Greig cephalopolysyndactyly syndrome (GCPS) is a congenital disorder that affects development of the limbs, head, and face. Findings might include an extra finger or toe (polydactyly), fusion of the skin between the fingers or toes (syndactyly), widely spaced eyes (ocular hypertelorism), and an abnormally large head size (macrocephaly).The features of this syndrome are highly variable, ranging from polydactyly and syndactyly of the upper and/or lower limbs to seizure, hydrocephalus , and intellectual disability. Progression of GCPS is dependent on severity. Greig cephalopolysyndactyly syndrome is caused by mutations in the GLI3 gene. This condition is inherited in an autosomal dominant pattern. Treatment is symptomatic.
What are the signs and symptoms of Greig cephalopolysyndactyly syndrome? The symptoms of Greig cephalopolysyndactyly syndrome (GCPS) are highly variable, ranging from mild to severe. People with this condition typically have limb anomalies, which may include one or more extra fingers or toes (polydactyly), an abnormally wide thumb or big toe (hallux), and the skin between the fingers and toes may be fused (cutaneous syndactyly). This disorder is also characterized by widely spaced eyes (ocular hypertelorism), an abnormally large head size (macrocephaly), and a high, prominent forehead. Rarely, affected individuals may have more serious medical problems including seizures, developmental delay, and intellectual disability. The Human Phenotype Ontology provides the following list of signs and symptoms for Greig cephalopolysyndactyly 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.

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.
What causes Greig cephalopolysyndactyly syndrome? Mutations in the GLI3 gene cause Greig cephalopolysyndactyly syndrome (GCPS). The GLI3 gene provides instructions for making a protein that controls gene expression, which is a process that regulates whether genes are turned on or off in particular cells. By interacting with certain genes at specific times during development, the GLI3 protein plays a role in the normal shaping (patterning) of many organs and tissues before birth. Different genetic changes involving the GLI3 gene can cause GCPS. In some cases, the condition results from a chromosome abnormalitysuch as a large deletion or rearrangement of genetic materialin the region of chromosome 7 that contains the GLI3 gene. In other cases, a mutation in the GLI3 gene itself is responsible for the disorder. Each of these genetic changes prevents one copy of the gene in each cell from producing any functional protein. It remains unclear how a reduced amount of this protein disrupts early development and causes the characteristic features of GCPS.
How is Greig cephalopolysyndactyly syndrome inherited? Greig cephalopolysyndactyly syndrome (GCPS) is often inherited in an autosomal dominant pattern. This means that to be affected, a person only needs a change (mutation) in one copy of the GLI3 gene in each cell. In some cases, an affected person inherits a gene mutation or chromosomal abnormality from one affected parent. Other cases occur in people with no history of the condition in their family. A person with GCPS syndrome has a 50% chance with each pregnancy of passing the altered gene to his or her child.
Is genetic testing available for Greig cephalopolysyndactyly syndrome? Yes. GLI3 is the only gene known to be associated with Greig cephalopolysyndactyly syndrome (GCPS). Genetic testing is available to analyze the GLI3 gene for mutations. Mutations involving GLI3 can be identified in greater than 75% of people with GCPS. How is Greig cephalopolysyndactyly syndrome diagnosed?  Greig cephalopolysyndactyly syndrome (GCPS) is diagnosed based on clinical findings and family history. Major findings of GCPS include: an abnormally large head size (macrocephaly) greater than the 97th percentile widely spaced eyes (ocular hypertelorism) limb anomalies including extra fingers or toes (polydactyly) fused skin between the fingers and toes (cutaneous syndactyly) A diagnosis is established in a first degree relative of a known affected individual if that person has polydactyly with or without syndactyly or craniofacial features (macrocephaly, widely spaced eyes). A diagnosis is additionally established in a person who has features of GCPS and a mutation in the GLI3 gene.
