What are the symptoms of Stiff person syndrome ?
What are the signs and symptoms of Stiff person syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Stiff person syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Adult onset - Agoraphobia - Anemia - Anxiety - Asymmetric limb muscle stiffness - Autoimmunity - Axial muscle stiffness - Depression - Exaggerated startle response - Fever - Frequent falls - Hyperhidrosis - Hyperreflexia - Hypertension - Lumbar hyperlordosis - Myoclonic spasms - Opisthotonus - Proximal limb muscle stiffness - Rigidity - Sporadic - Tachycardia - Vitiligo - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. + GARD + Stiff person syndrome
What causes Stiff person syndrome ?
What causes stiff person syndrome? Scientists dont yet understand what causes stiff person syndrome, but research indicates that it is the result of an abnormal autoimmune response in the brain and spinal cord. Most people with stiff person syndrome have antibodies to glutamic acid decarboxylase (GAD), a protein in some nerve cells involved in making a substance called gamma-aminobutyric acid (GABA) that helps to control muscle movement. The symptoms of stiff person syndrome may develop when the immune system mistakenly attacks the neurons that produce GAD, leading to a deficiency of this protein in the body. The exact role that deficiency of GAD plays in the development of stiff person syndrome is not fully understood. + GARD + Stiff person syndrome
Is Stiff person syndrome inherited ?
Is stiff person syndrome inherited? Genetic factors involved in causing stiff person syndrome have not been established.  While most cases appear to occur in an isolated manner, some familial cases have been reported. The fact that stiff person syndrome can occur with other autoimmune disorders suggests that genetics may play a role. + GARD + Stiff person syndrome
How to diagnose Stiff person syndrome ?
Is genetic testing available for stiff person syndrome? Genetic testing is not available for stiff person syndrome, as the underlying genetic cause (if any) has not yet been established. How is stiff person syndrome diagnosed? A diagnosis of stiff person syndrome (SPS) is typically made based on the presence of the characteristic symptoms, a detailed medical history, a thorough clinical exam, and various tests. Specific tests are used to support or confirm the diagnosis, and to rule out conditions with overlapping symptoms. These tests may include screening tests to detect antibodies against glutamic acid decarboxylase (GAD) and amphiphysin, and an electromyography (EMG) which records electrical activity in skeletal muscles. About 60% to 80% of affected people have autoantibodies against GAD. Although the absence of GAD antibodies does not rule out SPS, the presence of high levels of GAD antibodies in appropriate people strongly supports the diagnosis. An EMG typically shows continuous motor activity, which is characteristic of SPS. Very high levels of GAD antibodies and characteristic EMG findings will confirm the diagnosis in the majority of people with SPS. Additional laboratory testing may also be used to support a diagnosis of SPS, such as hemoglobin A1C (due to association with diabetes mellitus); complete blood count (due to association with pernicious anemia); comprehensive metabolic profile; and thyroid-stimulating hormone (due to association with thyroiditis). Lumbar puncture should be obtained in people with symptoms consistent with SPS to rule out other causes. Oligoclonal bands can be seen in about two thirds of affected people who are antibody-positive. + GARD + Stiff person syndrome
What are the treatments for Stiff person syndrome ?
How might stiff person syndrome be treated? Treatment of stiff person syndrome (SPS) focuses on the specific symptoms present in each person. Benzodiazepines may be used to treat muscle stiffness and episodic spasms; baclofen may be used in addition to benzodiazepines. Anti-seizure drugs have reportedly been effective for some people. More recently, studies have shown that intravenous immunoglobulin (IVIG) is effective in improving many of the symptoms of SPS. Research involving additional treatment options for SPS is ongoing. Additional information about the treatment of stiff person syndrome can be viewed on Medscape Reference's Web site. + GARD + Stiff person syndrome
What is (are) Prothrombin thrombophilia ?
