Question: What is (are) Postpartum Depression ?

Answer: Many women have the baby blues after childbirth. If you have the baby blues, you may have mood swings, feel sad, anxious or overwhelmed, have crying spells, lose your appetite, or have trouble sleeping. The baby blues most often go away within a few days or a week. The symptoms are not severe and do not need treatment.    The symptoms of postpartum depression last longer and are more severe. You may also feel hopeless and worthless, and lose interest in the baby. You may have thoughts of hurting yourself or the baby. Very rarely, new mothers develop something even more serious. They may have hallucinations or try to hurt themselves or the baby. They need to get treatment right away, often in the hospital.    Postpartum depression can begin anytime within the first year after childbirth. The cause is not known. Hormonal and physical changes after birth and the stress of caring for a new baby may play a role. Women who have had depression are at higher risk.    If you think you have postpartum depression, tell your health care provider. Medicines, including antidepressants and talk therapy can help you get well.

Question: What is (are) Acromesomelic dysplasia ?

Answer: Acromesomelic dysplasia describes a group of extremely rare, inherited, progressive skeletal conditions that result in a particular form of short stature, called short-limb dwarfism. The short stature is the result of unusually short forearms and forelegs (mesomelia) and abnormal shortening of the bones in the hands and feet (acromelia). At birth, the hands and feet may appear abnormally short and broad. Over time, the apparent disproportion becomes even more obvious, especially during the first years of life. Additional features may include: limited extension of the elbows and arms; progressive abnormal curvature of the spine; an enlarged head; and a slightly flattened midface. Acromesomelic dysplasia is inherited as an autosomal recessive trait. There are different types of acromesomelic dysplasia, which are distinguished by their genetic cause.

Question: What is (are) Cardiofaciocutaneous syndrome ?

Answer: Cardiofaciocutaneous (CFC) syndrome is a disorder that affects many parts of the body, particularly the heart (cardio-), face (facio-), and the skin and hair (cutaneous). People with this condition also have developmental delay and intellectual disability, usually ranging from moderate to severe. The signs and symptoms of cardiofaciocutaneous syndrome overlap significantly with those of two other genetic conditions, Costello syndrome and Noonan syndrome. The three syndromes are part of a group of related conditions called the RASopathies and  they are distinguished by their genetic cause and specific patterns of signs and symptoms; however, it can be difficult to tell these conditions apart in infancy. The CFC syndroeme is caused by mutations in the BRAF (75%-80% of the cases), MAP2K1,  MAP2K2 or KRAS gene (in fewer than 5% of the cases). CFC syndrome is an autosomal dominant condition, however, most cases have resulted from new gene mutations and have occurred in people with no history of the disorder in their family. Treatment is symptomatic and may include surgery to correct the heart problems.
Question: What is (are) LEOPARD syndrome ?

Answer: LEOPARD syndrome is an inherited condition characterized by abnormalities of the skin, heart, inner ears, and genitalia. The acronym LEOPARD describes the characteristic features associated with this condition: (L)entigines (multiple dark spots on the skin; (E)lectrocardiographic conduction defects (abnormalities of the electrical activity of the heart); (O)cular hypertelorism (widely spaced eyes); (P)ulmonary stenosis (obstruction of the normal outflow of blood from the right ventricle of the heart); (A)bnormalities of the genitalia; (R)etarded growth resulting in short stature; and (D)eafness or hearing loss. There are three types of LEOPARD syndrome, which are distinguished by their underlying genetic cause. LEOPARD syndrome type 1 is caused by mutations in the PTPN11 gene; type 2 is caused by mutations in the RAF1 gene; and type 3 is caused by mutations in the BRAF gene. Some cases are inherited from a parent in an autosomal dominant pattern. Other times, LEOPARD syndrome occurs in people without a family history of the condition due to a new gene mutation.
Question: Is Hypophosphatemic rickets inherited ?

