Question:  What are the symptoms of Type 1 plasminogen deficiency ?
Answer: What are the signs and symptoms of Type 1 plasminogen deficiency? Type 1 plasminogen deficiency causes reduced levels of functional plasminogen. The rare inflammatory disease mainly affects the mucous membrances in different body sites. Although the symptoms and their severity may vary from person to person, the most common clinical manifestation is ligneous conjunctivitis, characterized by development of fibrin-rich, woodlike ('ligneous') pseudomembranous lesions. Involvement of the cornea may result in blindness. Other, less common manifestations are ligenous gingivitis, otitis media, ligneous bronchitis and pneumonia, involvement of the gastrointestinal or female genital tract, juvenile colloid milium of the skin (condition in which clear papules develop on sun-exposed areas of the skin), and congenital hydrocephalus. Although the condition is known to cause thrombotic events in mice, no reports of venous thrombosis in humans with the condition have been documented.[826] The Human Phenotype Ontology provides the following list of signs and symptoms for Type 1 plasminogen deficiency. 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) Abnormality of the eye 90% Abnormality of the oral cavity 50% Abnormality of the intestine 7.5% Abnormality of the middle ear 7.5% Abnormality of the respiratory system 7.5% Dandy-Walker malformation 7.5% Hydrocephalus 7.5% Nephrolithiasis 7.5% Polycystic ovaries 7.5% Nephritis 5% Abnormality of metabolism/homeostasis - Abnormality of the cardiovascular system - Abnormality of the ear - Abnormality of the larynx - Abnormality of the skin - Autosomal recessive inheritance - Blindness - Cerebellar hypoplasia - Conjunctivitis - Duodenal ulcer - Gingival overgrowth - Gingivitis - Infantile onset - Macrocephaly - Periodontitis - Recurrent upper respiratory tract infections - 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 Type 1 plasminogen deficiency ?
Answer: What causes plasminogen deficiency, type 1? Plasminogen deficiency, type 1 is caused by a mutation in a gene encoding plasminogen, an enzyme whose function is to dissolve fibrin clots. Fibrin clots form scabs at a wound site.
Question:  Is Type 1 plasminogen deficiency inherited ?
Answer: Is plasminogen deficiency, type 1 inherited? If so, in what manner? Plasminogen deficiency, type 1 is inherited in an autosomal recessive fashion, which means that an individual must inherit two disease-causing mutated copies of the plasminogen gene in order to have the condition and exhibit symptoms.
Question:  What are the treatments for Type 1 plasminogen deficiency ?
Answer: How might type 1 plasminogen deficiency be treated? The treatment options available for type 1 plasminogen deficiency are few. However, some researchers have shown that the ligneous lesions can be reversed by plasminogen infusion, with changes occurring within 3 days and restored to normal after 2 weeks of treatment. Recurrence has been prevented by daily injections with plasminogen sufficient to achieve plasma concentrations to approximately 40% of the normal amount of plasminogen. Treatment with topical plasminogen has also been successful and resulted in dramatic improvement and complete resolution of the membranes. In some women, treatment with oral contraceptives have resulted in an increase in the levels of plasminogen and some resolution of the pseudomembrane.
Question:  What is (are) Pyruvate dehydrogenase deficiency ?
Answer: Pyruvate dehydrogenase deficiency is metabolic disorder associated with abnormal function of the mitochondria in cells, thus depriving the body of energy. Progressive neurological symptoms usually start in infancy but may be evident at birth, or in later childhood; these symptoms may include developmental delay, intermittent ataxia, poor muscle tone (hypotonia), abnormal eye movements, or seizures. Severe lethargy, poor feeding, and tachypnea (rapid breathing) commonly occur, especially during times of illness, stress, or high carbohydrate intake. Childhood-onset forms of the condition are often associated with intermittent periods of illness but normal neurological development. Prognosis is difficult to predict due to the many causes of the condition, but in most cases of neonatal and infantile onset, prognosis is described as poor. The most common form of pyruvate dehydrogenase deficiency is caused by mutations in the E1 alpha gene, and is inherited in an X-linked dominant manner; all other forms are caused by various genes and are inherited in an autosomal recessive manner. In addition to directly treating acidosis and providing alternative energy for the body, treatment typically includes dietary supplementation with thiamine, carnitine, and lipoic acids, although not all individuals respond to this therapy.
Question:  What causes Pyruvate dehydrogenase deficiency ?
