 What is (are) Perry syndrome ? 
 Perry syndrome is a progressive brain disease that is characterized by four major features: a pattern of movement abnormalities known as parkinsonism, psychiatric changes, weight loss, and abnormally slow breathing (hypoventilation). These signs and symptoms typically appear in a person's forties or fifties.  Parkinsonism and psychiatric changes are usually the earliest features of Perry syndrome. Signs of parkinsonism include unusually slow movements (bradykinesia), stiffness, and tremors. These movement abnormalities are often accompanied by changes in personality and behavior. The most frequent psychiatric changes that occur in people with Perry syndrome include depression, a general loss of interest and enthusiasm (apathy), withdrawal from friends and family, and suicidal thoughts. Many affected individuals also experience significant, unexplained weight loss early in the disease.  Hypoventilation is a later feature of Perry syndrome. Abnormally slow breathing most often occurs at night, causing affected individuals to wake up frequently. As the disease worsens, hypoventilation can result in a life-threatening lack of oxygen and respiratory failure.  People with Perry syndrome typically survive for about 5 years after signs and symptoms first appear. Most affected individuals ultimately die of respiratory failure or pneumonia. Suicide is another cause of death in this condition.

 Perry syndrome is very rare; about 50 affected individuals have been reported worldwide.
This is a medical question of type : genetic changes 
 What are the genetic changes related to Perry syndrome ? 
 Perry syndrome results from mutations in the DCTN1 gene. This gene provides instructions for making a protein called dynactin-1, which is involved in the transport of materials within cells. To move materials, dynactin-1 interacts with other proteins and with a track-like system of small tubes called microtubules. These components work together like a conveyer belt to move materials within cells. This transport system appears to be particularly important for the normal function and survival of nerve cells (neurons) in the brain.  Mutations in the DCTN1 gene alter the structure of dynactin-1, making it less able to attach (bind) to microtubules and transport materials within cells. This abnormality causes neurons to malfunction and ultimately die. A gradual loss of neurons in areas of the brain that regulate movement, emotion, and breathing underlies the signs and symptoms of Perry syndrome.
This is a medical question of type : inheritance 
 Is Perry syndrome inherited ? 
 This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.  In most cases, an affected person inherits the mutation from one affected parent. However, some cases result from new mutations in the gene and occur in people with no history of the disorder in their family.

 What is (are) von Hippel-Lindau syndrome ? 
 Von Hippel-Lindau syndrome is an inherited disorder characterized by the formation of tumors and fluid-filled sacs (cysts) in many different parts of the body. Tumors may be either noncancerous or cancerous and most frequently appear during young adulthood; however, the signs and symptoms of von Hippel-Lindau syndrome can occur throughout life.  Tumors called hemangioblastomas are characteristic of von Hippel-Lindau syndrome. These growths are made of newly formed blood vessels. Although they are typically noncancerous, they can cause serious or life-threatening complications. Hemangioblastomas that develop in the brain and spinal cord can cause headaches, vomiting, weakness, and a loss of muscle coordination (ataxia). Hemangioblastomas can also occur in the light-sensitive tissue that lines the back of the eye (the retina). These tumors, which are also called retinal angiomas, may cause vision loss.  People with von Hippel-Lindau syndrome commonly develop cysts in the kidneys, pancreas, and genital tract. They are also at an increased risk of developing a type of kidney cancer called clear cell renal cell carcinoma and a type of pancreatic cancer called a pancreatic neuroendocrine tumor.  Von Hippel-Lindau syndrome is associated with a type of tumor called a pheochromocytoma, which most commonly occurs in the adrenal glands (small hormone-producing glands located on top of each kidney). Pheochromocytomas are usually noncancerous. They may cause no symptoms, but in some cases they are associated with headaches, panic attacks, excess sweating, or dangerously high blood pressure that may not respond to medication. Pheochromocytomas are particularly dangerous if they develop during pregnancy.  About 10 percent of people with von Hippel-Lindau syndrome develop endolymphatic sac tumors, which are noncancerous tumors in the inner ear. These growths can cause hearing loss in one or both ears, as well as ringing in the ears (tinnitus) and problems with balance. Without treatment, these tumors can cause sudden profound deafness.

This is a medical question of type : genetic changes 
 What are the genetic changes related to von Hippel-Lindau syndrome ? 
 Mutations in the VHL gene cause von Hippel-Lindau syndrome. The VHL gene is a tumor suppressor gene, which means it keeps cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in this gene prevent production of the VHL protein or lead to the production of an abnormal version of the protein. An altered or missing VHL protein cannot effectively regulate cell survival and division. As a result, cells grow and divide uncontrollably to form the tumors and cysts that are characteristic of von Hippel-Lindau syndrome.
This is a medical question of type : inheritance 
 Is von Hippel-Lindau syndrome inherited ? 
 Mutations in the VHL gene are inherited in an autosomal dominant pattern, which means that one copy of the altered gene in each cell is sufficient to increase the risk of developing tumors and cysts. Most people with von Hippel-Lindau syndrome inherit an altered copy of the gene from an affected parent. In about 20 percent of cases, however, the altered gene is the result of a new mutation that occurred during the formation of reproductive cells (eggs or sperm) or very early in development.  Unlike most autosomal dominant conditions, in which one altered copy of a gene in each cell is sufficient to cause the disorder, two copies of the VHL gene must be altered to trigger tumor and cyst formation in von Hippel-Lindau syndrome. A mutation in the second copy of the VHL gene occurs during a person's lifetime in certain cells within organs such as the brain, retina, and kidneys. Cells with two altered copies of this gene make no functional VHL protein, which allows tumors and cysts to develop. Almost everyone who inherits one VHL mutation will eventually acquire a mutation in the second copy of the gene in some cells, leading to the features of von Hippel-Lindau syndrome.