Answer: How is hypophosphatemic rickets inherited? Hypophosphatemic rickets is most often inherited in an X-linked dominant manner. This means that the gene responsible for the condition is located on the X chromosome, and having only one mutated copy of the gene is enough to cause the condition. Because males have only one X chromosome (and one Y chromosome) and females have two X chromosomes, X-linked dominant conditions affect males and females differently. Both males and females can have an X-linked dominant condition. However, because males don't have a second, working copy of the gene (as females do), they usually have more severe disease than females. If a father has the mutated X-linked gene: all of his daughters will inherit the mutated gene (they will all receive his X chromosome) none of his sons will inherit the mutated gene (they only inherit his Y chromosome) If a mother has the mutated X-linked gene, each of her children (both male and female) has a 50% chance to inherit the mutated gene. Less commonly, hypophosphatemic rickets is inherited in an X-linked recessive, autosomal dominant, or autosomal recessive manner.
Question: What causes Common variable immunodeficiency ?

Answer: What causes common variable immunodeficiency (CVID)? Common variable immunodeficiency (CVID) is usually sporadic and thought to result from a combination of genetic and environmental factors. In most cases, the exact cause of CVID is unknown. Genetic factors associated with CVID include mutations in genes involved in the development and function of immune system cells (B cells) which help protect against infection. B cells make proteins called antibodies (also known as immunoglobulins), which attach to foreign agents and "mark" them to be destroyed. Mutations in genes associated with CVID result in B cells that don't make enough antibodies. This causes difficulty fighting infections, causing the signs and symptoms of CVID. Mutations in at least 10 genes have been associated with CVID. About 10% of affected people have mutations in the TNFRSF13B gene. However, not all people who inherit a mutation associated with CVID develop the disease. This is why additional genetic and/or environmental factors are probably needed for the disorder to occur. While CVID usually occurs in people with no family history of the condition, some cases are inherited in an autosomal dominant or autosomal recessive manner.
Question: What are the treatments for Pantothenate kinase-associated neurodegeneration ?

Answer: How might pantothenate kinase-associated neurodegeneration (PKAN) be treated? Currently there is no cure for this condition. Treatment consists of medications and surgery to relieve symptoms. For many of the treatments that do improve symptoms, the period of benefit is limited. Baclofen and trihexyphenidyl remain the most effective drugs for the dystonia and spasticity associated with this condition. Botulinum toxin may be helpful for many affected individuals, especially in treating a limited body region. For example, injections in the facial muscles can greatly improve speech and eating abilities. Those with PKAN typically do not benefit from L-dopa. Deep brain stimulation (DBS) is also an option for relieving some symptoms; an international study of the effectiveness of DBS is currently underway. Recently, interest in chelating agents (agents that remove iron from the body) has also been revived, although the benefits have not yet been documented and systemic anemia remains a risk. A trial using deferriprone (a chelator) in PKAN is currently underway in Italy. Click on the link to learn more about this study.
Question: What are the genetic changes related to tyrosine hydroxylase deficiency ?

Answer: Mutations in the TH gene cause TH deficiency. The TH gene provides instructions for making the enzyme tyrosine hydroxylase, which is important for normal functioning of the nervous system. Tyrosine hydroxylase takes part in the pathway that produces a group of chemical messengers (hormones) called catecholamines. Tyrosine hydroxylase helps convert the protein building block (amino acid) tyrosine to a catecholamine called dopamine. Dopamine transmits signals to help the brain control physical movement and emotional behavior. Other catecholamines called norepinephrine and epinephrine are produced from dopamine. Norepinephrine and epinephrine are involved in the autonomic nervous system.  Mutations in the TH gene result in reduced activity of the tyrosine hydroxylase enzyme. As a result, the body produces less dopamine, norepinephrine and epinephrine. These catecholamines are necessary for normal nervous system function, and changes in their levels contribute to the abnormal movements, autonomic dysfunction, and other neurological problems seen in people with TH deficiency.
Question: What are the genetic changes related to rapid-onset dystonia parkinsonism ?

