Topic: systemic lupus erythematosus
Question: What is (are) systemic lupus erythematosus ?
Answer: Systemic lupus erythematosus (SLE) is a chronic disease that causes inflammation in connective tissues, such as cartilage and the lining of blood vessels, which provide strength and flexibility to structures throughout the body. The signs and symptoms of SLE vary among affected individuals, and can involve many organs and systems, including the skin, joints, kidneys, lungs, central nervous system, and blood-forming (hematopoietic) system. SLE is one of a large group of conditions called autoimmune disorders that occur when the immune system attacks the body's own tissues and organs.  SLE may first appear as extreme tiredness (fatigue), a vague feeling of discomfort or illness (malaise), fever, loss of appetite, and weight loss. Most affected individuals also have joint pain, typically affecting the same joints on both sides of the body, and muscle pain and weakness. Skin problems are common in SLE. A characteristic feature is a flat red rash across the cheeks and bridge of the nose, called a "butterfly rash" because of its shape. The rash, which generally does not hurt or itch, often appears or becomes more pronounced when exposed to sunlight. Other skin problems that may occur in SLE include calcium deposits under the skin (calcinosis), damaged blood vessels (vasculitis) in the skin, and tiny red spots called petechiae. Petechiae are caused by a shortage of blood clotting cells called platelets that leads to bleeding under the skin. Affected individuals may also have hair loss (alopecia) and open sores (ulcerations) in the moist lining (mucosae) of the mouth, nose, or, less commonly, the genitals.  About a third of people with SLE develop kidney disease (nephritis). Heart problems may also occur in SLE, including inflammation of the sac-like membrane around the heart (pericarditis) and abnormalities of the heart valves, which control blood flow in the heart. Heart disease caused by fatty buildup in the blood vessels (atherosclerosis), which is very common in the general population, is even more common in people with SLE. The inflammation characteristic of SLE can also damage the nervous system, and may result in abnormal sensation and weakness in the limbs (peripheral neuropathy); seizures; stroke; and difficulty processing, learning, and remembering information (cognitive impairment). Anxiety and depression are also common in SLE.  People with SLE have episodes in which the condition gets worse (exacerbations) and other times when it gets better (remissions). Overall, SLE gradually gets worse over time, and damage to the major organs of the body can be life-threatening.

Question: How many people are affected by systemic lupus erythematosus ?
Answer: For unknown reasons, in industrialized Western countries SLE has become 10 times more common over the past 50 years. While estimates of its prevalence vary, SLE is believed to affect 14.6 to 68 per 100,000 people in the United States, with females developing SLE more often than males. It is most common in younger women; however, 20 percent of SLE cases occur in people over age 50. Because many of the signs and symptoms of SLE resemble those of other disorders, diagnosis may be delayed for years, and the condition may never be diagnosed in some affected individuals.  In industrialized Western countries, people of African and Asian descent are two to four times more likely to develop SLE than are people of European descent. However, while the prevalence of SLE in Africa and Asia is unknown, it is believed to be much lower than in Western nations. Researchers suggest that factors such as ethnic mixing, tobacco use in industrialized countries, and the different types of infections people acquire in different regions may help account for the discrepancy. For example malaria, which occurs often in tropical regions, is thought to be protective against SLE, while the Epstein-Barr virus, more common in the West, increases SLE risk.

Question: What are the genetic changes related to systemic lupus erythematosus ?
Answer: Normal variations (polymorphisms) in many genes can affect the risk of developing SLE, and in most cases multiple genetic factors are thought to be involved. In rare cases, SLE is caused by mutations in single genes. Most of the genes associated with SLE are involved in immune system function, and variations in these genes likely affect proper targeting and control of the immune response. Sex hormones and a variety of environmental factors including viral infections, diet, stress, chemical exposures, and sunlight are also thought to play a role in triggering this complex disorder. About 10 percent of SLE cases are thought to be triggered by drug exposure, and more than 80 drugs that may be involved have been identified.  In people with SLE, cells that have undergone self-destruction (apoptosis) because they are damaged or no longer needed are not cleared away properly. The relationship of this loss of function to the cause or features of SLE is unclear. Researchers suggest that these dead cells may release substances that cause the immune system to react inappropriately and attack the body's tissues, resulting in the signs and symptoms of SLE.

Topic: systemic lupus erythematosus
Question: Is systemic lupus erythematosus inherited ?
Answer: SLE and other autoimmune disorders tend to run in families, but the inheritance pattern is usually unknown. People may inherit a gene variation that increases or decreases the risk of SLE, but in most cases do not inherit the condition itself. Not all people with SLE have a gene variation that increases the risk, and not all people with such a gene variation will develop the disorder.  In rare cases, SLE can be inherited 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 signs and symptoms of the condition.

