Question: What are the symptoms of Kuskokwim disease ?

Answer: What are the signs and symptoms of Kuskokwim disease? The range and and severity of signs and symptoms in individuals with Kuskokwim disease can vary, even among siblings. Affected individuals usually have congenital contractures, especially of lower extremities, which progress during childhood and persist for the lifetime of the individual. However, not all individuals with the condition have contractures at birth. The severity of contractures can be very asymmetrical in any given individual. The knees and elbows are often affected, and skeletal abnormalities of the spine, pelvis, and feet also commonly occur. Muscle atrophy of limbs with contractures and displacement of kneecaps (patellae) have also been reported. Milder skeletal features are common. Vertebral features may include spondylolisthesis, mild to moderate scoliosis, and/or lordosis. Many affected individuals have had several low-energy fractures. Other skeletal abnormalities that have been reported include bunions (hallux valgus), "flat feet" (plano valgus feet), and clubfoot (talipes equinovarus). Development and arrangement of the teeth (dentition) are normal. Although some individuals with full bilateral contractures of the knees can move about by duck walking (sitting with buttocks on their heels) or by knee walking (moving on their knees with their lower legs drawn up behind them to their buttocks), most affected individuals are treated with leg braces and/or surgery in childhood and can walk upright. The Human Phenotype Ontology provides the following list of signs and symptoms for Kuskokwim disease. 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) Gait disturbance 90% Limitation of joint mobility 90% Patellar aplasia 90% Talipes 50% Abnormal form of the vertebral bodies 7.5% Abnormality of the clavicle 7.5% Aplasia/Hypoplasia of the radius 7.5% Melanocytic nevus 7.5% Scoliosis 7.5% Autosomal recessive inheritance - Skeletal muscle atrophy - 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.
Question: What is (are) Congenital Myopathy ?

Answer: A myopathy is a disorder of the muscles that usually results in weakness. Congenital myopathy refers to a group of muscle disorders that appear at birth or in infancy. Typically, an infant with a congenital myopathy will be "floppy," have difficulty breathing or feeding, and will lag behind other babies in meeting normal developmental milestones such as turning over or sitting up.
                
Muscle weakness can occur for many reasons, including a problem with the muscle, a problem with the nerve that stimulates the muscle, or a problem with the brain. Therefore, to diagnose a congenital myopathy, a neurologist will perform a detailed physical exam as well as tests to determine the cause of weakness. If a myopathy is suspected, possible tests include a blood test for a muscle enzyme called creatine kinase, an electromyogram (EMG) to evaluate the electrical activity of the muscle, a muscle biopsy, and genetic testing.
                
There are currently seven distinct types of congenital myopathy, with some variation in symptoms, complications, treatment options, and outlook.
                
Nemaline myopathy is the most common congenital myopathy. Infants usually have problems with breathing and feeding. Later, some skeletal problems may arise, such as scoliosis (curvature of the spine). In general, the weakness does not worsen during life.
                
Myotubular myopathy is rare and only affects boys. Weakness and floppiness are so severe that a mother may notice reduced movements of the baby in her womb during pregnancy. There are usually significant breathing and swallowing difficulties; many children do not survive infancy. Osteopenia (weakening of the bones) is also associated with this disorder.
                
Centronuclear myopathy is rare and begins in infancy or early childhood with weakness of the arms and legs, droopy eyelids, and problems with eye movements. Weakness often gets worse with time.
                
Central core disease varies among children with regard to the severity of problems and the degree of worsening over time. Usually, there is mild floppiness in infancy, delayed milestones, and moderate limb weakness, which do not worsen much over time. Children with central core disease may have life-threatening reactions to general anesthesia. Treatment with the drug salbutamol has been shown to reduce weakness significantly, although it does not cure the disorder.
                
Multi-minicore disease has several different subtypes. Common to most is severe weakness of the limbs and scoliosis. Often breathing difficulties occur as well. Some children have weakened eye movements.
                
Congenital fiber-type disproportion myopathy is a rare disorder that begins with floppiness, limb and facial weakness, and breathing problems.
                
Hyaline body myopathy is a disorder characterized by the specific appearance under the microscope of a sample of muscle tissue. It probably includes several different causes. Because of this, the symptoms are quite variable.
Question: What are the genetic changes related to SLC4A1-associated distal renal tubular acidosis ?

