Question: What are the genetic changes related to Loeys-Dietz syndrome ?

Answer: The four types of Loeys-Dietz syndrome are distinguished by their genetic cause: mutations in the TGFBR1 gene cause type I, mutations in the TGFBR2 gene cause type II, mutations in the SMAD3 gene cause type III, and mutations in the TGFB2 gene cause type IV. These four genes play a role in cell signaling that promotes growth and development of the body's tissues. This signaling pathway also helps with bone and blood vessel development and plays a part in the formation of the extracellular matrix, an intricate lattice of proteins and other molecules that forms in the spaces between cells.  Mutations in the TGFBR1, TGFBR2, TGFB2, and SMAD3 genes result in the production of proteins with little or no function. Even though these proteins have severely reduced function, cell signaling occurs at an even greater intensity than normal. Researchers speculate that the activity of proteins in this signaling pathway is increased to compensate for the protein whose function is reduced; however, the exact mechanism responsible for the increase in signaling is unclear. The overactive signaling pathway disrupts the development of connective tissue, the extracellular matrix, and various body systems, leading to the varied signs and symptoms of Loeys-Dietz syndrome.
Question: What is (are) spastic paraplegia type 31 ?

Answer: Spastic paraplegia type 31 is one of a group of genetic disorders known as hereditary spastic paraplegias. These disorders are characterized by progressive muscle stiffness (spasticity) and the development of paralysis of the lower limbs (paraplegia) caused by degeneration of nerve cells (neurons) that trigger muscle movement. Hereditary spastic paraplegias are divided into two types: pure and complicated. The pure types involve only the lower limbs, while the complicated types also involve the upper limbs and other areas of the body, including the brain. Spastic paraplegia type 31 is usually a pure hereditary spastic paraplegia, although a few complicated cases have been reported.  The first signs and symptoms of spastic paraplegia type 31 usually appear before age 20 or after age 30. An early feature is difficulty walking due to spasticity and weakness, which typically affect both legs equally. People with spastic paraplegia type 31 can also experience progressive muscle wasting (amyotrophy) in the lower limbs, exaggerated reflexes (hyperreflexia), a decreased ability to feel vibrations, reduced bladder control, and high-arched feet (pes cavus). As the condition progresses, some individuals require walking support.
Question: What is (are) Parkinson disease ?

Answer: Parkinson disease is a progressive disorder of the nervous system. The disorder affects several regions of the brain, especially an area called the substantia nigra that controls balance and movement.  Often the first symptom of Parkinson disease is trembling or shaking (tremor) of a limb, especially when the body is at rest. Typically, the tremor begins on one side of the body, usually in one hand. Tremors can also affect the arms, legs, feet, and face. Other characteristic symptoms of Parkinson disease include rigidity or stiffness of the limbs and torso, slow movement (bradykinesia) or an inability to move (akinesia), and impaired balance and coordination (postural instability). These symptoms worsen slowly over time.  Parkinson disease can also affect emotions and thinking ability (cognition). Some affected individuals develop psychiatric conditions such as depression and visual hallucinations. People with Parkinson disease also have an increased risk of developing dementia, which is a decline in intellectual functions including judgment and memory.  Generally, Parkinson disease that begins after age 50 is called late-onset disease. The condition is described as early-onset disease if signs and symptoms begin before age 50. Early-onset cases that begin before age 20 are sometimes referred to as juvenile-onset Parkinson disease.
Question: What are the genetic changes related to hereditary myopathy with early respiratory failure ?

Answer: HMERF can be caused by a mutation in the TTN gene. This gene provides instructions for making a protein called titin. Titin plays an important role in muscles the body uses for movement (skeletal muscles) and in heart (cardiac) muscle.  Within muscle cells, titin is an essential component of structures called sarcomeres. Sarcomeres are the basic units of muscle contraction; they are made of proteins that generate the mechanical force needed for muscles to contract. Titin has several functions within sarcomeres. One of its most important jobs is to provide structure, flexibility, and stability to these cell structures. Titin also plays a role in chemical signaling and in assembling new sarcomeres.  The TTN gene mutation responsible for HMERF leads to the production of an altered version of the titin protein. Studies suggest that this change may disrupt titin's interactions with other proteins within sarcomeres and interfere with the protein's role in chemical signaling. Consequently, muscle fibers become damaged and weaken over time. It is unclear why these effects are usually limited to proximal muscles and muscles involved in breathing.  Some people with the characteristic features of HMERF do not have identified mutations in the TTN gene. In these cases, the genetic cause of the condition is unknown.
Question: Is thiopurine S-methyltransferase deficiency inherited ?