Topic: ataxia with vitamin E deficiency
Question: What is (are) ataxia with vitamin E deficiency ?
Answer: Ataxia with vitamin E deficiency is a disorder that impairs the body's ability to use vitamin E obtained from the diet. Vitamin E is an antioxidant, which means that it protects cells in the body from the damaging effects of unstable molecules called free radicals. A shortage (deficiency) of vitamin E can lead to neurological problems, such as difficulty coordinating movements (ataxia) and speech (dysarthria), loss of reflexes in the legs (lower limb areflexia), and a loss of sensation in the extremities (peripheral neuropathy). Some people with this condition have developed an eye disorder called retinitis pigmentosa that causes vision loss. Most people who have ataxia with vitamin E deficiency start to experience problems with movement between the ages of 5 and 15 years. The movement problems tend to worsen with age.

Topic: ataxia with vitamin E deficiency
Question: What are the genetic changes related to ataxia with vitamin E deficiency ?
Answer: Mutations in the TTPA gene cause ataxia with vitamin E deficiency. The TTPA gene provides instructions for making the -tocopherol transfer protein (TTP), which is found in the liver and brain. This protein controls distribution of vitamin E obtained from the diet (also called -tocopherol) to cells and tissues throughout the body. Vitamin E helps cells prevent damage that might be done by free radicals.  TTPA gene mutations impair the activity of the TTP protein, resulting in an inability to retain and use dietary vitamin E. As a result, vitamin E levels in the blood are greatly reduced and free radicals accumulate within cells. Nerve cells (neurons) in the brain and spinal cord (central nervous system) are particularly vulnerable to the damaging effects of free radicals and these cells die off when they are deprived of vitamin E. Nerve cell damage can lead to problems with movement and other features of ataxia with vitamin E deficiency.

Topic: mucolipidosis type IV
Question: What is (are) mucolipidosis type IV ?
Answer: Mucolipidosis type IV is an inherited disorder characterized by delayed development and vision impairment that worsens over time. The severe form of the disorder is called typical mucolipidosis type IV, and the mild form is called atypical mucolipidosis type IV.  Approximately 95 percent of individuals with this condition have the severe form. People with typical mucolipidosis type IV have delayed development of mental and motor skills (psychomotor delay). Motor skills include sitting, standing, walking, grasping objects, and writing. Psychomotor delay is moderate to severe and usually becomes apparent during the first year of life. Affected individuals have intellectual disability, limited or absent speech, difficulty chewing and swallowing, weak muscle tone (hypotonia) that gradually turns into abnormal muscle stiffness (spasticity), and problems controlling hand movements. Most people with typical mucolipidosis type IV are unable to walk independently. In about 15 percent of affected individuals, the psychomotor problems worsen over time.  Vision may be normal at birth in people with typical mucolipidosis type IV, but it becomes increasingly impaired during the first decade of life. Individuals with this condition develop clouding of the clear covering of the eye (cornea) and progressive breakdown of the light-sensitive layer at the back of the eye (retina). By their early teens, affected individuals have severe vision loss or blindness.  People with typical mucolipidosis type IV also have impaired production of stomach acid (achlorhydria). Achlorhydria does not cause any symptoms in these individuals, but it does result in unusually high levels of gastrin in the blood. Gastrin is a hormone that regulates the production of stomach acid. Individuals with mucolipidosis type IV may not have enough iron in their blood, which can lead to a shortage of red blood cells (anemia). People with the severe form of this disorder usually survive to adulthood; however, they may have a shortened lifespan.  About 5 percent of affected individuals have atypical mucolipidosis type IV. These individuals usually have mild psychomotor delay and may develop the ability to walk. People with atypical mucolipidosis type IV tend to have milder eye abnormalities than those with the severe form of the disorder. Achlorhydria also may be present in mildly affected individuals.

Topic: mucolipidosis type IV
Question: What are the genetic changes related to mucolipidosis type IV ?
Answer: Mutations in the MCOLN1 gene cause mucolipidosis type IV. This gene provides instructions for making a protein called mucolipin-1. This protein is located in the membranes of lysosomes and endosomes, compartments within the cell that digest and recycle materials. While its function is not completely understood, mucolipin-1 plays a role in the transport (trafficking) of fats (lipids) and proteins between lysosomes and endosomes. Mucolipin-1 appears to be important for the development and maintenance of the brain and retina. In addition, this protein is likely critical for normal functioning of the cells in the stomach that produce digestive acids.  Most mutations in the MCOLN1 gene result in the production of a nonfunctional protein or prevent any protein from being produced. A lack of functional mucolipin-1 impairs transport of lipids and proteins, causing these substances to build up inside lysosomes. Conditions that cause molecules to accumulate inside the lysosomes, including mucolipidosis type IV, are called lysosomal storage disorders. Two mutations in the MCOLN1 gene account for almost all cases of mucolipidosis type IV in people with Ashkenazi Jewish ancestry. It remains unclear how mutations in this gene lead to the signs and symptoms of mucolipidosis type IV.

