Question: What are the genetic changes related to Schimke immuno-osseous dysplasia ?

Answer: Mutations in the SMARCAL1 gene increase the risk of Schimke immuno-osseous dysplasia. The SMARCAL1 gene provides instructions for producing a protein whose specific function is unknown. The SMARCAL1 protein can attach (bind) to chromatin, which is the complex of DNA and protein that packages DNA into chromosomes. Based on the function of similar proteins, SMARCAL1 is thought to influence the activity (expression) of other genes through a process known as chromatin remodeling. The structure of chromatin can be changed (remodeled) to alter how tightly DNA is packaged. Chromatin remodeling is one way gene expression is regulated during development. When DNA is tightly packed, gene expression is lower than when DNA is loosely packed.  Mutations in the SMARCAL1 gene are thought to lead to disease by affecting protein activity, protein stability, or the protein's ability to bind to chromatin. It is not clear if mutations in the SMARCAL1 gene interfere with chromatin remodeling and the expression of other genes.  The mutations associated with Schimke immuno-osseous dysplasia disrupt the usual functions of the SMARCAL1 protein or prevent the production of any functional protein. People who have mutations that cause a complete lack of functional protein tend to have a more severe form of this disorder than those who have mutations that lead to an active but malfunctioning protein. However, in order for people with SMARCAL1 gene mutations to develop Schimke immuno-osseous dysplasia, other currently unknown genetic or environmental factors must also be present.  Approximately half of all people with Schimke immuno-osseous dysplasia do not have identified mutations in the SMARCAL1 gene. In these cases, the cause of the disease is unknown.
Question: What is (are) hypercholesterolemia ?

Answer: Hypercholesterolemia is a condition characterized by very high levels of cholesterol in the blood. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals (particularly egg yolks, meat, poultry, fish, and dairy products). The body needs this substance to build cell membranes, make certain hormones, and produce compounds that aid in fat digestion. Too much cholesterol, however, increases a person's risk of developing heart disease.  People with hypercholesterolemia have a high risk of developing a form of heart disease called coronary artery disease. This condition occurs when excess cholesterol in the bloodstream is deposited in the walls of blood vessels, particularly in the arteries that supply blood to the heart (coronary arteries). The abnormal buildup of cholesterol forms clumps (plaque) that narrow and harden artery walls. As the clumps get bigger, they can clog the arteries and restrict the flow of blood to the heart. The buildup of plaque in coronary arteries causes a form of chest pain called angina and greatly increases a person's risk of having a heart attack.  Inherited forms of hypercholesterolemia can also cause health problems related to the buildup of excess cholesterol in other tissues. If cholesterol accumulates in tendons, it causes characteristic growths called tendon xanthomas. These growths most often affect the Achilles tendons and tendons in the hands and fingers. Yellowish cholesterol deposits under the skin of the eyelids are known as xanthelasmata. Cholesterol can also accumulate at the edges of the clear, front surface of the eye (the cornea), leading to a gray-colored ring called an arcus cornealis.
Question: What is (are) Diabetic Neuropathies: The Nerve Damage of Diabetes ?

Answer: Diabetic neuropathy can be classified as peripheral, autonomic, proximal, or focal. Each affects different parts of the body in various ways.
                
- Peripheral neuropathy, the most common type of diabetic neuropathy, causes pain or loss of feeling in the toes, feet, legs, hands, and arms.  - Autonomic neuropathy causes changes in digestion, bowel and bladder function, sexual response, and perspiration. It can also affect the nerves that serve the heart and control blood pressure, as well as nerves in the lungs and eyes. Autonomic neuropathy can also cause hypoglycemia unawareness, a condition in which people no longer experience the warning symptoms of low blood glucose levels.  - Proximal neuropathy causes pain in the thighs, hips, or buttocks and leads to weakness in the legs.  - Focal neuropathy results in the sudden weakness of one nerve or a group of nerves, causing muscle weakness or pain. Any nerve in the body can be affected.

Question: What causes Restless Legs Syndrome ?

Answer: Faulty Use of Iron or Lack of Iron
                
Research suggests that the main cause of restless legs syndrome (RLS) is a faulty use of iron or a lack of iron in the brain. The brain uses iron to make the chemical dopamine (DO-pah-meen) and to control other brain activities. Dopamine works in the parts of the brain that control movement.
                
Many conditions can affect how much iron is in the brain or how it's used. These conditions include kidney failure, Parkinson's disease, diabetes, rheumatoid arthritis, pregnancy, and iron deficiency. All of these conditions increase your risk of RLS.
                
People whose family members have RLS also are more likely to develop the disorder. This suggests that genetics may contribute to the faulty use of iron or lack of iron in the brain that triggers RLS.
                
Nerve Damage
                
Nerve damage in the legs or feet and sometimes in the arms or hands may cause or worsen RLS. Several conditions can cause this type of nerve damage, including diabetes.
                
Medicines and Substances
                
Certain medicines may trigger RLS. These include some:
                
Antinausea medicines (used to treat upset stomach)
                
Antidepressants (used to treat depression)
                
Antipsychotics (used to treat certain mental health disorders)
                
Cold and allergy medicines that contain antihistamines
                
Calcium channel blockers (used to treat heart problems and high blood pressure)
                
RLS symptoms usually get better or may even go away if the medicine is stopped.
                
Certain substances, such as alcohol and tobacco, also can trigger or worsen RLS symptoms. Symptoms may get better or go away if the substances are stopped.
Question: What is (are) spondyloepimetaphyseal dysplasia, Strudwick type ?

