Topic: Hemophagocytic lymphohistiocytosis
Question: What is (are) Hemophagocytic lymphohistiocytosis ?
Answer: Hemophagocytic lymphohistiocytosis (HLH) is a condition in which the body makes too many activated immune cells (macrophages and lymphocytes). People with HLH usually develop symptoms within the first months or years of life which may include fever, enlarged liver or spleen, cytopenia (lower-than-normal number of blood cells), and neurological abnormalities. HLH may be inherited in an autosomal recessive manner or it can have non-genetic causes in which case it is called acquired HLH. There are five subtypes of inherited HLH which are designated familial HLH, types 1-5. Each subtype is caused by a change (mutation) in a different gene. The genetic cause of type 1 is currently unknown. Types 2-5 are caused by mutations in the PRF1 gene, the UNC13D gene, the STX11 gene and the STXBP2 gene, respectively. Treatment depends on a number of factors, including the severity of symptoms, the age of onset, and the underlying cause of the condition.

Question: What are the symptoms of Hemophagocytic lymphohistiocytosis ?
Answer: What are the signs and symptoms of Hemophagocytic lymphohistiocytosis? The signs and symptoms of hemophagocytic lymphohistiocytosis typically develop during the first months or years of life. However, in rare cases, affected people may not show symptoms until later in childhood or even into adulthood. The features of this condition may include: Fever Enlarged liver and/or spleen Skin rash Lymph node enlargement Breathing problems Easy bruising and/or abnormal bleeding Kidney abnormalities Heart problems Increased risk for certain cancers (leukemia, lymphoma) Many people with this condition also develop neurologic abnormalities. The neurological symptoms vary but may include irritability, fatigue, abnormal muscle tone, seizures, neck stiffness, mental status changes, ataxia, blindness, paralysis, and/or coma. The Human Phenotype Ontology provides the following list of signs and symptoms for Hemophagocytic lymphohistiocytosis. 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) Reduced natural killer cell activity 13/13 Granulocytopenia 11/14 Neutropenia 5/7 Abnormal natural killer cell physiology - Anemia - Ataxia - Autosomal recessive inheritance - Coma - CSF pleocytosis - Encephalitis - Episodic fever - Failure to thrive - Fever - Generalized edema - Hemiplegia - Hemophagocytosis - Hepatomegaly - Hepatosplenomegaly - Hyperbetalipoproteinemia - Hypertonia - Hypertriglyceridemia - Hypoalbuminemia - Hypoalphalipoproteinemia - Hypofibrinogenemia - Hyponatremia - Hypoproteinemia - Increased circulating very-low-density lipoprotein cholesterol - Increased CSF protein - Increased intracranial pressure - Increased serum ferritin - Increased total bilirubin - Irritability - Jaundice - Leukopenia - Lymphadenopathy - Meningitis - Muscular hypotonia - Prolonged partial thromboplastin time - Prolonged prothrombin time - Seizures - Splenomegaly - Tetraplegia - Thrombocytopenia - 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.

Question: What causes Hemophagocytic lymphohistiocytosis ?
Answer: What causes hemophagocytic lymphohistiocytosis? There are inherited and non-inherited (acquired) causes of hemophagocytic lymphohistiocytosis (HLH). There are five subtypes of inherited HLH which are designated familial HLH, types 1-5. Each subtype is caused by a change (mutation) in a different gene that helps regulate the immune system. The genetic cause of familial HLH, type 1 is currently unknown. Familial HLH, type 2 is caused by mutations in the PRF1 gene. Familial HLH, type 3 is caused by mutations in the UNC13D gene. Familial HLH, type 4 is caused by mutations in the STX11 gene. Familial HLH, type 5 is caused by mutations in the STXBP2 gene.  All of the genes that cause HLH serve as the instructions for proteins that help destroy or turn off activated immune cells that are no longer needed. Changes in these genes lead to an overproduction of immune cells which results in an excessive immune response and the many signs and symptoms of familial HLH. The acquired causes of HLH include: infection, medications that suppress the immune system, autoimmune diseases, immunodeficiencies, certain types of cancer and/or metabolic diseases.

Question: Is Hemophagocytic lymphohistiocytosis inherited ?
Answer: Is hemophagocytic lymphohistiocytosis inherited? Hemophagocytic lymphohistiocytosis (HLH) may be inherited or acquired (due to non-genetic factors). Familial HLH is inherited in an autosomal recessive manner. This means that to be affected, a person must have a change (mutation) in both copies of the responsible 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. 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. Acquired HLH is not inherited. The non-genetic causes of HLH include: infection, medications that suppress the immune system, autoimmune diseases, immunodeficiencies, certain types of cancer and/or metabolic diseases.

Question: How to diagnose Hemophagocytic lymphohistiocytosis ?
Answer: Is genetic testing available for hemophagocytic lymphohistiocytosis? Yes. Clinical genetic testing is available for the four genes known to cause familial hemophagocytic lymphohistiocytosis, types 2-5. Carrier testing for at-risk relatives and prenatal testing are possible if the two disease-causing mutations in the family are known. Molecular genetic testing is not available for familial hemophagocytic lymphohistiocytosis, type 1 because the genetic cause is currently unknown. Genetic testing is not available for acquired HLH because it is caused by non-genetic factors. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. 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. How is hemophagocytic lymphohistiocytosis diagnosed? A diagnosis of hemophagocytic lymphohistiocytosis (HLH) is based on the presence of certain signs and symotoms. A person is considered affected by this condition if they have at least five of the following symptoms: Fever Enlarged spleen Cytopenia (lower-than-normal number of blood cells) Elevated levels of triglycerides or fibrinogen in the blood Hemophagocytosis (the destruction of certain types of blood cells by histiocytes) on bone marrow, spleen or lymph node biopsy Decreased or absent NK cell activity High levels of ferritin in the blood Elevated blood levels of CD25 (a measure of prolonged immune cell activation) The diagnosis of familial HLH, types 2-5 can be confirmed with genetic testing.