Answer: Both the autosomal dominant and autosomal recessive forms of SLC4A1-associated distal renal tubular acidosis are caused by mutations in the SLC4A1 gene. This gene provides instructions for making the anion exchanger 1 (AE1) protein, which transports negatively charged atoms (anions) across cell membranes. Specifically, AE1 exchanges negatively charged atoms of chlorine (chloride ions) for negatively charged bicarbonate molecules (bicarbonate ions). The AE1 protein is found in the cell membrane of kidney cells and red blood cells. In kidney cells, the exchange of bicarbonate through AE1 allows acid to be released from the cell into the urine. In red blood cells, AE1 attaches to other proteins that make up the structural framework (the cytoskeleton) of the cells, helping to maintain their structure.  The SLC4A1 gene mutations involved in either form of SLC4A1-associated distal renal tubular acidosis lead to production of altered AE1 proteins that cannot get to the correct location in the cell membrane. In the autosomal dominant form of the condition, gene mutations affect only one copy of the SLC4A1 gene, and normal AE1 protein is produced from the other copy. However, the altered protein attaches to the normal protein and keeps it from getting to the correct location, leading to a severe reduction or absence of AE1 protein in the cell membrane. In autosomal recessive distal renal tubular acidosis, both copies of the SLC4A1 gene are mutated, so all of the protein produced from this gene is altered and not able to get to the correct location. Improper location or absence of AE1 in kidney cell membranes disrupts bicarbonate exchange, and as a result, acid cannot be released into the urine. Instead, the acid builds up in the blood in most affected individuals, leading to metabolic acidosis and the other features of complete distal renal tubular acidosis. It is not clear why some people develop metabolic acidosis and others do not. Researchers suggest that in individuals with incomplete distal renal tubular acidosis, another mechanism is able to help regulate blood acidity (pH) and keep metabolic acidosis from developing.  In red blood cells, interaction with a protein called glycophorin A can often help the altered AE1 protein get to the cell membrane where it can perform its function, which explains why most people with SLC4A1-associated distal renal tubular acidosis do not have blood cell abnormalities. However, some altered AE1 proteins cannot be helped by glycophorin A and are not found in the cell membrane. Without AE1, the red blood cells are unstable; breakdown of these abnormal red blood cells may lead to hemolytic anemia.  Some people have nonhereditary forms of distal renal tubular acidosis; these forms can be caused by immune system problems or other conditions that damage the kidneys. These individuals often have additional signs and symptoms related to the original condition.

Question: What is (are) caudal regression syndrome ?

Answer: Caudal regression syndrome is a disorder that impairs the development of the lower (caudal) half of the body. Affected areas can include the lower back and limbs, the genitourinary tract, and the gastrointestinal tract.  In this disorder, the bones of the lower spine (vertebrae) are frequently misshapen or missing, and the corresponding sections of the spinal cord are also irregular or missing. Affected individuals may have incomplete closure of the vertebrae around the spinal cord, a fluid-filled sac on the back covered by skin that may or may not contain part of the spinal cord, or tufts of hair at the base of the spine. People with caudal regression syndrome can also have an abnormal side-to-side curvature of the spine (scoliosis). The spinal abnormalities may affect the size and shape of the chest, leading to breathing problems in some individuals.  Individuals with caudal regression syndrome may have small hip bones with a limited range of motion. The buttocks tend to be flat and dimpled. The bones of the legs are typically underdeveloped, most frequently the upper leg bones (femurs). In some individuals, the legs are bent with the knees pointing out to the side and the feet tucked underneath the hips (sometimes called a frog leg-like position). Affected individuals may be born with inward- and upward-turning feet (clubfeet), or the feet may be outward- and upward-turning (calcaneovalgus). Some people experience decreased sensation in their lower limbs.  Abnormalities in the genitourinary tract in caudal regression syndrome are extremely varied. Often the kidneys are malformed; defects include a missing kidney (unilateral renal agenesis), kidneys that are fused together (horseshoe kidney), or duplication of the tubes that carry urine from each kidney to the bladder (ureteral duplication). These kidney abnormalities can lead to frequent urinary tract infections and progressive kidney failure. Additionally, affected individuals may have protrusion of the bladder through an opening in the abdominal wall (bladder exstrophy). Damage to the nerves that control bladder function, a condition called neurogenic bladder, causes affected individuals to have progressive difficulty controlling the flow of urine. Genital abnormalities in males can include the urethra opening on the underside of the penis (hypospadia) or undescended testes (cryptorchidism). Females may have an abnormal connection between the rectum and vagina (rectovaginal fistula). In severe cases, both males and females have a lack of development of the genitalia (genital agenesis).  People with caudal regression syndrome may have abnormal twisting (malrotation) of the large intestine, an obstruction of the anal opening (imperforate anus), soft out-pouchings in the lower abdomen (inguinal hernias), or other malformations of the gastrointestinal tract. Affected individuals are often constipated and may experience loss of control of bladder and bowel function.

Question: What are the symptoms of Troyer syndrome ?

Answer: What are the signs and symptoms of Troyer syndrome? The signs and symptoms of Troyer syndrome can vary, and some people are more severely affected than others. Symptoms typically begin in early childhood. Most affected children have delays in walking and talking, followed by slow deterioration in both manner of walking (gait) and speech. Affected people have progressive muscle weakness and stiffness (spasticity) in the legs; muscle wasting in the hands and feet; paraplegia; leg contractures; learning disorders; and short stature. Mood swings and mood disorders, causing inappropriate euphoria and/or crying, are common. Other features can include drooling; exaggerated reflexes (hyperreflexia) in the legs; uncontrollable movements of the arms and legs (choreoathetosis); skeletal abnormalities; and a bending outward (valgus) of the knees. There is generally a slow, progressive decline in muscle and nerve function, and symptoms worsen over time. Most people need a wheelchair by their 50s or 60s. Affected people typically have a normal life expectancy. The Human Phenotype Ontology provides the following list of signs and symptoms for Troyer syndrome.