Answer: What causes pyruvate dehydrogenase deficiency? Pyruvate dehydrogenase (PDH) deficiency is usually caused by a deficiency of one or more enzymes or cofactors (such as thiamine) that are needed for an important chemical reaction in the cells of the body. These enzymes or cofactors are part of the pyruvate dehydrogenase complex and normally convert (or aid in converting) a chemical called pyruvate to another chemical called acetyl-coenzyme A (CoA), which is one of two important chemicals the body needs to make citrate for the cells. Because pyruvate cannot be converted to acetyl-CoA, there is too much pyruvate in the cells, which then gets used to produce more lactic acid (which is toxic in large amounts) and alanine; there is also not enough citrate being made by the body. Citrate is the first step in another important group of chemical reactions called the citric acid cycle, which then cannot proceed. The body tries to make alternate pathways to produce more acetyl-CoA, but there is still not enough energy made in the body, especially in the central nervous system (CNS). The amount of energy that is deficient depends on the amount of the enzyme that is deficient. The condition is sometimes referred to as pyruvate dehydrogenase complex (PDHC) deficiency because there is a "complex" of three enzymes normally used in the reaction; when any one or more of the enzymes needed for the above-described reaction are deficient, the condition results. The most common form of pyruvate dehydrogenase deficiency is caused by mutations in the X-linked dominant E1 alpha gene; all other causes are thought to be due to mutations in recessive genes.
Question:  Is Pyruvate dehydrogenase deficiency inherited ?
Answer: How is pyruvate dehydrogenase deficiency inherited? Pyruvate dehydrogenase deficiency is most commonly caused by mutations in the E1 alpha gene, which is located on the X chromosome (one of the sex chromosomes) and is typically inherited in an X-linked dominant manner. Dominant inheritance occurs when an abnormal gene from one parent is capable of causing disease, even though a matching gene from the other parent is normal. The abnormal gene "dominates" the gene pair. Females have two X chromosomes (one from each parent) and males have one X chromosome from the mother and one Y chromosome from the father. For an X-linked dominant disorder, because one mutated gene is enough to cause the condition, both males and females can have the condition. Because males have no other copy of the X chromosome with a working gene, affected males usually have more severe disease than affected females (who have another X chromosome with a working gene).  If the father carries the abnormal X gene, all of his daughters will inherit the disease and none of his sons will have the disease. If the mother carries the abnormal X gene, there is a 50% (1 in 2) chance for each child (whether male or female) to inherit the disease. The condition may also be caused by a new mutation that first appears in an affected individual, without either parent carrying an abnormal gene for the condition. The other genes that are thought to cause pyruvate dehydrogenase deficiency appear to be inherited in an autosomal recessive manner and are not on the sex chromosomes. This means that two non-working copies of the gene that is causing the condition must be present for an individual to have the condition. When an individual has an autosomal recessive condition, each of that person's parents have a non-working copy of the gene and are referred to as "carriers." When 2 carriers for the same condition are having children, there is a 25% (1 in 4) chance for each child to have the condition, a 50% (1 in 2) chance for each child to be a carrier like each of the parents, and a 25% chance for each child to not have the condition and not be a carrier.
Question:  How to diagnose Pyruvate dehydrogenase deficiency ?
Answer: Is genetic testing available for pyruvate dehydrogenase deficiency? Genetic testing is available for pyruvate dehydrogenase deficiency. GeneTests lists the names of laboratories that are performing genetic testing for pyruvate dehydrogenase deficiency. To view the contact information for the clinical laboratories conducting testing click here. Please note: Most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, if you are interested in learning more, you will need to work with a health care provider or a genetics professional. How is pyruvate dehydrogenase deficiency diagnosed? The diagnosis of pyruvate dehydrogenase (PDH) deficiency may be considered in any individual with early-onset neurological disease, especially if it appears to be associated with structural abnormalities in the brain and unexplained lactic acidosis. When lactic acid (also called lactate) and pyruvate in the blood do not seem to be significantly high, an important clue to the diagnosis may be high concentrations of lactate and/or pyruvate in the cerebrospinal fluid (the fluid that surrounds the brain and spinal cord). Additionally, magnetic resonance spectroscopy (MRS) of the brain may show concentrations of lactate in the central nervous system. Analysis of serum and urine amino acids usually shows hyperalaninemia (high levels of the amino acid alanine). When lactic acidosis is present, other disorders involving pyruvate abnormalities are part of the differential diagnosis. However, in all of these conditions, the diagnosis is based on specific laboratory tests. Specific enzyme tests have been designed which measure both the individual's overall PDH activity, as well as each separate component of the complex (because any defect in the complex may cause the condition). The vast majority of individuals with PDH deficiency are found to be deficient in the El enzyme, but abnormalities have also been detected in other components.