Answer: Spondyloepimetaphyseal dysplasia, Strudwick type is an inherited disorder of bone growth that results in short stature (dwarfism), skeletal abnormalities, and problems with vision. This condition affects the bones of the spine (spondylo-) and two regions (epiphyses and metaphyses) near the ends of long bones in the arms and legs. The Strudwick type was named after the first reported patient with the disorder.  People with this condition have short stature from birth, with a very short trunk and shortened limbs. Their hands and feet, however, are usually average-sized. Affected individuals may have an abnormally curved lower back (lordosis) or a spine that curves to the side (scoliosis). This abnormal spinal curvature may be severe and can cause problems with breathing. Instability of the spinal bones (vertebrae) in the neck may increase the risk of spinal cord damage. Other skeletal features include flattened vertebrae (platyspondyly), severe protrusion of the breastbone (pectus carinatum), an abnormality of the hip joint that causes the upper leg bones to turn inward (coxa vara), and an inward- and upward-turning foot (clubfoot). Arthritis may develop early in life.  People with spondyloepimetaphyseal dysplasia, Strudwick type have mild changes in their facial features. Some infants are born with an opening in the roof of the mouth (a cleft palate) and their cheekbones may appear flattened. Eye problems that can impair vision are common, such as severe nearsightedness (high myopia) and tearing of the lining of the eye (retinal detachment).
Question: What is (are) congenital insensitivity to pain with anhidrosis ?

Answer: Congenital insensitivity to pain with anhidrosis (CIPA) has two characteristic features: the inability to feel pain and temperature, and decreased or absent sweating (anhidrosis). This condition is also known as hereditary sensory and autonomic neuropathy type IV. The signs and symptoms of CIPA appear early, usually at birth or during infancy, but with careful medical attention, affected individuals can live into adulthood.  An inability to feel pain and temperature often leads to repeated severe injuries. Unintentional self-injury is common in people with CIPA, typically by biting the tongue, lips, or fingers, which may lead to spontaneous amputation of the affected area. In addition, people with CIPA heal slowly from skin and bone injuries. Repeated trauma can lead to chronic bone infections (osteomyelitis) or a condition called Charcot joints, in which the bones and tissue surrounding joints are destroyed.  Normally, sweating helps cool the body temperature. However, in people with CIPA, anhidrosis often causes recurrent, extremely high fevers (hyperpyrexia) and seizures brought on by high temperature (febrile seizures).  In addition to the characteristic features, there are other signs and symptoms of CIPA. Many affected individuals have thick, leathery skin (lichenification) on the palms of their hands or misshapen fingernails or toenails. They can also have patches on their scalp where hair does not grow (hypotrichosis). About half of people with CIPA show signs of hyperactivity or emotional instability, and many affected individuals have intellectual disability. Some people with CIPA have weak muscle tone (hypotonia) when they are young, but muscle strength and tone become more normal as they get older.
Question: What is (are) cytochrome c oxidase deficiency ?

Answer: Cytochrome c oxidase deficiency is a genetic condition that can affect several parts of the body, including the muscles used for movement (skeletal muscles), the heart, the brain, or the liver. Signs and symptoms of cytochrome c oxidase deficiency usually begin before age 2 but can appear later in mildly affected individuals.  The severity of cytochrome c oxidase deficiency varies widely among affected individuals, even among those in the same family. People who are mildly affected tend to have muscle weakness (myopathy) and poor muscle tone (hypotonia) with no other health problems. More severely affected people have myopathy along with severe brain dysfunction (encephalomyopathy). Approximately one quarter of individuals with cytochrome c oxidase deficiency have a type of heart disease that enlarges and weakens the heart muscle (hypertrophic cardiomyopathy). Another possible feature of this condition is an enlarged liver, which may lead to liver failure. Most individuals with cytochrome c oxidase deficiency have a buildup of a chemical called lactic acid in the body (lactic acidosis), which can cause nausea and an irregular heart rate, and can be life-threatening.  Many people with cytochrome c oxidase deficiency have a specific group of features known as Leigh syndrome. The signs and symptoms of Leigh syndrome include loss of mental function, movement problems, hypertrophic cardiomyopathy, eating difficulties, and brain abnormalities. Cytochrome c oxidase deficiency is one of the many causes of Leigh syndrome.  Cytochrome c oxidase deficiency is frequently fatal in childhood, although some individuals with mild signs and symptoms survive into adolescence or adulthood.
Question: What is (are) epidermal nevus ?

Answer: An epidermal nevus (plural: nevi) is an abnormal, noncancerous (benign) patch of skin caused by an overgrowth of skin cells. Epidermal nevi are typically seen at birth or develop in early childhood. They can be flat, tan patches of skin or raised, velvety patches. As the affected individual ages, the nevus can become thicker and darker and develop a wart-like (verrucous) appearance. Often, epidermal nevi follow a pattern on the skin known as the lines of Blaschko. The lines of Blaschko, which are invisible on skin, are thought to follow the paths along which cells migrate as the skin develops before birth.  There are several types of epidermal nevi that are defined in part by the type of skin cell involved. The epidermis is the outermost layer of skin and is composed primarily of a specific cell type called a keratinocyte. One group of epidermal nevi, called keratinocytic or nonorganoid epidermal nevi, includes nevi that involve only keratinocytes. Other types of epidermal nevi involve additional types of epidermal cells, such as the cells that make up the hair follicles or the sebaceous glands (glands in the skin that produce a substance that protects the skin and hair). These nevi comprise a group called organoid epidermal nevi.  Some affected individuals have only an epidermal nevus and no other abnormalities. However, sometimes people with an epidermal nevus also have problems in other body systems, such as the brain, eyes, or bones. In these cases, the affected individual has a condition called an epidermal nevus syndrome. There are several different epidermal nevus syndromes characterized by the type of epidermal nevus involved.