Topic: Wagner syndrome
Question: What is (are) Wagner syndrome ?
Answer: Wagner syndrome is a hereditary disorder that causes progressive vision loss. The eye problems that lead to vision loss typically begin in childhood, although the vision impairment might not be immediately apparent.  In people with Wagner syndrome, the light-sensitive tissue that lines the back of the eye (the retina) becomes thin and may separate from the back of the eye (retinal detachment). The blood vessels within the retina (known as the choroid) may also be abnormal. The retina and the choroid progressively break down (degenerate). Some people with Wagner syndrome have blurred vision because of ectopic fovea, an abnormality in which the part of the retina responsible for sharp central vision is out of place. Additionally, the thick, clear gel that fills the eyeball (the vitreous) becomes watery and thin. People with Wagner syndrome develop a clouding of the lens of the eye (cataract). Affected individuals may also experience nearsightedness (myopia), progressive night blindness, or a narrowing of their field of vision.  Vision impairment in people with Wagner syndrome can vary from near normal vision to complete loss of vision in both eyes.

Topic: Wagner syndrome
Question: What are the genetic changes related to Wagner syndrome ?
Answer: Mutations in the VCAN gene cause Wagner syndrome. The VCAN gene provides instructions for making a protein called versican. Versican is found in the extracellular matrix, which is the intricate lattice of proteins and other molecules that forms in the spaces between cells. Versican interacts with many of these proteins and molecules to facilitate the assembly of the extracellular matrix and ensure its stability. Within the eye, versican interacts with other proteins to maintain the structure and gel-like consistency of the vitreous.  VCAN gene mutations that cause Wagner syndrome lead to insufficient levels of versican in the vitreous. Without enough versican to interact with the many proteins of the vitreous, the structure becomes unstable. This lack of stability in the vitreous affects other areas of the eye and contributes to the vision problems that occur in people with Wagner syndrome. It is unknown why VCAN gene mutations seem solely to affect vision.

Topic: facioscapulohumeral muscular dystrophy
Question: What is (are) facioscapulohumeral muscular dystrophy ?
Answer: Facioscapulohumeral muscular dystrophy is a disorder characterized by muscle weakness and wasting (atrophy). This condition gets its name from the muscles that are affected most often: those of the face (facio-), around the shoulder blades (scapulo-), and in the upper arms (humeral). The signs and symptoms of facioscapulohumeral muscular dystrophy usually appear in adolescence. However, the onset and severity of the condition varies widely. Milder cases may not become noticeable until later in life, whereas rare severe cases become apparent in infancy or early childhood.  Weakness involving the facial muscles or shoulders is usually the first symptom of this condition. Facial muscle weakness often makes it difficult to drink from a straw, whistle, or turn up the corners of the mouth when smiling. Weakness in muscles around the eyes can prevent the eyes from closing fully while a person is asleep, which can lead to dry eyes and other eye problems. For reasons that are unclear, weakness may be more severe in one side of the face than the other. Weak shoulder muscles tend to make the shoulder blades (scapulae) protrude from the back, a common sign known as scapular winging. Weakness in muscles of the shoulders and upper arms can make it difficult to raise the arms over the head or throw a ball.  The muscle weakness associated with facioscapulohumeral muscular dystrophy worsens slowly over decades and may spread to other parts of the body. Weakness in muscles of the lower legs can lead to a condition called foot drop, which affects walking and increases the risk of falls. Muscular weakness in the hips and pelvis can make it difficult to climb stairs or walk long distances. Additionally, affected individuals may have an exaggerated curvature of the lower back (lordosis) due to weak abdominal muscles. About 20 percent of affected individuals eventually require the use of a wheelchair.  Additional signs and symptoms of facioscapulohumeral muscular dystrophy can include mild high-tone hearing loss and abnormalities involving the light-sensitive tissue at the back of the eye (the retina). These signs are often not noticeable and may be discovered only during medical testing. Rarely, facioscapulohumeral muscular dystrophy affects the heart (cardiac) muscle or muscles needed for breathing.  Researchers have described two types of facioscapulohumeral muscular dystrophy: type 1 (FSHD1) and type 2 (FSHD2). The two types have the same signs and symptoms and are distinguished by their genetic cause.

Topic: facioscapulohumeral muscular dystrophy
Question: Is facioscapulohumeral muscular dystrophy inherited ?
Answer: FSHD1 is inherited in an autosomal dominant pattern, which means one copy of the shortened D4Z4 region on a "permissive" chromosome 4 is sufficient to cause the disorder. In most cases, an affected person inherits the altered chromosome from one affected parent. Other people with FSHD1 have no history of the disorder in their family. These cases are described as sporadic and are caused by a new (de novo) D4Z4 contraction on one copy of a "permissive" chromosome 4.  FSHD2 is inherited in a digenic pattern, which means that two independent genetic changes are necessary to cause the disorder. To have FSHD2, an individual must inherit a mutation in the SMCHD1 gene (which is located on chromosome 18) and, separately, they must inherit one copy of a "permissive" chromosome 4. Affected individuals typically inherit the SMCHD1 gene mutation from one parent and the "permissive" chromosome 4 from the other parent. (Because neither parent has both genetic changes in most cases, they are typically unaffected.)