Answer: Rapid-onset dystonia parkinsonism is caused by mutations in the ATP1A3 gene. This gene provides instructions for making one part of a larger protein called Na+/K+ ATPase, also known as the sodium pump. This protein is critical for the normal function of nerve cells (neurons) in the brain. It transports charged atoms (ions) into and out of neurons, which is an essential part of the signaling process that controls muscle movement.  Mutations in the ATP1A3 gene reduce the activity of the Na+/K+ ATPase or make the protein unstable. Studies suggest that the defective protein is unable to transport ions normally, which disrupts the electrical activity of neurons in the brain. However, it is unclear how a malfunctioning Na+/K+ ATPase causes the movement abnormalities characteristic of rapid-onset dystonia parkinsonism.  In some people with rapid-onset dystonia parkinsonism, no mutation in the ATP1A3 gene has been identified. The genetic cause of the disorder is unknown in these individuals. Researchers believe that mutations in at least one other gene, which has not been identified, can cause this disorder.
Question: What are the genetic changes related to blepharophimosis, ptosis, and epicanthus inversus syndrome ?

Answer: Mutations in the FOXL2 gene cause BPES types I and II. The FOXL2 gene provides instructions for making a protein that is active in the eyelids and ovaries. The FOXL2 protein is likely involved in the development of muscles in the eyelids. Before birth and in adulthood, the protein regulates the growth and development of certain ovarian cells and the breakdown of specific molecules.  It is difficult to predict the type of BPES that will result from the many FOXL2 gene mutations. However, mutations that result in a partial loss of FOXL2 protein function generally cause BPES type II. These mutations probably impair regulation of normal development of muscles in the eyelids, resulting in malformed eyelids that cannot open fully. Mutations that lead to a complete loss of FOXL2 protein function often cause BPES type I. These mutations impair the regulation of eyelid development as well as various activities in the ovaries, resulting in eyelid malformation and abnormally accelerated maturation of certain ovarian cells and the premature death of egg cells.
Question: Is Beckwith-Wiedemann syndrome inherited ?

Answer: In about 85 percent of cases of Beckwith-Wiedemann syndrome, only one person in a family has been diagnosed with the condition. However, parents of one child with Beckwith-Wiedemann syndrome may be at risk of having other children with the disorder. This risk depends on the genetic cause of the condition.  Another 10 to 15 percent of people with Beckwith-Wiedemann syndrome are part of families with more than one affected family member. In most of these families, the condition appears to have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means that one copy of an altered gene in each cell is typically sufficient to cause the disorder. In most of these cases, individuals with Beckwith-Wiedemann syndrome inherit the genetic change from their mothers. Occasionally, a person who inherits the altered gene will not have any of the characteristic signs and symptoms of the condition.  Rarely, Beckwith-Wiedemann syndrome results from changes in the structure of chromosome 11. Some of these chromosomal abnormalities are inherited from a parent, while others occur as random events during the formation of reproductive cells (eggs and sperm) or in the earliest stages of development before birth.
Question: What is (are) molybdenum cofactor deficiency ?

Answer: Molybdenum cofactor deficiency is a rare condition characterized by brain dysfunction (encephalopathy) that worsens over time. Babies with this condition appear normal at birth, but within a week they have difficulty feeding and develop seizures that do not improve with treatment (intractable seizures). Brain abnormalities, including deterioration (atrophy) of brain tissue, lead to severe developmental delay; affected individuals usually do not learn to sit unassisted or to speak. A small percentage of affected individuals have an exaggerated startle reaction (hyperekplexia) to unexpected stimuli such as loud noises. Other features of molybdenum cofactor deficiency can include a small head size (microcephaly) and facial features that are described as "coarse."  Tests reveal that affected individuals have high levels of chemicals called sulfite, S-sulfocysteine, xanthine, and hypoxanthine in the urine and low levels of a chemical called uric acid in the blood.  Because of the serious health problems caused by molybdenum cofactor deficiency, affected individuals usually do not survive past early childhood.
Question: What are the genetic changes related to combined malonic and methylmalonic aciduria ?