Prothrombin thrombophilia is an inherited disorder of blood clotting. Thrombophilia is an increased tendency to form abnormal blood clots in blood vessels. People who have prothrombin thrombophilia are at somewhat higher than average risk for a type of clot called a deep venous thrombosis, which typically occur in the deep veins of the legs. Affected people also have an increased risk of developing a pulmonary embolism. However, most people with prothrombin thrombophilia never develop abnormal blood clots. Prothrombin thrombophilia is the second most common inherited form of thrombophilia after factor V Leiden thrombophilia. It is more common in Caucasian populations. This condition is caused by a particular mutation (written G20210A or 20210G>A) in the F2 gene. People can inherit one or two copies of the gene mutation from their parents. + GARD + Prothrombin thrombophilia
What are the symptoms of Prothrombin thrombophilia ?
What are the signs and symptoms of Prothrombin thrombophilia? The signs and symptoms of this condition depend on whether a person has inherited one or two copies of the F2 gene mutation from his or her parents. A person who inherits one gene mutation is called a heterozygote. Whereas a person that inherits two gene mutations (one from each parent) is considered a homozygote for this condition; although it is very rare to find individuals who are homozygous. An affected heterozygous person usually experiences mild to moderate increase in their thrombin production, which is associated with 2.5 to 3 fold greater risk of developing a venous thromboembolism. There is not enough information about risk in those who are homozygous. Some research suggests that in women, prothrombin thrombophilia is associated with a somewhat increased risk of pregnancy loss (miscarriage) and may also increase the risk of other complications during pregnancy. These complications may include pregnancy-induced high blood pressure (preeclampsia), slow fetal growth, and early separation of the placenta from the uterine wall (placental abruption). It is important to note, however, that most women with prothrombin thrombophilia have normal pregnancies. The Human Phenotype Ontology provides the following list of signs and symptoms for Prothrombin thrombophilia. If the information is available, the table below includes how often the symptom is seen in people with this condition.

Is Prothrombin thrombophilia inherited ?
How is prothrombin thrombophilia inherited? Prothrombin thrombophilia is inherited in an autosomal dominant manner. For this condition, this means that having one mutated copy of the disease-causing gene (F2) in each cell may be sufficient to cause signs or symptoms of the condition. The mutation in the F2 gene that causes prothrombin thrombophilia is called 20210G>A (also called the 20210G>A allele). An individual can be heterozygous (having the mutation in only one copy of the F2 gene) or homozygous (having a mutation in both copies of the F2 gene). Heterozygosity results in an increased risk for thrombosis; homozygosity results in more severe thrombophilia and/or increased risk for thrombosis. All individuals reported to date with prothrombin thrombophilia who are heterozygous for the 20210G>A allele have had an affected parent. Because of the relatively high prevalence of this allele in the general population, occasionally one parent is homozygous or both parents are heterozygous for this allele. When an individual who is heterozygous for the 20210G>A allele has children, each child has a 50% (1 in 2) risk to inherit that allele and also be heterozygous. An individual who is homozygous will always pass one of the 20210G>A alleles to each of his/her children. If two heterozygotes have children together, each child has a 25% (1 in 4) risk to be homozygous (having 2 mutated copies), a 50% risk to be heterozygous like each parent, and a 25% risk to inherit 2 normal copies of the F2 gene. + GARD + Prothrombin thrombophilia
How to diagnose Prothrombin thrombophilia ?
What kind of tests can determine if an individual has, or is a carrier of, prothrombin thrombophilia? No clinical signs or symptoms are specific for prothrombin thrombophilia. A confirmed diagnosis of this condition requires specific genetic testing via DNA analysis of the F2 gene, which provides instructions for making the protein prothrombin. The test identifies the presence of a common change (mutation) called 20210G>A. An individual can be a heterozygote (having one mutated copy of the F2 gene) or a homozygote (having two mutated copies). Most heterozygotes have a mildly elevated plasma concentration of prothrombin (which can be measured in a blood test) that is approximately 30% higher than normal. However, these values can vary greatly, and the range of prothrombin concentrations in heterozygotes overlaps significantly with the normal range. Therefore, plasma concentration of prothrombin is not reliable for diagnosis of this condition. Individuals interested in learning more about testing for prothrombin thrombophilia should speak with a genetics professional or other healthcare provider. + GARD + Prothrombin thrombophilia
What is (are) Acrodermatitis enteropathica ?