How might Greig cephalopolysyndactyly syndrome be treated? Treatment for Greig cephalopolysyndactyly syndrome (GCPS) is symptomatic. Treatment might include elective surgical repair of polydactyly. Evaluation and treatment of hydrocephalus might additionally occur if hydrocephalus is present.  Hydrocephalus is a condition characterized by excessive accumulation of fluid in the brain. This fluid is cerebrospinal fluid (CSF) - a clear fluid that surrounds the brain and spinal cord. Excess CSF builds up when it cannot drain from the brain due to a blockage in a passage through which the fluid normally flows. This excess fluid causes an abnormal widening of spaces in the brain called ventricles; this can create harmful pressure on brain tissue. Treatment of hydrocephalus often includes surgical insertion of a shunt system-in which a catheters (tubes) are surgically placed behind both ears. A valve (fluid pump) is placed underneath the skin behind the ear and is connected to both catheters. When extra pressure builds up around the brain, the valve opens, and excess fluid drains through the catheter. This helps lower pressure within the skull (intracranial pressure).

Sideroblastic anemia is a heterogeneous group of blood disorders characterized by an impaired ability of the bone marrow to produce normal red blood cells. The iron inside red blood cells is inadequately used to make hemoglobin, despite adequate or increased amounts of iron. Abnormal red blood cells called sideroblasts are found in the blood of people with these anemias. Sideroblastic anemias are classified as hereditary, acquired, and reversible.
What causes sideroblastic anemia? The exact cause of sideroblastic anemia in many patients remains unknown. Reversible sideroblastic anemia can be caused by alcohol, isoniazid, pyrazinamide, cycloserine (a prescription antibiotic that may cause anemia, peripheral neuritis, or seizures by acting as a pyridoxine antagonist or increasing excretion of pyridoxine), chloramphenicol, or copper deficiency. The hereditary forms may be passed through families in autosomal recessive, autosomal dominant, or X-linked patterns.
How is sideroblastic anemia diagnosed? The principle feature of sideroblastic anemia is slowly progressive, mild, life-long anemia which often goes unnoticed. Symptoms of iron overload may lead to the discovery of this underlying disorder. The history and clinical findings, together with laboratory findings, usually permit accurate diagnosis of each type. Laboratory evaluation may include complete blood count, iron studies, free erythrocyte protoporphyrin levels, MRI, bone marrow aspiration and liver biopsy. Molecular defects can be identified in several hereditary forms and in some patients with acquired sideroblastic anemia.
How might sideroblastic anemia be treated? The treatment of sideroblastic anemia is directed at controlling symptoms of anemia and preventing organ damage from iron overload. Many patients see improvement with increased vitamin B6 intake - either through diet (potatoes, bananas, raisin bran cereal, lentils, liver, turkey, and tuna are good sources) or supplements - with red blood cell counts returning to near-normal values. Folic acid supplementation may also be beneficial. Those that do not respond to vitamin supplementation require blood transfusion.  A few small studies have described the use of allogenic bone marrow or stem cell transplantation for hereditary and congenital forms of sideroblastic anemia. While these therapies may offer the possibility of a cure, the complications associated with transplantation surgery must be considered.  All patients with sideroblastic anemia should be followed by a hematologist and avoid alcohol.
Leiomyosarcoma is a rare cancerous tumor that consists of smooth (involuntary) muscle cells. Leiomyosarcoma is a type of sarcoma. It spreads through the blood stream and can affect the lungs, liver, blood vessels, or any other soft tissue in the body. The exact cause of leiomyosarcoma is not known, although genetic and environmental factors appear to be involved. It is most often found in the uterus or abdomen.
How might leiomyosarcoma be treated? Treatment of leiomyosarcoma varies depending on the location and stage of the cancer. Surgery is typically the first choice for treatment, however, chemotherapy, targeted drugs, radiation therapy, and hormonal therapy may also be used to treat leiomyosarcoma. Additional information on the treatment of intestinal leiomyosarcoma is available from Medscape Reference. You may need to register to view this online medical resource, but registration is free
What treatments are available for ovarian small cell carcinoma? Ovarian small cell carcinoma is often treated with surgery and chemotherapy. Radiation therapy may also be used in some cases. Because this tumor is derived from the primitive germ cells (eggs) of the ovary, it is often treated with a chemotherapy regimen similar to what is used to treat ovarian germ cell tumors. Specifically, platinum and etoposide based chemotherapy is typically used to treat ovarian small cell carcinoma.
