What are the signs and symptoms of Currarino triad? The Human Phenotype Ontology provides the following list of signs and symptoms for Currarino triad. 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) Aplasia/Hypoplasia of the sacrum 90% Presacral teratoma 90% Hemisacrum (S2-S5) 75% Bifid sacrum 22% Arteriovenous malformation 7.5% Bifid scrotum 7.5% Displacement of the external urethral meatus 7.5% Hypoplasia of penis 7.5% Lower limb asymmetry 7.5% Male pseudohermaphroditism 7.5% Abdominal distention - Anal atresia - Anal fistula - Anal stenosis - Anterior sacral meningocele - Autosomal dominant inheritance - Bicornuate uterus - Chronic constipation - Gastrointestinal obstruction - Horseshoe kidney - Incomplete penetrance - Neurogenic bladder - Perianal abscess - Rectovaginal fistula - Recurrent urinary tract infections - Septate vagina - Tethered cord - Urinary incontinence - Vesicoureteral reflux - 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 causes Currarino triad ? 

What causes Currarino triad? Currarino triad is caused by mutations in the MNX1 gene in nearly all familial and 30% of sporadic cases. These mutations in the gene are called loss of function mutations because the gene can no longer produce working (functional) protein. Less frequently, a complex phenotype of Currarino triad can be caused by microdeletions of 7q containing MNX1 (the long arm of chromosome 7 is missing a small piece of DNA which includes MNX1 and other genes).
Is Currarino triad inherited ? 

How is Currarino triad inherited? Currarino triad is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one copy of the MNX1 gene in each cell is enough to cause features of the condition. In some cases, an affected person inherits the mutated gene from an affected parent. In other cases, the mutation occurs for the first time in a person with no family history of the condition. This is called a de novo mutation. When a person with a mutation that causes an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit that mutation. A significant interfamilial (between different families) and intrafamilial (within the same family) variability in expression has been found without any definite correlation to the genetic mutations. This means in one family, a parent might only have one very mild feature of Currarino triad while one of their children might have severe forms of all three features and yet another child might have a mild form of one feature and a severe form of another.

What is (are) Tracheobronchomalacia ? 

Tracheobronchomalacia (TBM) is a rare condition that occurs when the walls of the airway (specifically the trachea and bronchi) are weak. This can cause the airway to become narrow or collapse. There are two forms of TBM: a congenital form (called primary TBM) that typically develops during infancy or early childhood and an acquired form (called secondary TBM) that is usually seen in adults. Some affected people may initially have no signs or symptoms. However, the condition is typically progressive (becomes worse overtime) and most people will eventually develop characteristic features such as shortness of breath, cough, sputum retention (inability to clear mucus from the respiratory tract), and wheezing or stridor with breathing. Most cases of primary TBM are caused by genetic conditions that weaken the walls of the airway, while the secondary form often occurs incidentally due to trauma, chronic inflammation and/or prolonged compression of the airways. Treatment is generally only required in those who have signs and symptoms of the condition and may include stenting, surgical correction, continuous positive airway pressure (CPAP), and tracheostomy.

Primary TBM (also called congenital TBM) typically develops during infancy or early childhood, while secondary TBM (also called acquired TBM) is usually seen in adults. Some affected people may initially have no signs or symptoms. However, the condition is typically progressive (becomes worse overtime) and many people will eventually develop characteristic features such as shortness of breath, cough, sputum retention (inability to clear mucus from the respiratory tract), and wheezing or stridor with breathing. Symptoms may become worse during periods of stress (i.e. illness), when reclining, or when forcing a cough. Infants and young children with TBM tend to have more frequent respiratory infections and delayed recovery from these illnesses.
What causes Tracheobronchomalacia ? 

What causes tracheobronchomalacia? The underlying cause of tracheobronchomalacia (TBM) varies by subtype. Most cases of primary TBM (also called congenital TBM) are caused by genetic conditions that weaken the walls of the airway (specifically the trachea and bronchi). For example, TBM has been reported in people with mucopolysaccharidoses (such as Hunter syndrome and Hurler syndrome), Ehlers-Danlos Syndrome, and a variety of chromosome abnormalities. Primary TBM can also be idiopathic (unknown cause) or associated with prematurity and certain birth defects (i.e. tracheoesophageal fistula). The secondary form (also called acquired TBM) is caused by the degeneration (break down) of cartilage that typically supports the airways. It is most commonly associated with: Certain medical procedures such as endotracheal intubation or tracheostomy Conditions that lead to chronic (persisting or progressing for a long period of time) inflammation such as relapsing polychondritis or chronic obstructive pulmonary disease (COPD) Cancers, tumors, or cysts that cause prolonged compression of the airway
Is Tracheobronchomalacia inherited ? 

Is tracheobronchomalacia inherited? Primary tracheobronchomalacia (TBM) is often associated with certain genetic conditions. In some cases, an affected person inherits the condition from an affected parent. Other cases may result from new (de novo) gene mutations. These cases occur in people with no history of the disorder in their family. When TBM is part of a genetic condition, it can be passed on to future generations. Secondary TBM (also called acquired TBM) is not inherited. It generally occurs incidentally due to trauma, chronic inflammation and/or prolonged compression of the airways.
How to diagnose Tracheobronchomalacia ? 

