Typically by age six months of age the patient experiences an enlarged liver and spleen, vomitting, and difficulity in feeding. Some children with npa have a “cherry-red spot” in the retina of the eye (this is common in tay-sachs). no prescription buy viagra Death from npa occurs between 2-4 years of age. The estimate is one out of 75 ashkenazi hews are carriers of niemann-pick type a. Other symptoms: motor-skill and coordination issues spasticity (progressive) potential of jaundice at birth with liver failure a cherry red spot in the eye (determined by an eyeâ specialist distended abdomen (liver and spleen) averaged age of death by age 2-3 rapid neurological decline cause: as a whole niemann-pick disease (a, b, c) is an inherited in a autosomal recessive manner. Both parents carry a mutated gene with a 1 and 4 chance (25%) with each pregnancy to have an affected child. cheap viagra canada Biochemcially, niemann-pick type a disease is the deciciency of an enzyme called sphingomyelinase (asm). Asm normally degrades a fatty substance better known as sphingomyelin. The defectiveness of the enzyme leads to the accumulation of sphingomyelin in the liver and spleen (primarily), brain, and lymph nodes. Npa has little to no asm production. cheap generic viagra Treatment, diagnosis, and screening currently there is no treatment for niemann-pick type a disease (npa). Approximately 1,200 type a & b cases have been diagnosed world wide. It is reported that a majority of cases reported are from ashkenazi jewish descent. Diagnosis for npa can be acheived by testing blood by measuring the asm activity in the white blood cells. Discovery of niemann-pick disease gene the discovery of the gene responsible for niemann-pick disease came to light in 1997. This discovery will help propel research on future potential effective treatments. Gene therapy has shown usefulness in mice that have npa. Niemann-pick type b niemann-pick type b (npb) is similar to niemann-pick type a. â both are also known as acid sphingomyelinase deficiency (asmd) because of the deficiency of â acid sphingomyelinase (asm).. no prescription buy viagra A patient with npb lives into late childhood or adulthood. buy softtabs viagra Patients generallyâ experienceâ little to noâ neurological set backs as type a & c. â â out of all three types of niemann-pick disease (a, b, c), type b has the longest potential life span.

Ans enlarge during the pre-teen years. There is usually no brain damage. Patients usually suffer from breathing problems and die in teen years or early adulthood. The prognosis is better for type b than type a. Type c—produces extensive brain damage. The liver and spleen are moderately enlarged. cheap quality viagra Type c usually starts in childhood and leads to death in teen years or early adulthood. no prescription buy viagra Type d—similar to type c, but occurs only in people related to a family that lived in nova scotia at the start of the 1700s. Type d is now recognized as a variation of type c. Liver and spleen copyright © nucleus medical media, inc. Causes niemann-pick disease is inherited. no prescription buy viagra It is an autosomal recessive trait, which means that both parents must carry the abnormal gene for their child to inherit the disease. no prescription buy viagra The exact cause depends on the type of niemann-pick disease. Types a and b a fatty material called sphingomyelin builds up in the patient's organs. generic low price viagra This substance is normally present in the membrane of most cells. cheapest price on viagra The enzyme acid sphingomyelinase normally breaks down this substance. However, people with type a or b either do not have enough of this enzyme or this enzyme does not work properly. Without the properly functioning enzyme, this fatty material builds up in the cells. The cells die and the organ does not work properly. Types c and d in these two types, nerve cells in the brain are unable to move cholesterol out. This allows cholesterol to build up, which keeps cells from functioning normally. Risk factors a risk factor is something that increases your chance of getting a disease or condition. Risk factors for niemann-pick disease include: family members with niemann-pick disease ashkenazi jewish heritage (types a and b) nova scotia, french-canadian ancestry (type d) spanish-american population of southern new mexico.