Osteochondritis dissecans is a joint condition that occurs when a piece of cartilage and the thin layer of bone beneath it, separates from the end of the bone. If the piece of cartilage and bone remain close to where they detached, they may not cause any symptoms. However, affected people may experience pain, weakness and/or decreased range of motion in the affected joint if the cartilage and bone travel into the joint space. Although osteochondritis dissecans can affect people of all ages, it is most commonly diagnosed in people between the ages of 10 and 20 years. In most cases, the exact underlying cause is unknown. Rarely, the condition can affect more than one family member (called familial osteochondritis dissecans); in these cases, osteochondritis dissecans is caused by changes (mutations) in the ACAN gene and is inherited in an autosomal dominant manner. Treatment for the condition varies depending on many factors, including the age of the affected person and the severity of the symptoms, but may include rest; casting or splinting; surgery and/or physical therapy.
What are the signs and symptoms of Familial osteochondritis dissecans? The signs and symptoms of osteochondritis dissecans vary from person to person. If the piece of cartilage and bone remain close to where they detached, they may not cause any symptoms. However, affected people may experience the following if the cartilage and bone travel into the joint space: Pain, swelling and/or tenderness Joint popping Joint weakness Decreased range of motion Although osteochondritis dissecans can develop in any joint of the body, the knee, ankle and elbow are most commonly affected. Most people only develop the condition in a single joint. The Human Phenotype Ontology provides the following list of signs and symptoms for Familial osteochondritis dissecans. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes osteochondritis dissecans? In most cases, the exact underlying cause of osteochondritis dissecans is not completely understood. Scientists suspect that it may be due to decreased blood flow to the end of the affected bone, which may occur when repetitive episodes of minor injury and/or stress damage a bone overtime. In some families, osteochondritis dissecans is caused by changes (mutations) in the ACAN gene. In these cases, which are referred to as familial osteochondritis dissecans, the condition generally affects multiple joints and is also associated with short stature and early-onset osteoarthritis. The ACAN gene encodes a protein that is important to the structure of cartilage. Mutations in this gene weaken cartilage, which leads to the various signs and symptoms of familial osteochondritis disssecans.
How might osteochondritis dissecans be treated? The primary aim of treatment for osteochondritis dissecans is to restore normal function of the affected joint, relieve pain and prevent osteoarthritis. Treatment for the condition varies depending on many factors including the age of the affected person and the severity of the symptoms. In children and young teens, osteochondritis dissecans often heals overtime without surgical treatment. These cases are often managed with rest and in some cases, crutches and/or splinting to relieve pain and swelling. If non-surgical treatments are not successful or the case is particularly severe (i.e. the cartilage and bone are moving around within the joint space), surgery may be recommended. Following surgery, physical therapy is often necessary to improve the strength and range of motion of the affected joint.
Crohn's disease is a type of inflammatory bowel disease (IBD), the general name for conditions that cause inflammation in the gastrointestinal (GI) tract. Common signs and symptoms include abdominal pain and cramping, diarrhea, and weight loss. Other general symptoms include feeling tired, nausea and loss of appetite, fever, and anemia. Complications of Crohn's disease may include intestinal blockage, fistulas, anal fissures, ulcers, malnutrition, and inflammation in other areas of the body. Crohn's disease can occur in people of all age groups but is most often diagnosed in young adults. The exact cause is unknown, but is thought to involve both genetic and environmental factors. It appears to run in some families. Treatment is aimed at relieving symptoms and reducing inflammation, but some people require surgery.

Glutathione synthetase deficiency is type of organic acidemia that affects the production glutathione. Glutathione helps prevent cell damage, build DNA and proteins, and process medications and cancer-causing compounds. People can have mild, moderate, or severe disease. Mild disease may cause hemolytic anemia and 5-oxoprolinuria (excess excretion of 5-oxoproline in urine). Moderate disease may cause anemia, 5-oxoprolinuria, and metabolic acidosis in early infancy. Severe disease may cause anemia, 5-oxoprolinuria, metabolic acidosis, neurological symptoms (e.g., seizures, learning disability, loss of coordination), and recurrent infections. It is caused by mutations in the GSS gene and is inherited in an autosomal recessive fashion.