Answer: Mutations in the ACSF3 gene cause CMAMMA. This gene provides instructions for making an enzyme that plays a role in the formation (synthesis) of fatty acids. Fatty acids are building blocks used to make fats (lipids). The ACSF3 enzyme performs a chemical reaction that converts malonic acid to malonyl-CoA, which is the first step of fatty acid synthesis in cellular structures called mitochondria. Based on this activity, the enzyme is classified as a malonyl-CoA synthetase. The ACSF3 enzyme also converts methylmalonic acid to methylmalonyl-CoA, making it a methylmalonyl-CoA synthetase as well.  The effects of ACSF3 gene mutations are unknown. Researchers suspect that the mutations lead to altered enzymes that have little or no function. Because the enzyme cannot convert malonic and methylmalonic acids, they build up in the body. Damage to organs and tissues caused by accumulation of these acids may be responsible for the signs and symptoms of CMAMMA, although the mechanisms are unclear.
Question: What are the genetic changes related to autosomal dominant vitreoretinochoroidopathy ?

Answer: ADVIRC is caused by mutations in the BEST1 gene. The protein produced from this gene, called bestrophin-1, is thought to play a critical role in normal vision. Bestrophin-1 is found in a thin layer of cells at the back of the eye called the retinal pigment epithelium. This cell layer supports and nourishes the retina and is involved in growth and development of the eye, maintenance of the retina, and the normal function of specialized cells called photoreceptors that detect light and color. In the retinal pigment epithelium, bestrophin-1 functions as a channel that transports charged chlorine atoms (chloride ions) across the cell membrane.  Mutations in the BEST1 gene alter how the gene's instructions are used to make bestrophin-1, which leads to production of versions of the protein that are missing certain segments or have extra segments. It is not clear how these versions of bestrophin affect chloride ion transport or lead to the eye abnormalities characteristic of ADVIRC. Researchers suspect that the abnormalities are related to defects in the retinal pigment epithelium or the photoreceptors.
Question: What are the genetic changes related to benign essential blepharospasm ?

Answer: The causes of benign essential blepharospasm are unknown, although the disorder likely results from a combination of genetic and environmental factors. Certain genetic changes probably increase the likelihood of developing this condition, and environmental factors may trigger the signs and symptoms in people who are at risk.  Studies suggest that this condition may be related to other forms of adult-onset dystonia, including uncontrolled twisting of the neck muscles (spasmodic torticollis) and spasms of the hand and finger muscles (writer's cramp). Researchers suspect that benign essential blepharospasm and similar forms of dystonia are associated with malfunction of the basal ganglia, which are structures deep within the brain that help start and control movement.  Although genetic factors are almost certainly involved in benign essential blepharospasm, no genes have been clearly associated with the condition. Several studies have looked at the relationship between common variations (polymorphisms) in the DRD5 and TOR1A genes and the risk of developing benign essential blepharospasm. These studies have had conflicting results, with some showing an association and others finding no connection. Researchers are working to determine which genetic factors are related to this disorder.
Question: What are the symptoms of Nonalcoholic Steatohepatitis ?

Answer: NASH is usually a silent disease with few or no symptoms. Patients generally feel well in the early stages and only begin to have symptomssuch as fatigue, weight loss, and weaknessonce the disease is more advanced or cirrhosis develops. The progression of NASH can take years, even decades. The process can stop and, in some cases, reverse on its own without specific therapy. Or NASH can slowly worsen, causing scarring or fibrosis to appear and accumulate in the liver. As fibrosis worsens, cirrhosis develops; the liver becomes seriously scarred, hardened, and unable to function normally. Not every person with NASH develops cirrhosis, but once serious scarring or cirrhosis is present, few treatments can halt the progression. A person with cirrhosis experiences fluid retention, muscle wasting, bleeding from the intestines, and liver failure. Liver transplantation is the only treatment for advanced cirrhosis with liver failure, and transplantation is increasingly performed in people with NASH. NASH ranks as one of the major causes of cirrhosis in America, behind hepatitis C and alcoholic liver disease.
Question: What is (are) Smallpox ?

