Niemann Pick Disease Essay

5. What is the prevalence and prognosis of this condition? Is it an inheritable (genetic) condition/disease? (1 point)

Pathogens are everywhere. They are in people, animals, and the environment. Pathogens come in a wide variety. The types are fungal, bacterial, viral, and other parasites. All pathogens can be dangerous, but two of them are more dangerous. These two types that more dangerous are fungal and bacterial. While both fungal and bacterial pathogens cause illness, they differ in the way they are transmitted, the way they are treated, and the diseases they cause.

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.

This disorder runs in families so it is likely if one parent has it then the

Sickle Cell Disease is an illness that affects people all across the globe. This paper will give a description of the sickness through the discussion of the causes, symptoms, and possible cures. Sickle Cell Disease (SCD) is a "group of inherited red blood cell disorders."(1) These disorders can have various afflictions, such as pain, damage and a low blood count--Sickle Cell Anemia.

Sickle cell anemia occurs when a person inherits two abnormal genes (one from each parent) that cause their red blood cells to change shape. Instead of being flexible and round, these cells are more rigid and curved in the shape of the farm tool known as a sickle - that's where the disease gets its name. The shape

Sickle cell disease is a disease that is most prevalent in people of African descent along with people of Mediterranean and Middle Eastern origin. This disease is known to affect about 70, 000 Americans and about 2 million people carry the trait (meaning that, they carry a single gene mutation).

This syndrome is not very common, because it is a rare condition. Its prevalence is not certain, but the proximate amount is 5 to 10 individuals per million newborns. Research workers appraise that there are approximately 200 to 300 individuals around the world who have this disorder. It is observed with equivalent recurrence in both males and females over all ethnic groups.

Within a year of the examination, two of the three children died. A few years later, one of the children’s parents brought a newly born sibling with the same symptoms to Tay’s clinic; leading Tay to believe whatever the disorder was, quite possibly was hereditary (Cowan 133).

The purpose of this paper is to provide the reader with an overview of this condition. A description of the condition will be provided, including: related statistics, predisposing risk factors,

If the disease is of the homozygous variety in a person it occurs in 1 in every 10,000 people. If the disease is heterozygous then in is found between 1 in every 5,000 people and 1 in every 15,000 people. It is more common in Venezuela then anywhere else, although it is discovered in about 240 people per year in the United States. A DNA marker G8 (D4S10) is closely linked to HD and has been identified as being on the # 4 chromosome and can detect Heterozygotes. (Encarta Encyclopedia) The connection between G8 and HD has not been clinically used because it’s a very serious disease. Theoretically a homozygote can be detected parentally. If a female has a child and she is tested positive for HD and has no history of it, then the father as well as the child a bound to end up with the disease. (Textbook

This is still one of the most widely used tests because researchers still do not know exactly which gene is the defective Cystic Fibrosis gene ("Cystic,” Hereditary 47). Patients are usually diagnosed by the age of two but, a few rare causes are not diagnosed until the age of eighteen ("Cystic," umm.edu 1). Since symptoms usually appear early in life patients that are not diagnosed until later in life often have more mild forms of Cystic Fibrosis (Silverstein, Silverstein, and Silverstein 1; "Cystic," umm.edu 1). Luckily today children with Cystic Fibrosis are diagnosed early, in the nineteen-forties children often died from Cystic Fibrosis before they were old enough to attend school ("About" 1). Even though testing for Cystic Fibrosis is exceedingly simple the list of complications and illnesses associated with Cystic Fibrosis is extensive.

The sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin's, Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels, less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged. This is what causes the problems of sickle cell disease.

c.ii. This disease develops at a slow pace so most people don’t notice the symptoms.

The diagnosis of the disease, its cause or causes, stage, treatment and prognosis will be sought from the pediatrician. He establishes and explains the connection between the disease and the patient's family history. He prescribes appropriate medicines and medications to alleviate the patient's symptoms. The moral principles surrounding the couple's decision concerning the disease are contributed by the ethicist. He warns against the double-effect situation in this disease condition. He emphasizes that birth defects
