Distal arthrogryposis syndrome is a rare genetic disorder in which affected individuals are born with a characteristic bending at the joints of the hands and feet. A contracture is the word used to describe what happens at the joints to cause this bending. In addition to contractures of the hand and feet, individuals with distal arthrogryposis are born with a tightly clenched fist and overlapping fingers. The word arthrogryposis means a flexed bent or curved joint. Distal means the furthest from any one point of reference or something that is remote.

It usually follows a minor Guys wet pants incident and is associated with swelling, pain, and paradoxical stiffness. Very rarely, Inherited clinched fist syndrome piece of chromosome 18 becomes attached to another chromosome translocated before or after conception. The additional chromosome usually occurs before conception. Commonly searched drugs. From Wikipedia, the free encyclopedia. Surgery is usually needed when the Inherited clinched fist syndrome cannot be placed flat on a table, when the fingers curl so much that hand function is limited, or when multiple fingers are involved. Surgery to remove the diseased fascia is difficult because the fascia surrounds nerves, blood vessels, and tendons. Edwards syndrome occurs in around one in 5, live births. Ultrasoundamniocentesis .

Freeman-Sheldon syndrome is a rare inherited disorder characterized by multiple contractures i. Craniofacial abnormalities may consist of characteristic facial features that cause the individual to appear to be whistling. These features include an extremely small puckered mouth microstomia ; a "full" forehead appearance, unusually prominent cheeks; and thin, pursed lips.
Malformations of the hands and feet are also characteristic of Freeman-Sheldon syndrome. Freeman-Sheldon syndrome can be inherited as an autosomal dominant genetic trait.
Freeman-Sheldon syndrome is characterized by abnormalities of the head and face craniofacial area, defects of the hands and feet, and skeletal malformations. Symptoms and physical findings associated with this disorder are usually present at birth congenital and may vary greatly from case to case. Infants with Freeman-Sheldon syndrome exhibit various abnormalities of the head and face craniofacial area including an unusually small puckered mouth microstomia that appears as if the infants are attempting to whistle.
In addition, affected children may have a nasal quality to their voice nasal speech due to limited movement of the soft palate. In addition, swallowing and feeding difficulties may cause foreign material e. Several abnormalities of the eyes may be present in individuals with Freeman-Sheldon syndrome. In addition, the space between the upper and lower eyelids may be unusually narrow blepharophimosis. Other characteristic facial features associated with Freeman-Sheldon syndrome may include malformations of the nose.
The nose may be unusually small with narrow, underdeveloped nostrils nasi alae. In addition, the bridge of the nose may be abnormally broad and there may be an unusually long vertical gap between the upper lip philtrum and the nose. Several malformations affecting the hands and feet may be present in infants with Freeman-Sheldon syndrome.
Certain fingers may be permanently flexed camptodactyly outward away from the thumb ulnar deviation. In contrast, the thumbs may be flexed inward toward the palm adducted. Flexion of the fingers and thumbs may be caused by permanent fixation contracture of the joints between the fingers and the palms metacarpophalangeal joints. Infants with Freeman-Sheldon syndrome also exhibit deformities of the feet, including a form of club foot where the heel of the foot may be turned inward toward the body while the rest of the foot is bent downward and inward talipes equinovarus.
Club foot may cause walking difficulties. In some cases, degeneration atrophy of the muscles in the forearms and lower legs may also occur. In some cases, infants with Freeman-Sheldon syndrome experience delayed growth after birth postnatal growth deficiency.
Intelligence and cognition are typically unaffected in children with Freeman-Sheldon syndrome. In some cases, there may be slight delays in attaining motor milestones e. Additionally, some types of anesthesia administered to people with Freeman-Sheldon syndrome may trigger malignant hyperthermia which can be an acute life threatening condition.
It is therefore important for surgeons and dentists to be aware that certain types of anesthesia should be avoided in individuals with Freeman-Sheldon syndrome. Malignant hyperthermia is a disorder in which a person does not react appropriately to certain drugs due to a genetic abnormality. Affected individuals develop a rapid, high fever after the administration of general anesthesia or certain muscle relaxants.
Drugs that could cause this response include halothane, cyclopropane, or succinylcholine. People with Freeman-Sheldon Syndrome are especially prone to malignant hyperthermia. Other cases are inherited as an autosomal dominant trait. In rare cases, autosomal recessive or X-linked recessive inheritance has been suggested. Genetic diseases are determined by the combination of genes for a particular trait that are on the chromosomes received from the father and the mother.