 What is (are) cerebrotendinous xanthomatosis ? 
 Cerebrotendinous xanthomatosis is a fat (lipid) storage disorder that affects many areas of the body. People with this disorder cannot break down certain lipids effectively, specifically different forms of cholesterol, so these fats accumulate in various areas of the body. Xanthomatosis refers to the formation of fatty yellow nodules (xanthomas). Cerebrotendinous refers to the typical locations of the xanthomas (cerebro- meaning the brain and -tendinous meaning connective tissue called tendons that attach muscle to bone).  Other features of cerebrotendinous xanthomatosis include chronic diarrhea during infancy, clouding of the lens of the eye (cataracts) developing in late childhood, progressively brittle bones that are prone to fracture, and neurological problems in adulthood, such as dementia, seizures, hallucinations, depression, and difficulty with coordinating movements (ataxia) and speech (dysarthria). The neurological symptoms are thought to be caused by an accumulation of fats and an increasing number of xanthomas in the brain. Xanthomas can also accumulate in the fatty substance that insulates and protects nerves (myelin), disrupting nerve signaling in the brain. Disorders that involve the destruction of myelin are known as leukodystrophies. Degeneration (atrophy) of brain tissue caused by excess lipid deposits also contributes to the neurological problems.  Xanthomas in the tendons (most commonly in the Achilles tendon, which connects the heel of the foot to the calf muscles) begin to form in early adulthood. Tendon xanthomas may cause discomfort and interfere with tendon flexibility. People with cerebrotendinous xanthomatosis are also at an increased risk of developing cardiovascular disease. If untreated, the signs and symptoms related to the accumulation of lipids throughout the body worsen over time; however, the course of this condition varies greatly among those who are affected.

 How many people are affected by cerebrotendinous xanthomatosis ? 
 The incidence of cerebrotendinous xanthomatosis is estimated to be 3 to 5 per 100,000 people worldwide. This condition is more common in the Moroccan Jewish population with an incidence of 1 in 108 individuals.
This is a medical question of type : genetic changes 
 What are the genetic changes related to cerebrotendinous xanthomatosis ? 
 Mutations in the CYP27A1 gene cause cerebrotendinous xanthomatosis. The CYP27A1 gene provides instructions for producing an enzyme called sterol 27-hydroxylase. This enzyme works in the pathway that breaks down cholesterol to form acids used in the digestion of fats (bile acids). Mutations in sterol 27-hydroxylase impair its ability to break down cholesterol to a specific bile acid called chenodeoxycholic acid. As a result, a molecule called cholestanol, which is similar to cholesterol, accumulates in xanthomas, blood, nerve cells, and the brain. Cholesterol levels are not increased in the blood, but they are elevated in various tissues throughout the body. The accumulation of cholesterol and cholestanol in the brain, tendons, and other tissues causes the signs and symptoms of cerebrotendinous xanthomatosis.
This is a medical question of type : inheritance 
 Is cerebrotendinous xanthomatosis inherited ? 
 This condition is 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.

 What is (are) lymphedema-distichiasis syndrome ? 
 Lymphedema-distichiasis syndrome is a condition that affects the normal function of the lymphatic system, which is a part of the circulatory and immune systems. The lymphatic system produces and transports fluids and immune cells throughout the body. People with lymphedema-distichiasis syndrome develop puffiness or swelling (lymphedema) of the limbs, typically the legs and feet. Another characteristic of this syndrome is the growth of extra eyelashes (distichiasis), ranging from a few extra eyelashes to a full extra set on both the upper and lower lids. These eyelashes do not grow along the edge of the eyelid, but out of its inner lining. When the abnormal eyelashes touch the eyeball, they can cause damage to the clear covering of the eye (cornea). Related eye problems can include an irregular curvature of the cornea causing blurred vision (astigmatism) or scarring of the cornea. Other health problems associated with this disorder include swollen and knotted (varicose) veins, droopy eyelids (ptosis), heart abnormalities, and an opening in the roof of the mouth (a cleft palate).  All people with lymphedema-distichiasis syndrome have extra eyelashes present at birth. The age of onset of lymphedema varies, but it most often begins during puberty. Males usually develop lymphedema earlier than females, but all affected individuals will develop lymphedema by the time they are in their forties.
This is a medical question of type : frequency 
 How many people are affected by lymphedema-distichiasis syndrome ? 
 The prevalence of lymphedema-distichiasis syndrome is unknown. Because the extra eyelashes can be overlooked during a medical examination, researchers believe that some people with this condition may be misdiagnosed as having lymphedema only.
This is a medical question of type : genetic changes 
 What are the genetic changes related to lymphedema-distichiasis syndrome ? 
 Lymphedema-distichiasis syndrome is caused by mutations in the FOXC2 gene. The FOXC2 gene provides instructions for making a protein that plays a critical role in the formation of many organs and tissues before birth. The FOXC2 protein is a transcription factor, which means that it attaches (binds) to specific regions of DNA and helps control the activity of many other genes. Researchers believe that the FOXC2 protein has a role in a variety of developmental processes, such as the formation of veins and the development of the lungs, eyes, kidneys and urinary tract, cardiovascular system, and the transport system for immune cells (lymphatic vessels).