Acrodermatitis enteropathica (AE) is a disorder of zinc metabolism that can either be inherited or acquired. Both forms lead to the inability to absorb zinc from the intestine. The lack of zinc can cause skin inflammation with a rash (pustular dermatitis) around the mouth and/or anus; diarrhea; and abnormal nails (nail dystrophy). Irritability and emotional disturbances can also occur. The inherited form is caused by mutations in the SLC39A4 gene and inherited in an autosomal recessive pattern. The acquired form can result from diets lacking the appropriate amount of zinc. Supplemental zinc usually eliminates the symptoms of acrodermatitis enteropathica. + GARD + Acrodermatitis enteropathica

What is (are) Thalassemia ?
Thalassemia is an inherited blood disorder that reduces the production of functional hemoglobin (the protein in red blood cells that carries oxygen). This causes a shortage of red blood cells and low levels of oxygen in the bloodstream, leading to a variety of health problems. There are two main types of thalassemia, alpha thalassemia and beta thalassemia. Signs and symptoms vary but may include mild to severe anemia, paleness, fatigue, yellow discoloration of skin (jaundice), and bone problems. Beta thalassemia is caused by changes (mutations) in the HBB gene while alpha thalassemia is caused by mutations in the HBA1 and/or HBA2 genes. Both are inherited in an autosomal recessive manner. Treatment depends on the type and severity of the condition but may include blood transfusions and/or folic acid supplements. + GARD + Thalassemia
What are the symptoms of Thalassemia ?
What are the signs and symptoms of Thalassemia? The signs and symptoms vary depending on the severity of the thalassemia. For example, people affected by milder forms of thalassemia can develop mild anemia or may have no signs or symptoms of the condition at all. Intermediate forms of thalassemia can cause mild to moderate anemia and may be associated with other health problems such as slowed growth, delayed puberty, bone problems and/or an enlarged spleen. In addition to the signs and symptoms seen in intermediate thalassemia, people with severe forms of thalassemia may also experience severe anemia, poor appetite, paleness, dark urine, yellow discoloration of skin (jaundice), and enlarged liver or heart.

What causes Thalassemia ?
What causes thalassemia? There are two main types of thalassemia, alpha thalassemia and beta thalassemia, which each affect a different part of hemoglobin (the protein in red blood cells that carries oxygen). Hemoglobin is made up of two different components (subunits): beta globin and alpha globin. The HBB gene provides instructions for making beta globin, while the HBA1 and HBA2 genes provide instructions for making alpha globin. Each person has two copies of each of these genes, one inherited from the mother and one from the father. Changes (mutations) in the HBB gene lead to reduced levels of beta globin and cause beta thalassemia. Loss (deletion) of some or all of the HBA1 and/or HBA2 genes results in a shortage of alpha globin, leading to alpha thalassemia. + GARD + Thalassemia
Is Thalassemia inherited ?
How is thalassemia inherited? In general, thalassemia is inherited in an autosomal recessive manner; however, the inheritance can be quite complex as multiple genes can influence the production of hemoglobin. Most people affected by beta thalassemia have mutations in both copies of the HBB gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition; although some carriers of beta thalassemia develop mild anemia. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. The inheritance of alpha thalassemia is complicated by the fact that mutations in two different genes (HBA1 and HBA2) are associated with the condition. People have two copies of the HBA1 gene and two copies of the HBA2 gene in each cell. For each gene, one copy is inherited from the mother and one is inherited from the father. If each parent is missing at least one gene copy, their children are at risk for having alpha thalassemia. However, the exact risk and the severity of each child's condition depends on how many gene copies are lost (deleted) and which combination of the HBA1 and HBA2 genes are affected. + GARD + Thalassemia
How to diagnose Thalassemia ?
Is genetic testing available for thalassemia? Yes, genetic testing is available for HBB, HBA1 and HBA2, the genes known to cause thalassemia. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutations in the family are known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. It has additional information on genetic testing for alpha thalassemia and beta thalassemia. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. + GARD + Thalassemia
What are the treatments for Thalassemia ?
How might thalassemia be treated? The best treatment options depend on the severity of thalassemia. People affected by a mild form often need little to no treatment, while people with intermediate to severe thalassemias may require frequent blood transfusions, iron chelation therapy (treatments to remove excess iron from the body), and/or folic acid supplementation.