Dominant genetic disorders occur when only a single copy of an abnormal gene is necessary for the appearance of the disease. The abnormal gene can be inherited from either parent, or can be the result of a new mutation gene change in the affected individual.
Investigators have determined that Freeman-Sheldon syndrome can be caused by disruptions or changes mutations to the embryonic myosin heavy chain MYH3 gene located on the short arm of chromosome 17 17p Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual.
Pairs of human chromosomes are numbered from 1 through 22, and an additional 23rd pair of sex chromosomes which include one X and one Y chromosome in males and two X chromosomes in females. Chromosomes are further sub-divided into many bands that are numbered. The numbered bands specify the location of the thousands of genes that are present on each chromosome. In some rare cases, a clinically indistinguishable form of Freeman-Sheldon syndrome is inherited as an autosomal recessive trait.
In a few of these cases, parents of several individuals with the disorder have been closely related by blood consanguineous. If both parents carry the same disease gene, then there is a higher than normal risk that their children may inherit the two disease genes for this disorder.
Recessive genetic disorders occur when an individual inherits the same abnormal gene for the same trait from each parent. If an individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms. The risk is the same for males and females. Freeman-Sheldon syndrome is a rare disorder that affects males and females in equal numbers.
Approximately cases have been reported in the medical literature since the disorder was first described in by Drs. Freeman and Sheldon. Some cases occurred within families kindreds over several generations.
Some symptoms and physical findings associated with the disorder are apparent at birth congenital. Freeman-Sheldon syndrome is one of a group of disorders that are associated with multiple congenital contractures MCCs. MCCs occur in approximately 1 in 3, children. Because the disorder shares features with other congenital contracture syndromes it sometimes is misdiagnosed making it difficult to determine its true frequency in the general population.
Symptoms of the following disorders can be similar to those of Freeman-Sheldon syndrome. Comparisons may be useful for a differential diagnosis:. Affected individuals also have small, fixed facial features and exhibit various abnormalities of the eyes, some of which may cause impaired vision.
The range and severity of symptoms may vary from case to case. Schwartz-Jampel syndrome is thought to be inherited as an autosomal recessive trait. Distal arthrogryposis type 1 is a rare inherited disorder characterized by fingers that are permanently flexed camptodactyly in an outward position and away from the thumb ulnar deviation. The physical features and symptoms associated with the disorder are less severe than those associated with distal arthrogryposis types 2A and 2B.
Distal arthrogryposis type 1 is inherited as an autosomal dominant trait. Distal arthrogryposis type 2B, also known as Sheldon-Hall syndrome, was once considered a variant of Freeman-Sheldon syndrome, but is now considered a separate rare inherited contracture disorder. Sheldon-Hall syndrome is characterized by physical findings and symptoms that are similar, but less severe, than those associated with Freeman-Sheldon syndrome.
Distal arthrogryposis type 2B is inherited as an autosomal dominant trait. Arthrogryposis multiplex congenita AMC is a broad group of disorders characterized by a wide spectrum of symptoms and physical features that may vary greatly in range and severity from case to case. The major form of arthrogryposis multiplex congenita is known as amyoplasia. The defect of the muscle tendons causes the fingers to curve or bend camptodactyly when the hand is bent back at the wrist dorsiflexion. Individuals with this disorder may have a slightly shorter than usual stature.
Complications associated with this disorder include difficulty in chewing mastication and walking. The severity of symptoms may vary from case to case. Trismus-pseudocamptodactyly syndrome is inherited as an autosomal dominant trait.
Gordon syndrome is an extremely rare disorder that belongs to a group of genetic disorders known as the distal arthrogryposes. These joints tend to be permanently fixed in a bent or flexed position contractures. Gordon syndrome is characterized by the permanent fixation of several fingers in a flexed position camptodactyly , abnormal bending inward of the foot clubfoot or talipes , and, less frequently, incomplete closure of the roof of the mouth cleft palate.
In some cases, additional abnormalities may also be present. Gordon syndrome is inherited as an autosomal dominant trait. Simosa craniofacial syndrome is an extremely rare inherited disorder characterized by malformations of the head and face. The face may be elongated and flattened with malformed ears. The eyebrows may be abnormally thin and highly arched.