Question: What are the treatments for Hemophagocytic lymphohistiocytosis ?
Answer: How might hemophagocytic lymphohistiocytosis be treated? The best treatment options for hemophagocytic lymphohistiocytosis (HLH) are determined by a number of factors, including the severity of symptoms, the age of onset, and the underlying cause of the condition. In acquired HLH, it is often necessary to treat the underlying condition. For example, antiobiotics or antiviral medications can be used to treat or prevent infections that may have triggered the exaggerated immune response. Allogeneic hematopoietic cell transplantation is considered a cure for familial HLH. It is often recommended that people with confirmed or suspected familial HLH undergo this treatment as early in life as possible. Prior to hematopoietic cell transplanation, affected people are usually treated with chemotherapy and/or immunotherapy to destroy excess immune cells which can lead to life-threatening inflammation.

Topic: Glucose transporter type 1 deficiency syndrome
Question: What is (are) Glucose transporter type 1 deficiency syndrome ?
Answer: Glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome) is an inherited condition that affects the nervous system. Signs and symptoms generally develop within the first few months of life and may include recurrent seizures (epilepsy) and involuntary eye movements. Affected people may also have microcephaly (unusually small head size) that develops after birth, developmental delay, intellectual disability and other neurological problems such as spasticity, ataxia (difficulty coordinating movements), and dysarthria. Approximately 10% of affected people have the "non-epileptic" form of GLUT1 deficiency syndrome which is associated with all the typical symptoms of the condition without seizures. GLUT1 deficiency syndrome is caused by changes (mutations) in the SLC2A1 gene and is inherited in an autosomal dominant manner. Although there is currently no cure for GLUT1 deficiency syndrome, a special diet (called a ketogenic diet) may help alleviate symptoms.

Question: What causes Glucose transporter type 1 deficiency syndrome ?
Answer: What causes glucose transporter type 1 deficiency syndrome? Glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome) is caused by changes (mutations) in the SLC2A1 gene. This gene encodes a protein that helps transport glucose (a simple sugar) into cells where it is used as fuel. The protein is particularly important in the central nervous system since glucose is the brain's main source of energy. SLC2A1 mutations impair the function of the protein. This significantly reduces the amount of glucose available to brain cells leading to the many signs and symptoms associated with GLUT1 deficiency syndrome.

Question: Is Glucose transporter type 1 deficiency syndrome inherited ?
Answer: Is glucose transporter type 1 deficiency syndrome inherited? Glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome) is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with GLUT1 deficiency syndrome has a 50% chance with each pregnancy of passing along the altered gene to his or her child.

Topic: Biotinidase deficiency
Question: What is (are) Biotinidase deficiency ?
Answer: Biotinidase deficiency is an inherited disorder in which the body is unable to recycle the vitamin biotin. The disorder may become apparent in the first few months of life, or later in childhood. The more severe form of the disorder is called 'profound biotinidase deficiency' and may cause delayed development, seizures, weak muscle tone (hypotonia), breathing problems, hearing and vision loss, problems with movement and balance (ataxia), skin rashes, hair loss (alopecia), and a fungal infection called candidiasis. The milder form is called 'partial biotinidase deficiency'; without treatment, affected children may experience hypotonia, skin rashes, and hair loss. In some cases, these symptoms only appear during illness, infection, or other times of stress on the body. Biotinidase deficiency is caused by mutations in the BTD gene and is inherited in an autosomal recessive manner. Lifelong treatment with biotin can prevent symptoms and complications from occurring or improve them if they have already developed.

Answer: What are the signs and symptoms of Biotinidase deficiency? The signs and symptoms of biotinidase deficiency typically appear within the first few months of life, but the age of onset varies. Children with profound biotinidase deficiency, the more severe form of the condition, may have seizures, weak muscle tone (hypotonia), breathing problems, and delayed development. If left untreated, the disorder can lead to hearing loss, eye abnormalities and loss of vision, problems with movement and balance (ataxia), skin rashes, hair loss (alopecia), and a fungal infection called candidiasis. Immediate treatment and lifelong management with biotin supplements can prevent many of these complications. Partial biotinidase deficiency is a milder form of this condition.

Topic: Autoimmune polyglandular syndrome type 1
Question: What is (are) Autoimmune polyglandular syndrome type 1 ?
Answer: Autoimmune polyglandular syndrome type 1 is an inherited autoimmune condition that affects many of the body's organs. Symptoms often begin in childhood or adolescence and may include mucocutaneous candidiasis, hypoparathyroidism, and Addison disease. Affected individuals typically have at least two of these features, and many have all three. This syndrome can cause a variety of additional signs and symptoms, although they occur less often. Complications of this disorder can affect the skin and nails, the gonads (ovaries and testicles), the eyes, the thyroid, and the digestive system. Type 1 diabetes also occurs in some patients with this condition. Mutations in the AIRE gene cause autoimmune polyglandular syndrome, type 1. This condition is inherited in an autosomal recessive fashion.
