Topic: Pyruvate kinase deficiency
Question: What are the symptoms of Pyruvate kinase deficiency ?
Answer: What are the signs and symptoms of Pyruvate kinase deficiency? The signs and symptoms of pyruvate kinase deficiency may vary greatly from person to person, but usually include the breakdown of red blood cells resulting in hemolytic anemia, a yellowing of the whites of the eyes (icterus), fatigue, lethargy, recurrent gallstones, jaundice, and pale skin (pallor).  In more severe cases, the first signs and symptoms may appear in utero in the form of hydrops fetalis, a condition in which abnormal amounts of fluid build up in two or more body areas of the fetus. Newborns may present with prolonged jaundice and anemia. Older children may be pale (due to anemia) and have intermittent episodes of jaundice. Mild cases may escape detection until adulthood. Although the anemia tends to stabilize in adulthood, episodes of anemia may occur with acute infections, stress, and pregnancy. The Human Phenotype Ontology provides the following list of signs and symptoms for Pyruvate kinase 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) Intrauterine growth retardation 5% Nonimmune hydrops fetalis 5% Abnormality of the amniotic fluid - Autosomal recessive inheritance - Cholecystitis - Cholelithiasis - Chronic hemolytic anemia - Increased red cell osmotic fragility - Jaundice - Reticulocytosis - Splenomegaly - Unconjugated hyperbilirubinemia - 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.

Topic: Pyruvate kinase deficiency
Question: What causes Pyruvate kinase deficiency ?
Answer: What causes pyruvate kinase deficiency? In most cases, pyruvate kinase deficiency is caused by mutations in the PKLR gene. More than 100 different mutation in the PKLR gene have been detected. Medical conditions, such as acute leukemia, preleukemia, and refractory sideroblastic anemia, as well as complications from chemotherapy, can cause an acquired pyruvate kinase deficiency. This type is more common and milder than the hereditary type.

Topic: Pyruvate kinase deficiency
Question: Is Pyruvate kinase deficiency inherited ?
Answer: How is pyruvate kinase deficiency inherited? Pyruvate kinase deficiency is inherited in an autosomal recessive fashion, which means that a child must inherit a gene with a disease-causing mutation from both parents to develop the disorder. The gene that causes pyruvate kinase deficiency is called the PKLR gene that is located on chromosome 1q21.  Although the inheritance is clinically autosomal recessive, most affected individuals are compound heterozygous for two different mutant alleles. It is estimated that approximatly 1 in 100 people carry one copy of a disease-causing mutation in the PKLR gene.  Carriers of one non-working PKLR gene usually have moderatly reduced levels of pyruvate kinase activity but do not develop clinical symptoms. It is possible that carriers of a mutant pyruvate kinase genemay have a protective advantage against malaria in areas where the disease is endemic.

Question: What are the treatments for Pyruvate kinase deficiency ?
Answer: How might pyruvate kinase deficiency be treated? Mild cases require no treatment. People with severe anemia may need blood transfusions.  In newborns with dangerous levels of jaundice, a health care provider may recommend an exchange transfusion. Surgical removal of the spleen (splenectomy) may also be necessary to help reduce the destruction of red blood cells. However, this does not help in all cases. With small children, this is delayed as long as possible to allow the immune system to mature. Other treatment is symptomatic and supportive. Someone who had a splenectomy should receive the pneumococcal vaccine at recommended intervals. They also should receive preventive antibiotics until age 5.

Topic: Localized scleroderma
Question: What is (are) Localized scleroderma ?
Answer: Localized scleroderma is characterized by thickening of the skin from excessive collagen deposits. Collagen is a protein normally present in our skin that provides structural support. However, when too much collagen is made, the skin becomes stiff and hard. Localized types of scleroderma are those limited to the skin and related tissues and, in some cases, the muscle below. Internal organs are not affected by localized scleroderma, and localized scleroderma can never progress to the systemic form of the disease. Often, localized conditions improve or go away on their own over time, but the skin changes and damage that occur when the disease is active can be permanent. For some people, localized scleroderma is serious and disabling. There are two generally recognized types of localized scleroderma: morphea and linear.

Topic: Localized scleroderma
Question: What are the symptoms of Localized scleroderma ?
Answer: What are the signs and symptoms of Localized scleroderma? Signs and symptoms of morphea, include: Hardening of the skin. Thickening of the skin. Discoloration of the affected skin to look lighter or darker than the surrounding area.  The first signs of the disease are reddish patches of skin that thicken into firm, oval-shaped areas. The center of each patch becomes ivory colored with violet borders. These patches sweat very little and have little hair growth. Patches appear most often on the chest, stomach, and back. Sometimes they appear on the face, arms, and legs. Morphea usually affects only the uppermost layers of your skin, but in some cases may involve fatty or connective tissue below your skin. Morphea can be either localized or generalized. Localized morphea limits itself to one or several patches, ranging in size from a half-inch to 12 inches in diameter. The condition sometimes appears on areas treated by radiation therapy. Some people have both morphea and linear scleroderma (which is characterized by a single line or band of thickened and/or abnormally colored skin). The disease is referred to as generalized morphea when the skin patches become very hard and dark and spread over larger areas of the body. The Human Phenotype Ontology provides the following list of signs and symptoms for Localized scleroderma. 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.