How is tracheobronchomalacia diagnosed? A diagnosis of tracheobronchomalacia (TBM) may be suspected based on the presence of characteristic signs and symptoms or abnormal pulmonary function tests. Additional testing such as CT scan and bronchoscopy can then be performed to confirm the diagnosis and evaluate the severity of the condition. TBM is considered mild if the trachea narrows to 50% of its initial size while the affected person is breathing out, moderate if it narrows to 25%, and severe if the walls of the trachea touch.
What are the treatments for Tracheobronchomalacia ? 

How might tracheobronchomalacia be treated? Treatment is only medically necessary in people who have signs and symptoms of tracheobronchomalacia (TBM). Management of symptomatic TBM first involves identifying underlying conditions contributing to symptoms, such as chronic inflammation, compression, or injury. Initial treatment will target these underlying medical concerns. If symptoms persist, people with TBM may undergo pulmonary function tests or other assessments to help guide therapy choice and allow monitoring of the response to treatment. Treatment options may include: Silicone and/or long-term stenting Surgical correction Continuous positive airway pressure (CPAP) Tracheostomy (often used as a last resort as it can sometimes worsen TBM) We strongly recommend that you discuss your treatment options with a healthcare provider.

What is (are) Amelogenesis imperfecta ? 

Amelogenesis imperfecta (AI) (amelogenesis - enamel formation; imperfecta - imperfect) is a disorder that affects the structure and appearance of the enamel of the teeth. This condition causes teeth to be unusually small, discolored, pitted or grooved, and prone to rapid wear and breakage. These dental problems, which vary among affected individuals, can affect both primary (baby) teeth and permanent teeth. There are 4 main types of AI that are classified based on the type of enamel defect. These 4 types are divided further into 14 subtypes, which are distinguished by their specific dental abnormalities and by their pattern of inheritance. AI can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive pattern.
What are the symptoms of Amelogenesis imperfecta ? 

What are the signs and symptoms of amelogenesis imperfecta? In general, the both primary and permanent teeth are affected. The enamel tends to be soft and weak, and the teeth appear yellow and damage easily. The defects associated with amelogeneis imperfecta are highly variable and include abnormalities classified as hypoplastic (defects in the amount of enamel), hypomaturation (defect in the final growth and development of the tooth enamel), and hypocalcification (defect in the initial stage of enamel formation followed by defective tooth growth). The enamel in the hypomaturation and hypocalcification types is not mineralized and is thus described as hypomineralized. Traditionally, the diagnosis and classification of amelogenesis imperfecta is based on the clinical presentation and the mode of inheritance. There are four principal types based on the defects in the tooth enamel. These types are subdivided into 14 different subtypes based on the clinical presentation and the mode of inheritance. Detailed information about the signs and symptoms associated with the four major types of amelogenesis imperfecta is available from the UNC School of Dentistry.
What causes Amelogenesis imperfecta ? 

What causes amelogenesis imperfecta? Amelogenesis imperfecta is caused by mutations in the AMELX, ENAM, and MMP20 genes. These genes provide instructions for making proteins that are essential for normal tooth development. These proteins are involved in the formation of enamel, which is the hard, calcium-rich material that forms the protective outer layer of each tooth. Mutations in any of these genes alter the structure of these proteins or prevent the genes from making any protein at all. As a result, tooth enamel is abnormally thin or soft and may have a yellow or brown color. Teeth with defective enamel are weak and easily damaged. In some cases, the genetic cause of amelogenesis imperfecta can not been identified. Researchers are working to find mutations in other genes that are responsible for this disorder. Click on each gene name to learn more about the role it plays in the development of tooth enamel.
Is Amelogenesis imperfecta inherited ? 

How is amelogenesis imperfecta inherited? Amelogenesis imperfecta can have different patterns of inheritance, depending on the gene that is altered. Most cases are caused by mutations in the ENAM gene and are inherited in an autosomal dominant pattern. This type of inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Amelogenesis imperfecta may also be inherited in an autosomal recessive pattern; this form of the disorder can result from mutations in the ENAM or MMP20 gene. Autosomal recessive inheritance means two copies of the gene in each cell are altered. About 5 percent of amelogenesis imperfecta cases are caused by mutations in the AMELX gene and are inherited in an X-linked pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. In most cases, males with X-linked amelogenesis imperfecta experience more severe dental abnormalities than females with this form of this condition. Other cases of amelogenesis imperfecta result from new mutations in these genes and occur in people with no history of the disorder in their family.
How to diagnose Amelogenesis imperfecta ? 

How is amelogenesis imperfecta diagnosed? A dentist can identify and diagnose amelogenesis imperfecta on the basis of the patient's family history and the signs and symptoms present in the affected individual. Extraoral X-rays (X-rays taken outside the mouth) can reveal the presence of teeth that never erupted o that were absorbed. Intraoral X-rays (X-rays taken inside the mouth) show contrast between the enamel and dentin in cases in which mineralization is affected. Genetic testing is available for the genes AMELX, ENAM, and MMP20. You can visit the Genetic Testing Registry to locate laboratories performing genetic testing for these genes. The American Academy of Pediatric Dentistry is a source of information to find a pediatric dentist. The National Dental Association can also assist people in locating a dentist.