Abnormalities affecting the eyes include folds of skin over the inner corners of the eyes epicanthal folds , and decreased height of the openings between the eyelids palpebral fissures. The nose may be unusually long with underdeveloped hypoplastic nostrils nares. The vertical groove between the nose and the upper lip philtrum may be abnormally long. Individuals with this disorder may also have a nasal quality to their voice. Simosa craniofacial syndrome is inherited as an autosomal dominant trait.
Burton syndrome is an extremely rare disorder characterized by malformations of the bones skeletal dysplasia in association with certain distinctive facial features.
Individuals with this disorder have short stature due to shortening of the shafts diaphyses of the long bones short limbed dwarfism. The long bones of the legs and arms may be dumbbell-shaped, and the portions of the long bones that naturally widen at the ends metaphyses may be unusually flared. Some affected individuals have club foot talipes equinovarus. The bones of the spine vertebrae may be flattened platyspondyly with abnormal widening of the grooves clefts in these bones.
The ribs may be unusually wide and short and the hip bones ilia may be underdeveloped hypoplastic. Individuals with this disorder have characteristic facial features consisting of an abnormally small mouth microstomia , and pursed lips. In addition, the lenses of the eyes may be displaced ectopia lentis. In some cases, the neck may be unusually short and the upper chest thorax may be narrow.
Burton syndrome is thought to be inherited as an autosomal recessive trait. The diagnosis of Freeman-Sheldon syndrome may be confirmed based upon a thorough clinical evaluation, the identification of characteristic physical findings, a detailed patient history, and specialized testing such as advanced imaging techniques.
In some cases, the disorder may be diagnosed before birth prenatally using fetal ultrasonography to identify characteristic physical abnormalities. In fetal ultrasonography, an image of the developing fetus is created using sound waves.
You may need to register to view the medical textbook, but registration is free. Children born with Edwards syndrome may have some or all of these characteristics: kidney malformations, structural heart defects at birth i. Help with Travel Costs. No organic disease can be found and extension of the fingers is always possible under anesthesia. The effects of the extra copy vary greatly, depending on the extent of the extra copy, genetic history, and chance.

Treatment may involve injection of a corticosteroid into a tender nodule or, if the hand is already scarred, injection of collagenase into a nodule or surgery to correct contracted clawed fingers. See also Overview of Hand Disorders. Dupuytren contracture is a common hereditary disorder that occurs particularly in men, especially after age However, having the abnormal gene does not guarantee that someone will have the disorder.
When only one hand is affected, the right hand is affected twice as often as the left. The disorder is occasionally associated with other disorders, including thickening of fibrous tissue above the knuckles Garrod pads , shrinking of fascia inside the penis that leads to deviated and painful erections penile fibromatosis [ Peyronie disease ] , and, rarely, nodules on the soles of the feet plantar fibromatosis.
However, the specific factors that cause the fascia of the palm to thicken and curl in are unknown. The nodule may initially cause discomfort but gradually becomes painless.
Gradually, the fingers begin to curl. Eventually, the curling worsens, and the hand can become arched clawlike. An injection of a corticosteroid into the nodule may help decrease the tenderness in the area if it is done before the fingers begin to curl. However, the tenderness often resolves without treatment. The injection does not delay the progression of the disorder. Surgery is usually needed when the hand cannot be placed flat on a table, when the fingers curl so much that hand function is limited, or when multiple fingers are involved.
Surgery to remove the diseased fascia is difficult because the fascia surrounds nerves, blood vessels, and tendons. Dupuytren contracture may return after surgery if removal of the fascia is incomplete or newly diseased fascia have developed, especially in people who developed the disorder at a young age or have family members affected by the disorder or in people who have Garrod pads, Peyronie disease, or nodules on the soles of the feet.

Freeman Sheldon Syndrome - NORD (National Organization for Rare Disorders)
Back to Health A to Z. Edwards' syndrome, also known as trisomy 18, is a rare but serious genetic condition that causes a wide range of severe medical problems. Some babies with less severe types of Edwards' syndrome, such as mosaic or partial trisomy 18, do survive beyond a year and, very rarely, into early adulthood.
But they are likely to have severe physical and mental disabilities. Each cell in your body normally contains 23 pairs of chromosomes, which carry the genes you inherit from your parents. But a baby with Edwards' syndrome has three copies of chromosome number 18, instead of two. Edwards' syndrome is rarely inherited and is not caused by anything the parents have done. The development of three copies of chromosome 18 usually happens at random during the formation of either the egg or sperm.