 What is (are) Jacobsen syndrome ? 
 Jacobsen syndrome is a condition caused by a loss of genetic material from chromosome 11. Because this deletion occurs at the end (terminus) of the long (q) arm of chromosome 11, Jacobsen syndrome is also known as 11q terminal deletion disorder.  The signs and symptoms of Jacobsen syndrome vary considerably. Most affected individuals have delayed development, including the development of speech and motor skills (such as sitting, standing, and walking). Most also have cognitive impairment and learning difficulties. Behavioral problems have been reported, including compulsive behavior (such as shredding paper), a short attention span, and easy distractibility. Many people with Jacobsen syndrome have been diagnosed with attention deficit-hyperactivity disorder (ADHD). Jacobsen syndrome is also associated with an increased likelihood of autism spectrum disorders, which are characterized by impaired communication and socialization skills.  Jacobsen syndrome is also characterized by distinctive facial features. These include small and low-set ears, widely set eyes (hypertelorism) with droopy eyelids (ptosis), skin folds covering the inner corner of the eyes (epicanthal folds), a broad nasal bridge, downturned corners of the mouth, a thin upper lip, and a small lower jaw. Affected individuals often have a large head size (macrocephaly) and a skull abnormality called trigonocephaly, which gives the forehead a pointed appearance.  More than 90 percent of people with Jacobsen syndrome have a bleeding disorder called Paris-Trousseau syndrome. This condition causes a lifelong risk of abnormal bleeding and easy bruising. Paris-Trousseau syndrome is a disorder of platelets, which are blood cell fragments that are necessary for blood clotting.  Other features of Jacobsen syndrome can include heart defects, feeding difficulties in infancy, short stature, frequent ear and sinus infections, and skeletal abnormalities. The disorder can also affect the digestive system, kidneys, and genitalia. The life expectancy of people with Jacobsen syndrome is unknown, although affected individuals have lived into adulthood.

 How many people are affected by Jacobsen syndrome ? 
 The estimated incidence of Jacobsen syndrome is 1 in 100,000 newborns. More than 200 affected individuals have been reported.
This is a medical question of type : genetic changes 
 What are the genetic changes related to Jacobsen syndrome ? 
 Jacobsen syndrome is caused by a deletion of genetic material at the end of the long (q) arm of chromosome 11. The size of the deletion varies among affected individuals, with most affected people missing 5 million to 16 million DNA building blocks (also written as 5 Mb to 16 Mb). In almost all affected people, the deletion includes the tip of chromosome 11. Larger deletions tend to cause more severe signs and symptoms than smaller deletions.  The features of Jacobsen syndrome are likely related to the loss of multiple genes on chromosome 11. Depending on its size, the deleted region can contain from about 170 to more than 340 genes. Many of these genes have not been well characterized. However, genes in this region appear to be critical for the normal development of many parts of the body, including the brain, facial features, and heart. Only a few genes have been studied as possible contributors to the specific features of Jacobsen syndrome; researchers are working to determine which additional genes may be associated with this condition.
This is a medical question of type : inheritance 
 Is Jacobsen syndrome inherited ? 
 Most cases of Jacobsen syndrome are not inherited. They result from a chromosomal deletion that occurs as a random event during the formation of reproductive cells (eggs or sperm) or in early fetal development. Affected people typically have no history of the disorder in their family, although they can pass the chromosome deletion to their children.  Between 5 and 10 percent of people with Jacobsen syndrome inherit the chromosome abnormality from an unaffected parent. In these cases, the parent carries a chromosomal rearrangement called a balanced translocation, in which a segment from chromosome 11 has traded places with a segment from another chromosome. In a balanced translocation, no genetic material is gained or lost. Balanced translocations usually do not cause any health problems; however, they can become unbalanced as they are passed to the next generation.  Children who inherit an unbalanced translocation can have a chromosomal rearrangement with some missing genetic material and some extra genetic material. Individuals with Jacobsen syndrome who inherit an unbalanced translocation are missing genetic material from the end of the long arm of chromosome 11 and have extra genetic material from another chromosome. These chromosomal changes result in the health problems characteristic of this disorder.
