• Parkinson disease
  Parkinson disease is a progressive disorder of the central nervous system. The disorder affects several regions of the brain, including an area called the substantia nigra that controls balance and movement. Parkinson disease may also affect regions of the brain that regulate involuntary functions such as blood pressure and heart activity. Often the first symptom of Parkinson disease is trembling or shaking (tremor) of a limb, especially when the body is at rest. Typically, the tremor begins on one side of the body, usually in one hand. Tremors can also affect the arms, legs, feet, and face. Other characteristic symptoms include rigidity or stiffness of the limbs and trunk, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability). Many Parkinson disease symptoms occur when nerve cells (neurons) in the substantia nigra die or become impaired. Normally, these cells produce a chemical messenger called dopamine, which transmits signals within the brain to produce smooth physical movements. When these dopamine-producing neurons die or become impaired, communication between the brain and muscles weakens, and eventually, the brain is unable to control muscle movement. In most cases of Parkinson disease, protein deposits called Lewy bodies appear in dead or dying dopamine-producing neurons. It is unclear whether Lewy bodies play a role in killing nerve cells, or if they are part of a repair process. Generally, individuals with symptoms that begin before the age of 20 years are considered juvenile-onset cases. Individuals with an onset of the disorder before age 50 are classified as early-onset cases, and late-onset cases are those that first display symptoms after age 50.

• Pfeiffer syndrome
  Pfeiffer syndrome is a genetic disorder characterized by the premature fusion of certain bones of the skull (craniosynostosis), which prevents further growth of the skull and affects the shape of the head and face. In addition, the thumbs and big toes are broader and often shorter than normal. Many of the characteristic facial features of Pfeiffer syndrome result from the premature fusion of the skull bones. The head is unable to grow normally, which leads to bulging and wide-set eyes, an underdeveloped upper jaw, and a beaked nose. About 50 percent of children with Pfeiffer syndrome have hearing loss, and dental problems are also common. Additionally, the thumbs and big toes are broader than normal and bend away from the other digits. Unusually short fingers and toes (brachydactyly) are also common, and there may be some webbing or fusion between the digits (syndactyly). Pfeiffer syndrome is divided into three subtypes. Type 1 or "classic" Pfeiffer syndrome has symptoms as described above. Most individuals with type 1 have normal intelligence and a normal life span. Types 2 and 3 are more severe forms of Pfeiffer syndrome, often involving problems with the nervous system. Type 2 is distinguished from type 3 by more extensive fusion of bones in the skull, leading to a "cloverleaf" shaped head.

• Polycystic kidney disease
  Polycystic kidney disease is a hereditary disorder that affects the kidneys and other organs. Clusters of fluid-filled sacs, called cysts, develop in the kidneys and interfere with their ability to filter waste products from the blood. The growth of cysts causes the kidneys to become enlarged and can lead to kidney failure. Cysts may also develop in other organs, particularly the liver. Frequent complications of polycystic kidney disease include dangerously high blood pressure (hypertension), pain in the back or sides, blood in the urine (hematuria), recurrent urinary tract infections, kidney stones, and heart valve abnormalities. Additionally, people with polycystic kidney disease have an increased risk of an abnormal bulging (called an aneurysm) in a large blood vessel called the aorta or in blood vessels in the brain. Aneurysms can be life-threatening if they tear or rupture. The two major forms of polycystic kidney disease are distinguished by their patterns of inheritance. The autosomal dominant form (sometimes called ADPKD) has signs and symptoms that typically begin in adulthood, although cysts in the kidney are often present from childhood. Autosomal dominant polycystic kidney disease can be further divided into type 1 and type 2, depending on which gene is mutated. The autosomal recessive form of polycystic kidney disease (sometimes called ARPKD) is much rarer and is often lethal. The signs and symptoms of the condition are usually apparent at birth or in early infancy.

• Porphyria
  Porphyria is a group of at least eight diseases caused by abnormalities in the chemical steps that lead to heme production. Found mostly in the blood, bone marrow, and liver, heme is a vital molecule for all of the body's organs. Heme is a component of hemoglobin, the molecule that carries oxygen in the blood. Genetic changes are related to the following types of porphyria. acute intermittent porphyria ALAD deficiency porphyria congenital erythropoietic porphyria erythropoietic protoporphyria hepatoerythropoietic porphyria hereditary coproporphyria porphyria cutanea tarda variegate porphyria The signs and symptoms of porphyria vary among types. Some types of porphyria (called cutaneous porphyrias) cause the skin to become overly sensitive to sunlight. Areas that are exposed to the sun develop redness, blistering, and often scarring. The clinical features of other types of porphyria (called acute porphyrias) affect the nervous system. Appearing quickly and lasting from days to weeks, these signs and symptoms include chest and abdominal pain, emotional and mental disorders, seizures, and muscle weakness. Some porphyrias have a combination of acute symptoms and symptoms that affect the skin. Environmental factors can strongly influence the occurrence and severity of signs and symptoms in some types of porphyria. Alcohol, smoking, certain drugs, hormones, exposure to sunlight, stress, and dieting or fasting can all trigger the signs and symptoms of the disorder.
• Porphyria cutanea tarda
  Porphyria cutanea tarda is the most common type of porphyria. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs. It is a component of hemoglobin, the molecule that carries oxygen in the blood. Porphyria cutanea tarda is a subtype of porphyria. When signs and symptoms occur, they usually begin in adulthood and result from the skin becoming overly sensitive to sunlight. Areas of skin exposed to the sun develop severe blistering, scarring, changes in pigmentation, and increased hair growth. Exposed skin becomes fragile and is easily damaged. People with porphyria cutanea tarda also have increased iron levels in the liver. They face a higher risk of developing abnormal liver function and liver cancer. The signs and symptoms of this condition are triggered by nongenetic factors such as alcohol abuse, excess iron, certain hormones, and viral infections.
• Porphyrins

• Primary hyperoxaluria
  Primary hyperoxaluria is a rare condition characterized by the overproduction of a substance called oxalate (or oxalic acid). In the kidneys, the excess oxalate combines with calcium to form calcium oxalate, a hard compound that is the main component of kidney stones. Deposits of calcium oxalate can lead to kidney damage, kidney failure, and injury to other organs. Primary hyperoxaluria is caused by the shortage (deficiency) of an enzyme that normally prevents the buildup of oxalate. There are two types of primary hyperoxaluria, distinguished by the enzyme that is deficient. People with type 1 primary hyperoxaluria have a shortage of a liver enzyme called alanine-glyoxylate aminotransferase (AGXT). Type 2 primary hyperoxaluria is characterized by a shortage of an enzyme called glyoxylate reductase/hydroxypyruvate reductase (GRHPR).

• Pseudoxanthoma elasticum
  Pseudoxanthoma elasticum is a progressive disorder that affects connective tissue, the material that supports and holds together different structures of the body. This condition is characterized by accumulated deposits of calcium (calcification) and other minerals in elastic fibers, a component of connective tissue. Calcification can affect elastic fibers in the skin, eyes, and blood vessels, and less frequently in other areas such as the digestive tract. As a result, people with pseudoxanthoma elasticum may have yellowish bumps (papules) on their necks, underarms, and elsewhere on the skin. They may also have changes in the eye called angioid streaks that can lead to vision loss if bleeding occurs. People with pseudoxanthoma elasticum are also at increased risk for problems involving blood vessels, such as decreased blood flow to the arms and legs, which may cause cramping or pain with exercise (claudication). Bleeding in the digestive tract is another risk. Most affected individuals live a normal lifespan.
