or mutation in the gene that activates UBE3A gene. PWS is a deletion or mutation on the paternal chromosome 15, uniparental disomy, or translocation. The loss of the SNORD116 gene on chromosome

From just a simple ova to a new born baby the journey to get there isn't always short and simple . They will evolve to one the most complex organisms on the planet. Although some have a successful journey, some undergo wrong turns. Some processes are disrupted. They create disorders and many are formed the first weeks of growth.

Autosomal dominant patterns is one way that a disorder can be passed down through members of the families, which essentially means that if one inherits the abnormal gene from one parent, then there is a greater chance that you are capable of obtaining this disease. Though the recessive and dominant disorder may both be caused by mutations in the genetic code on the X chromosomes, there’s a difference between both disorders. In the recessive disorder, females in particular are mostly likely to cause the disorder itself, because females contains mutations in one of the two copies of the genes in each cell. While the males would have to have a mutation within only one copy of the gene in each cell to sufficiently cause the disorder. However in the dominant disorder females would have to obtain a mutation that would have to be exposed in both copies of the gene to cause the disorder. While the males that has one altered copy of the gene in each cell can also cause the

Hutchinson-Gilford progeria syndrome is a very rare genetic disorder that causes the affected individuals to appear older than what they are. Individuals are able to be affected by this disorder as earlier as a their first few months of life. There have been reported cases of infection seen in the fetus. Characteristics of progeria include limited growth such as short stature and low body weight, full body hair loss, and facial features that resemble an aged person. This genetic disorder can lead to other health complications such as degeneration of bone mass and tissue, scleroderma, kidney failure, loss of eye sight, atherosclerosis, and severe cardiovascular problems. There is a genetic test to diagnosis the disorder at a younger age called HGPS. Currently, there is no cure or treatment for the disease. However, patients can undergo certain surgeries such as

As Elora progresses and continues to grow, her health must be constantly monitored. She should frequently visit an eye care professional, to ensure she does not develop other eye conditions. Visiting a healthcare professional, such as a pediatrician, will also be crucial to helping Elora maintain good health as children who suffer from aniridia can also go on to develop WAGR syndrome. WAGR syndrome is an acronym for a network of diseases that commonly occur together, this network includes Aniridia and a rare kidney cancer called Will’s tumor. Elora will have to adjust to living with her disorder as she