Answer: Smallpox is a disease caused by the Variola major virus. Some experts say that over the centuries it has killed more people than all other infectious diseases combined. Worldwide immunization stopped the spread of smallpox three decades ago. The last case was reported in 1977. Two research labs still keep small amounts of the virus. Experts fear bioterrorists could use the virus to spread disease.    Smallpox spreads very easily from person to person. Symptoms are flu-like. They include       - High fever    - Fatigue    - Headache    - Backache    - A rash with flat red sores       There is no treatment. Fluids and medicines for pain or fever can help control symptoms. Most people recover, but some can die. Those who do recover may have severe scars.    The U.S. stopped routine smallpox vaccinations in 1972. Military and other high-risk groups continue to get the vaccine. The U.S. has increased its supply of the vaccine in recent years. The vaccine makes some people sick, so doctors save it for those at highest risk of disease.     NIH: National Institute of Allergy and Infectious Diseases
Question: What is (are) Varicose Veins ?

Answer: Varicose veins are swollen, twisted veins that you can see just under the skin. They usually occur in the legs, but also can form in other parts of the body. Hemorrhoids are a type of varicose vein.    Your veins have one-way valves that help keep blood flowing toward your heart. If the valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell, which can lead to varicose veins.    Varicose veins are very common. You are more at risk if you are older, a female, obese, don't exercise or have a family history. They can also be more common in pregnancy.    Doctors often diagnose varicose veins from a physical exam. Sometimes you may need additional tests.    Exercising, losing weight, elevating your legs when resting, and not crossing them when sitting can help keep varicose veins from getting worse. Wearing loose clothing and avoiding long periods of standing can also help. If varicose veins are painful or you don't like the way they look, your doctor may recommend procedures to remove them.

Question: What is (are) Animal Diseases and Your Health ?

Answer: Animal diseases that people can catch are called zoonoses. Many diseases affecting humans can be traced to animals or animal products. You can get a disease directly from an animal, or indirectly, through the environment.    Farm animals can carry diseases. If you touch them or things they have touched, like fencing or buckets, wash your hands thoroughly. Adults should make sure children who visit farms or petting zoos wash up as well.     Though they may be cute and cuddly, wild animals may carry germs, viruses, and parasites. Deer and deer mice carry ticks that cause Lyme disease. Some wild animals may carry rabies. Enjoy wildlife from a distance.    Pets can also make you sick. Reptiles pose a particular risk. Turtles, snakes and iguanas can transmit Salmonella bacteria to their owners. You can get rabies from an infected dog or toxoplasmosis from handling kitty litter of an infected cat. The chance that your dog or cat will make you sick is small. You can reduce the risk by practicing good hygiene, keeping pet areas clean and keeping your pets' shots up-to-date.
Question: What is (are) Rheumatoid Arthritis ?

Answer: Rheumatoid arthritis (RA) is a form of arthritis that causes pain, swelling, stiffness and loss of function in your joints. It can affect any joint but is common in the wrist and fingers.    More women than men get rheumatoid arthritis. It often starts in middle age and is most common in older people. You might have the disease for only a short time, or symptoms might come and go. The severe form can last a lifetime.    Rheumatoid arthritis is different from osteoarthritis, the common arthritis that often comes with older age. RA can affect body parts besides joints, such as your eyes, mouth and lungs. RA is an autoimmune disease, which means the arthritis results from your immune system attacking your body's own tissues.    No one knows what causes rheumatoid arthritis. Genes, environment, and hormones might contribute. Treatments include medicine, lifestyle changes, and surgery. These can slow or stop joint damage and reduce pain and swelling.