Answer: The activity of the TPMT enzyme is inherited in a pattern described as autosomal codominant. Codominance means that two different versions of the gene are active (expressed), and both versions influence the genetic trait.  The TPMT gene can be classified as either low-activity or high-activity. When the gene is altered in a way that impairs the activity of the TPMT enzyme, it is described as low-activity. When the gene is unaltered and TPMT activity is normal, it is described as high-activity. Because two copies of the gene are present in each cell, each person can have two low-activity copies, one low-activity copy and one high-activity copy, or two high-activity copies.  People with two low-activity copies of the TPMT gene in each cell have TPMT deficiency and are at the greatest risk of developing hematopoietic toxicity when treated with thiopurine drugs unless they are given much less than the usual dose. People with one high-activity copy and one low-activity copy have moderately reduced enzyme activity and are also at increased risk of this complication unless given a significantly lower dose of the drug. People with two high-activity copies have normal TPMT activity and do not have an increased risk of hematopoietic toxicity with thiopurine drug treatment.

Question: What are the symptoms of What I need to know about Hirschsprung Disease ?

Answer: The main symptoms of HD are constipation or intestinal obstruction, usually appearing shortly after birth. Constipation in infants and children is common and usually comes and goes, but if your child has had ongoing constipation since birth, HD may be the problem.
                
Symptoms in Newborns
                
Newborns with HD almost always fail to have their first bowel movement within 48 hours after birth. Other symptoms include
                
- green or brown vomit  - explosive stools after a doctor inserts a finger into the rectum  - swelling of the belly, also known as the abdomen  - lots of gas  - bloody diarrhea
                

                
Symptoms in Toddlers and Older Children
                
Symptoms of HD in toddlers and older children include
                
- not being able to pass stools without laxatives or enemas. A laxative is medicine that loosens stool and increases bowel movements. An enema is performed by flushing water, or sometimes a mild soap solution, into the anus using a special wash bottle.  - swelling of the abdomen.  - lots of gas.  - bloody diarrhea.  - slow growth or development.  - lack of energy because of a shortage of red blood cells, called anemia.
Question: What is (are) Respiratory Failure ?

Answer: Respiratory failure happens when not enough oxygen passes from your lungs into your blood. Your body's organs, such as your heart and brain, need oxygen-rich blood to work well. Respiratory failure also can happen if your lungs can't remove carbon dioxide (a waste gas) from your blood. Too much carbon dioxide in your blood can harm your body's organs.    Diseases and conditions that affect your breathing can cause respiratory failure. Examples include       - Lung diseases such as COPD (chronic obstructive pulmonary disease), pneumonia, pulmonary embolism, and cystic fibrosis    - Conditions that affect the nerves and muscles that control breathing, such as spinal cord injuries, muscular dystrophy and stroke    - Damage to the tissues and ribs around the lungs. An injury to the chest can cause this damage.    - Drug or alcohol overdose    - Injuries from inhaling smoke or harmful fumes       Treatment for respiratory failure depends on whether the condition is acute (short-term) or chronic (ongoing) and how severe it is. It also depends on the underlying cause. You may receive oxygen therapy and other treatment to help you breathe.    NIH: National Heart, Lung, and Blood Institute
Question: What is (are) Myasthenia Gravis ?

Answer: Myasthenia gravis is disease that causes weakness in the muscles under your control. It happens because of a problem in communication between your nerves and muscles. Myasthenia gravis is an autoimmune disease. Your body's own immune system makes antibodies that block or change some of the nerve signals to your muscles. This makes your muscles weaker.    Common symptoms are trouble with eye and eyelid movement, facial expression and swallowing. But it can also affect other muscles. The weakness gets worse with activity, and better with rest.    There are medicines to help improve nerve-to-muscle messages and make muscles stronger. With treatment, the muscle weakness often gets much better. Other drugs keep your body from making so many abnormal antibodies. There are also treatments which filter abnormal antibodies from the blood or add healthy antibodies from donated blood. Sometimes surgery to take out the thymus gland helps.    For some people, myasthenia gravis can go into remission and they do not need medicines. The remission can be temporary or permanent.    If you have myasthenia gravis, it is important to follow your treatment plan. If you do, you can expect your life to be normal or close to it.