Question:  What are the treatments for Pyruvate dehydrogenase deficiency ?
Answer: How might pyruvate dehydrogenase deficiency be treated? Treatment of pyruvate dehydrogenase (PDH) deficiency rarely influences the course of the disease, but goals include stimulating the pyruvate dehydrogenase complex (PDHC), providing alternative sources of energy, and preventing immediate, acute worsening of the condition. However, even with treatment, damage to the central nervous system is common. Lactic acid accumulation may be lessened by giving a high fat/low carbohydrate (ketogenic) diet, but this does not alleviate the neurological symptoms, because structural damage in the brain is typically present from before birth. There is some evidence that a medication called dichloroacetate may reduce the metabolic issues in some patients. The standard of care is to supplement cofactors, which are substances in the body that help the chemical reactions in the cells to occur; these include thiamine, carnitine, and lipoic acid. The individuals with PDH deficiency that respond to these cofactors (especially thiamine) usually have a better outcome. However, giving all of these cofactors to all patients with PDH deficiency is typical in order to optimize pyruvate dehydrogenase complex function. Oral citrate is often used to treat acidosis.

Question:  What is (are) Fumarase deficiency ?
Answer: Fumarase deficiency is an inherited condition that primarily affects the nervous system, especially the brain. Affected infants may have microcephaly, abnormal brain structure, severe developmental delay, weak muscle tone (hypotonia), failure to thrive, seizures, and/or distinctive facial features. Other signs and symptoms may include hepatosplenomegaly, an excess of red blood cells (polycythemia), and/or or deficiency of white blood cells (leukopenia). Affected individuals usually survive only a few months, but a few have lived into early adulthood. This condition is caused by mutations in the FH gene and is inherited in an autosomal recessive manner. No effective treatment is currently available.
Question:  What are the symptoms of Fumarase deficiency ?
Answer: What are the signs and symptoms of Fumarase deficiency? Most newborns with fumarase deficiency show severe neurologic abnormalities, including poor feeding, failure to thrive, and poor muscle tone (hypotonia). Early-onset infantile encephalopathy (altered brain structure or function), seizures, and severe developmental delay with microcephaly are also common. Other signs and symptoms may include infantile spasms, abnormal posturing of the limbs, and autistic features. Distinctive facial features have been reported in some affected individuals and have included an unusually prominent forehead (frontal bossing); low-set ears; a small jaw (micrognathia); widely-spaced eyes (ocular hypertelorism); depressed nasal bridge; and high-arched palate. Other findings in affected individuals can include neonatal polycythemia (an excess of red blood cells); leukopenia (deficiency of white blood cells); neutropenia; enlarged liver and spleen (hepatosplenomegaly); and pancreatitis. Many children with this condition do not survive infancy or childhood. Those surviving beyond childhood have severe psychomotor deficits.

Question:  What causes Fumarase deficiency ?
Answer: What causes fumarase deficiency? Mutations in the FH gene cause fumarase deficiency. The FH gene provides instructions for making an enzyme called fumarase, which participates in a series of reactions allowing cells to use oxygen and generate energy. Mutations in the FH gene disrupt the enzyme's ability to do its job. Disruption of the process that generates energy for cells is particularly harmful to cells in the developing brain, thus resulting in the signs and symptoms of fumarase deficiency.
Question:  What are the treatments for Fumarase deficiency ?
Answer: How might fumarase deficiency be treated? There is currently no effective treatment for fumarase deficiency. Nutritional intervention may be appropriate for children with feeding difficulties. Physical therapy and wheelchairs can also be useful for some individuals.

Question:  What is (are) Dowling-Degos disease ?
Answer: Dowling-Degos disease is a skin condition characterized by a lacy or net-like (reticulate) pattern of abnormally dark skin coloring (hyperpigmentation), particularly in the body's folds and creases. Other features may include dark lesions on the face and back that resemble blackheads, red bumps around the mouth that resemble acne, depressed or pitted scars on the face similar to acne scars but with no history of acne, cysts within hair follicles (pilar cysts) on the scalp, and rarely, patches of skin that are unusually light in color (hypopigmented). Symptoms typically develop in late childhood or in adolescence and progress over time. While the skin changes caused by Dowling-Degos disease can be bothersome, they typically don't cause health problems. Dowling-Degos disease is caused by mutations in the KRT5 gene. This condition is inherited in an autosomal dominant pattern.