Topic: Localized scleroderma
Question: What causes Localized scleroderma ?
Answer: What causes morphea? The exact cause of morphea is unknown. It is not infectious. It is not hereditary, though, similar problems may present in other family members. It's believed that a reaction of the immune system plays a role in the development of this rare condition. Experts have explored a possible connection between morphea and infection, such as measles or chickenpox, but recent research doesn't support this theory. Other factors that may be associated with the onset of morphea include radiation therapy or repeated trauma to the affected area.

Topic: Localized scleroderma
Question: What are the treatments for Localized scleroderma ?
Answer: How might morphea be treated? There is no cure for morphea. Treatment is aimed at controlling the signs and symptoms and slowing the spread of the disease. The precise treatment depends on the extent and severity of the condition. Some people with mild morphea may choose to defer treatment. For people with morphea involving only the skin who want treatment, treatment may involve UVA1 phototherapy (or else broad band UVA, narrow band UVB, or PUVA), tacrolimus ointment, or steroid shots. Other treatment options include high potency steroid creams, vitamin D analog creams, or imiquimod. If a persons morphea is rapidly progressive, severe, or causing significant disability treatment options may include systemic steroids (glucocorticoids) and methotrexate. People with morphea should be monitored for joint changes and referred for physical and occupational therapy as appropriate.

Topic: Infantile-onset ascending hereditary spastic paralysis
Question: What is (are) Infantile-onset ascending hereditary spastic paralysis ?
Answer: Infantile-onset ascending hereditary spastic paralysis is a motor neuron disease characterized by progressive weakness and stiffness of muscles in the arms, legs, and face. Initial symptoms usually occur within the first 2 years of life and include weakness of the legs, leg muscles that are abnormally tight and stiff, and eventual paralysis of the legs. Over time, muscle weakness and stiffness travels up (ascends) the body from the legs to the head. Infantile-onset ascending hereditary spastic paralysisis caused by mutations in the ALS2 gene, and this condition is inherited in an autosomal recessive pattern.

Topic: Prader-Willi syndrome
Question: What is (are) Prader-Willi syndrome ?
Answer: Prader-Willi syndrome (PWS) is a genetic condition that affects many parts of the body. Infants with PWS have severe hypotonia (low muscle tone), feeding difficulties, and slow growth. In later infancy or early childhood, affected children typically begin to eat excessively and become obese. Other signs and symptoms often include short stature, hypogonadism, developmental delays, cognitive impairment, and distinctive behavioral characteristics such as temper tantrums, stubbornness, and obsessive-compulsive tendencies. PWS is caused by missing or non-working genes on chromosome 15. Most cases are not inherited and occur randomly. Rarely, a genetic change responsible for PWS can be inherited. Management of PWS generally depends on the affected person's age and symptoms.

Topic: Prader-Willi syndrome
Question: What causes Prader-Willi syndrome ?
Answer: What causes Prader-Willi syndrome? Prader-Willi syndrome (PWS) is caused by the loss of active genes in a specific region of chromosome 15. People normally inherit one copy of chromosome 15 from each parent. Some genes on chromosome 15 are only active (or "expressed") on the copy that is inherited from a person's father (the paternal copy). When genes are only active if inherited from a specific parent, it is called genomic imprinting. About 70% of cases of PWS occur when a person is missing specific genes on the long arm of the paternal copy of chromosome 15. This is called a deletion. While there are copies of these same genes on the maternal copy of chromosome 15, the maternal copies of these genes are not expressed.   In about 25% of cases, PWS is due to a person inheriting only 2 maternal copies of chromosome 15, instead of one copy from each parent. This is called maternal uniparental disomy. Rarely (in about 2% of cases), PWS is caused by a rearrangement of chromosome material called a translocation, or by a change (mutation) or other defect that abnormally inactivates genes on the paternal chromosome 15. Each of these genetic changes result in a loss of gene function on part of chromosome 15, likely causing the characteristic features of PWS.

Topic: Prader-Willi syndrome
Question: Is Prader-Willi syndrome inherited ?
Answer: Is Prader-Willi syndrome inherited? Most cases of Prader-Willi syndrome (PWS) are not inherited and are due to random events during the formation of egg or sperm cells, or in early fetal development. This is usually the case when PWS is caused by a deletion in the paternal chromosome 15, or by maternal uniparental disomy. However in rare cases, a genetic change responsible for PWS can be inherited. The risk to family members of a person with PWS depends on the genetic cause of the condition in the affected person. Because the various genetic causes of PWS are complex, people seeking information about specific risks to themselves or family members are encouraged to speak with a genetics professional. More information about the causes of PWS can be viewed on our Web site here.

Topic: Prader-Willi syndrome
Question: How to diagnose Prader-Willi syndrome ?
Answer: How is Prader-Willi syndrome diagnosed? There are clinical diagnostic criteria for Prader-Willi syndrome (PWS) that were developed in the past that continue to be useful. These criteria can be viewed on the National Institute of Health's NICHD Web site. However, the current mainstay of a diagnosis when PWS is suspected is a form of genetic testing called DNA methylation testing. This testing can detect abnormal, parent-specific imprinting on the region of chromosome 15 that is responsible for PWS. It determines whether the region is maternally inherited only (i.e., the paternally contributed region is absent) and confirms a diagnosis in more than 99% of affected people. DNA methylation testing is especially important in people who have non-classic features, or are too young to show enough features to make the diagnosis based on signs and symptoms alone.