Question: What is (are) Patulous Eustachian Tube ?

Answer: Patulous eustachian tube is a benign condition in which the eustachian tube stays open most of the time. The eustachian tube is the tube that runs between the middle ear and throat and regulates the ear pressure around the ear drum. Under normal circumstances, it remains closed most of the time, opening only on occasion to equalize air pressure between the middle ear and the exterior environment. Major symptoms include distorted autophony (hearing one's own voice or breathing), echoing which may interfere with speech production, wave-like sounds, and a sensation of fullness in the ear. In severe cases, vertigo and hearing loss may occur. Over time, individuals with patulous eustachian tube may develop serious and even extreme responses to the abnormal sounds and other findings. In most cases, the cause of patulous eustachian tube is unknown. Weight loss and pregnancy may be predisposing factors. Neurologic disorders that cause muscle atrophy such as stroke, multiple sclerosis, and motor neuron disease have been implicated in some cases of patulous eustachian tube. Other cases may be associated with medications such as oral contraceptives or diuretics. Other predisposing factors include fatigue, stress, anxiety, exercise, and temporomandibular joint syndrome.

Question: Is Multiple epiphyseal dysplasia inherited ?

Answer: How is multiple epiphyseal dysplasia inherited? Multiple epiphyseal dysplasia (MED) may be inherited in an autosomal dominant or autosomal recessive manner depending on the genetic cause. Most cases are autosomal dominant. In autosomal dominant inheritance, having a mutation in only one of the 2 copies of the responsible gene is enough to cause the condition. The mutation may be inherited from a parent or can occur for the first time in the affected person. Each child of a person with an autosomal dominant condition has a 50% (1 in 2) chance to inherit the mutation. More rarely, MED is inherited in an autosomal recessive manner. In autosomal recessive inheritance, a person must have a mutation in both copies of the responsible gene to be affected. The parents of a person with an autosomal recessive condition usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not have signs or symptoms and are unaffected. When two carriers for the same condition have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% to be both unaffected and not a carrier.
Question: Is Von Hippel-Lindau disease inherited ?

Answer: How is von Hippel-Lindau (VHL) disease inherited? Mutations in the gene that causes VHL disease (the VHL gene) are inherited in an autosomal dominant manner. This means that having a mutation in only one copy of the VHL gene in each cell is enough to increase a person's risk of developing VHL disease. In most autosomal dominant conditions, having one mutated copy of the responsible gene is sufficient to cause the condition. However, in VHL disease, a mutation in the other copy of the gene must occur (during a person's lifetime) to trigger the development of VHL disease. For example, a person may inherit a mutated copy of the gene from a parent, but acquiring a second mutation in the other gene copy in a specific organ may trigger tumor development in that organ. Almost everyone who is born with one VHL mutation will eventually acquire a mutation in the second copy of the gene and develop VHL disease. In most cases, an affected person inherits the first mutated gene from an affected parent. However, in about 20% of 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 can lead to VHL disease has children, each of their children has a 50% (1 in 2) chance to inherit that mutation.
Question: What is (are) Urachal cancer ?

Answer: Urachal cancer is a rare type of bladder cancer, making up less than 1% of all bladder cancers. Only about 350 cases have been described in the medical literature to date. The urachus is a primitive structure which before birth connected the bellybutton and the bladder. This connection normally disappears before birth, but in some people remains.  Urachal cancers are classified as such based on location at the dome or anterior wall of the bladder and discovery of remnants of the urachus. Most urachal cancers are adenocarcinomas (cancers that develop from gland cells). Others may be sarcomas (which develop from connective tissue - such as leiomyosarcoma, rhabdomyosarcoma, and malignant fibrous histiocytoma), small cell carcinomas, transitional cell cancer, and mixed neoplasias. Most individuals with urachal cancer present with hematuria (blood in urine). Other symptoms may include abdominal pain, a palpable abdominal mass, mucinuria, and bacteriuria. Patients who present with early disease confined to the urachus have a good prognosis when treated with partial cystectomy, umbilicotomy, and urachal resection. The prognosis for those with advanced disease is less promising.
