How to diagnose Factor V Leiden thrombophilia ? 

How is factor V Leiden thrombophilia diagnosed? No clinical features (signs and/or symptoms) are specific for factor V Leiden thrombophilia. The diagnosis of factor V Leiden thrombophilia requires a coagulation screening test or DNA analysis of F5, the gene for factor V, to identify the specific mutation that causes this condition. The APC (activated protein C) resistance assay, a coagulation screening test, measures the anticoagulant response to APC. This screening test has a sensitivity and specificity for factor V Leiden approaching 100%. The sensitivity of a test is a measure of the test's ability to detect a positive result when someone has the condition, while the specificity is a measure of the test's ability to identify negative results.Targeted mutation analysis (a type of DNA test) of the F5 gene for the Leiden mutation is considered definitive and has a mutation detection frequency of approximately 100%. This means that approximately all individuals who have the factor V Leiden mutation will be detected by this genetic test. It is generally recommended that individuals who test positive by another means should then have the DNA test both for confirmation and to distinguish heterozygotes (individuals with a mutation in one copy of the gene) from homozygotes (individuals with mutations in both copies of the gene).
What are the treatments for Factor V Leiden thrombophilia ? 

How might factor V Leiden be treated? The management of individuals with factor V Leiden depends on the clinical circumstances. People with factor V Leiden who have had a deep venous thrombosis (DVT) or pulmonary embolism (PE) are usually treated with blood thinners, or anticoagulants. Anticoagulants such as heparin and warfarin are given for varying amounts of time depending on the person's situation. It is not usually recommended that people with factor V Leiden be treated lifelong with anticoagulants if they have had only one DVT or PE, unless there are additional risk factors present. Having had a DVT or PE in the past increases a person's risk for developing another one in the future, but having factor V Leiden does not seem to add to the risk of having a second clot. In general, individuals who have factor V Leiden but have never had a blood clot are not routinely treated with an anticoagulant. Rather, these individuals are counseled about reducing or eliminating other factors that may add to one's risk of developing a clot in the future. In addition, these individuals may require temporary treatment with an anticoagulant during periods of particularly high risk, such as major surgery. Factor V Leiden increases the risk of developing a DVT during pregnancy by about seven-fold. Women with factor V Leiden who are planning pregnancy should discuss this with their obstetrician and/or hematologist. Most women with factor V Leiden have normal pregnancies and only require close follow-up during pregnancy. For those with a history of DVT or PE, treatment with an anticoagulant during a subsequent pregnancy can prevent recurrent problems.

Signs and Symptoms Approximate number of patients (when available) Split hand 90% Abnormality of the tibia 50% Limitation of joint mobility 50% Abnormality of the femur 7.5% Abnormality of the fibula 7.5% Abnormality of the ulna 7.5% Brachydactyly syndrome 7.5% Finger syndactyly 7.5% Omphalocele 7.5% Overfolded helix 7.5% Patellar aplasia 7.5% Popliteal pterygium 7.5% Postaxial hand polydactyly 7.5% Preaxial hand polydactyly 7.5% Absent forearm - Absent tibia - Aplasia/Hypoplasia of the ulna - Autosomal dominant inheritance - Cupped ear - Monodactyly (hands) - Short hallux - Split foot - 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.
What is (are) Loeys-Dietz syndrome ? 

Loeys-Dietz syndrome is a connective tissue disorder that causes aortic aneurysms, widely spaced eyes (hypertelorism), cleft palate and/or split uvula (the little piece of flesh that hangs down in the back of the mouth) and twisting or spiraled arteries (arterial tortuosity). Other findings include craniosynostosis, extropia (eyes that turn outward), micrognathia, structural brain abnormalities, intellectual deficit, and congenital heart disease. Signs and symptoms vary among individuals. This condition is inherited in an autosomal dominant manner with variable clinical expression. This condition is called Loeys-Dietz syndrome type 1 when affected individuals have cleft palate, craniosynostosis, and/or hypertelorism. Individuals without these features are said to have Loeys-Dietz syndrome type 2. The disease is caused by mutations in the TGFBR1, the TGFBR2,  the SMAD3 or the TGFB2 genes. It is important to have an early and adequate treatment for the heart problems because the chance for aortic dissection and other vascular problems may be high in some patients. Many specialists may be involved for the best managment of the patient.

What is (are) Ovarian sex cord tumor with annular tubules ? 

An ovarian sex cord tumor with annular tubules (SCTAT) is a tumor that grows from cells in the ovaries known as sex cord cells.  As these cells grow, they form tube-like shapes in the tumor.  SCTATs can develop in one or both ovaries, and may cause symptoms such as puberty at an exceptionally young age (precocious puberty), irregular menstrual cycles, or post-menopausal bleeding.  Most ovarian SCTATs are benign. However, because there is a chance that an SCTAT may be malignant, treatment may include surgery to remove the tumor.
What causes Ovarian sex cord tumor with annular tubules ? 