However, the chance of having a baby with Edwards' syndrome does increase as the mother gets older. Mosaic trisomy 18 can be a less severe form of Edwards' syndrome, as only some of the cells have the extra copy of chromosome 18, rather than every cell. How severely affected the baby is depends on the number of and type of cells that have the extra chromosome. Some babies may only be mildly affected, while some can be severely disabled.
Around seven in every 10 babies born with mosaic trisomy will live for at least a year and, in rare cases, may survive into early adulthood. In partial trisomy 18 only a section of the additional chromosome 18 is present in the cells, rather than a whole additional chromosome How severely affected the baby is will depend on which part of chromosome 18 is present in the cells. Pregnant women are offered screening for Edwards' syndrome between 10 and 14 weeks of pregnancy to assess the chances of their baby having the condition.
This screening test is known as the combined test, and it also screens for Down's syndrome and Patau's syndrome. During the combined test you will have a blood test and a special ultrasound scan where the fluid at the back of the baby's neck nuchal translucency is measured. If the combined test shows that you have a higher risk of having a baby with Edwards' syndrome, you will be offered a diagnostic test to find out for certain if your baby has the condition.
There are two different ways of getting this sample of cells — chorionic villus sampling , which collects a sample from the placenta, or amniocentesis , which collects a sample of the amniotic fluid from around your baby. These are invasive tests that do have a risk of causing a miscarriage.
Your doctor will discuss these risks with you. Later in pregnancy, usually when you are weeks pregnant, you will also be offered a scan that looks for physical abnormalities, known as congenital anomalies. A newer test has also been developed that can be performed by taking a sample of blood from the mother, at weeks, and testing the baby's DNA that is found within it. If doctors believe a baby has Edwards' syndrome when it is born they will take a blood sample from the baby.
This will be examined to see if the baby's cells have extra copies of chromosome If your baby is diagnosed with Edwards' syndrome during your pregnancy your doctor will talk to you about how you want to move forward.
They will discuss the options of either continuing with the pregnancy or ending it with a termination, as it is such a severe condition.
This is a very difficult situation and it is normal to feel a whole range of emotions. It may help to talk to your doctor, partner, family and friends about what you are thinking and how you are feeling. If your baby is diagnosed with Edwards' syndrome, either before birth or afterwards, you'll be offered counselling and support.
The helpline is answered by trained staff, who can offer information and support. There is no cure for Edwards' syndrome and the symptoms can be very difficult to manage. You are likely to need help from a wide range of health professionals. Treatment will focus on immediately life-threatening issues, such as infections and heart problems. Your child may also need to be fed through a feeding tube, as feeding is often a problem. If limb abnormalities affect your child's movements as they get older, they may benefit from supportive treatment, such as physiotherapy and occupational therapy.
Depending on your child's specific problems, they may need specialist care in hospital or a hospice, or you may be able to look after them at home with appropriate support. Caring for a child with Edwards' syndrome is mentally and physically challenging. Your guide to care and support provides lots of advice on how you can take time to look after yourself, including:. This helps scientists look for better ways to prevent and treat this condition.

The presence of this extra chromosome in cells severely disrupts normal development. Mosaic trisomy 18 Mosaic trisomy 18 can be a less severe form of Edwards' syndrome, as only some of the cells have the extra copy of chromosome 18, rather than every cell.
Partial trisomy 18 In partial trisomy 18 only a section of the additional chromosome 18 is present in the cells, rather than a whole additional chromosome Symptoms of Edwards' syndrome Babies with Edwards' syndrome can have a wide range of different problems. Physical signs of Edwards' syndrome include: low birthweight a small, abnormally shaped head a small jaw and mouth long fingers that overlap, with underdeveloped thumbs and clenched fists low-set ears smooth feet with rounded soles a cleft lip and palate an exomphalos where the intestines are held in a sac outside the tummy Babies with Edwards' syndrome also typically have: heart and kidney problems feeding problems — leading to poor growth breathing problems hernias in the wall of their stomach where internal tissues push through a weakness in the muscle wall bone abnormalities — such as a curved spine frequent infections of the lungs and urinary system a severe learning disability Diagnosing Edwards' syndrome During pregnancy Pregnant women are offered screening for Edwards' syndrome between 10 and 14 weeks of pregnancy to assess the chances of their baby having the condition.
After birth If doctors believe a baby has Edwards' syndrome when it is born they will take a blood sample from the baby.