What causes an ovarian sex cord tumor with annular tubules? Approximately one third of ovarian sex cord tumors with annual tubules (SCTATs) develop because of an underlying genetic condition called Peutz Jeghers syndrome (PJS), which is caused by a mutation in the STK11 gene.  In these genetic cases, many small SCTATs develop in both ovaries and are almost always benign.  The remaining two thirds of ovarian SCTATs are not related to a genetic condition and develop as a single tumor in one ovary; up to 25% of SCTATs in this group may be malignant.  Ovarian SCTATs not related to PJS have no known cause and are believed to occur by chance.

What is (are) Michels syndrome ? 

Michels syndrome is an extremely rare disorder characterized by the eyelid triad of blepharophimosis (a narrowing of the eye opening), blepharoptosis and epicanthus inversus (an upward fold of the skin of the lower eyelid near the inner corner of the eye), skeletal defects including craniosynostosis, cranial asymmetry, abnormality of the occipital bone (at the base of the skull), and radioulnar synostosis, cleft lip and palate, and mental deficiency. Only 10 cases have been reported in the medical literature. While the underlying cause of this condition remains unknown, it is believed to be transmitted as an autosomal recessive trait.  Based on phenotypic overlap and autosomal recessive inheritance, some researchers have suggested that Michels, Malpuech, Carnevale and Mingarelli syndromes represent a spectrum and should be referred to a 3MC syndrome (for Malpuech-Michels-Mingarelli-Carnevale).

What is (are) Chromosome 7q deletion ? 

Chromosome 7q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 7. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 7q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person.
What is (are) Membranous nephropathy ? 

Membranous nephropathy is a kidney disease characterized by inflammation of the structures inside the kidney that help filter wastes and fluids. When the glomerular basement membrane becomes thickened, it does not work normally, allowing large amounts of protein to be lost in the urine. Symptoms develop gradually and may include swelling, fatigue, weight gain, and high blood pressure. In many cases, the underlying cause of membranous nephropathy is not known. Some cases are associated with other conditions (lupus), infections (hepatitis B and C), cancer or as a side effect of certain medications. The goal of treatment is to reduce symptoms and slow the progression of the disease.

What is (are) Renal nutcracker syndrome ? 

Renal nutcracker syndrome (NCS) is a condition that occurs when the left renal vein (the vein that carries blood purified by the left kidney) becomes compressed. The signs and symptoms of the condition can vary from person to person. Some affected people may be asymptomatic while others develop severe and persistent symptoms. When present, features of NCS may include blood in the urine (hematuria), orthostatic proteinuria, flank pain and/or abdominal pain. Some cases of mild NCS in children may be due to changes in body proportions associated with growth. Why NCS occurs or becomes symptomatic in adults is less clear. Treatment ranges from surveillance to surgical intervention and is based on the severity of symptoms and their expected reversibility when considering the affected person's age and stage of the syndrome.
What are the symptoms of Renal nutcracker syndrome ? 

What are the signs and symptoms of renal nutcracker syndrome? The signs and symptoms of renal nutcracker syndrome and the disease severity can vary from person to person. Some affected people may be asymptomatic while others have severe and persistent symptoms. Symptoms are often aggravated by physical activity. When present, symptoms of the condition may include blood in the urine (hematuria), orthostatic proteinuria, flank pain and/or abdominal pain. Some people may also experience orthostatic intolerance, which is characterized by symptoms such as light-headedness, palpitations, poor concentration, fatigue, nausea, dizziness, headache, sweating, weakness and occasionally fainting when upright standing. Men who are affected by renal nutcracker syndrome may develop a varicocele. Affected women may have gynecological symptoms such as dyspareunia and dysmenorrhea (painful periods).
Is Renal nutcracker syndrome inherited ? 

Is renal nutcracker syndrome inherited? Renal nutcracker syndrome is not inherited. Most cases occur sporadically in people with no family history of the condition. Although more than one family member may rarely be affected, this is thought to be a coincidence and not the result of a genetic predisposition.
How to diagnose Renal nutcracker syndrome ? 

How is Renal nutcracker syndrome diagnosed? A diagnosis of renal nutcracker syndrome is often suspected based on the presence of characteristic signs and symptoms once other conditions that cause similar features have been ruled out. Additional testing can then be ordered to support the diagnosis. This may include urine tests, imaging studies of the kidneys (i.e. doppler ultrasonography, computed tomography angiography, magnetic resonance angiography, retrograde venography), and/or cystoscopy.
What are the treatments for Renal nutcracker syndrome ? 

How might renal nutcracker syndrome be treated? Treatment of renal nutcracker syndrome is based on severity of symptoms and their expected reversibility when considering the affected person's age and stage of the syndrome. Adults with mild cases and affected children may be treated conservatively with regular surveillance. People younger than 18 years, specifically, are often observed for at least 2 years because as many as 75% will have complete resolution of symptoms without any significant intervention. ACE inhibitors may be effective in treating orthostatic proteinuria. In those with severe symptoms who do not respond to more conservative treatments, surgery is often recommended.
