Freeman–Sheldon Syndrome (FSS) is a rare genetic disorder characterized by distinctive facial features, abnormalities of the hands and feet, and joint contractures. It is also known as Windblown Syndrome, Sheldon–Hall Syndrome or Distal Arthrogryposis Type 2A. The condition is caused by a mutation in the MYH3 gene which affects the production of muscle proteins needed for normal development. FSS can cause severe physical disability and life-threatening complications in some cases. The severity of the condition varies from person to person, but most people with FSS require life-long medical care. Freeman-Sheldon Syndrome (FSS) is a rare congenital disorder characterized by distinctive facial features, joint contractures, and skeletal deformities. It is also known as Windmill Vane Hand Syndrome. The facial features include pursed lips, a whistling face, downturned mouth, prominent eyes, and an upwardly arched nasal bridge. Joint contractures involve the arms and legs, resulting in a “windmill vane” hand deformity. Skeletal deformities may include scoliosis, chest deformities, and club feet. Other signs and symptoms may include short stature; delayed motor development; hearing loss; vision problems; heart defects; and intellectual disability.

What is Freeman–Sheldon Syndrome?

Freeman–Sheldon Syndrome, also known as Windmill Vane Hand Syndrome, is a rare genetic disorder characterized by craniofacial deformities, skeletal abnormalities, and contractures of the hands and feet. It is one of the most severe forms of congenital contracture syndromes and is caused by a spontaneous mutation in the MYH3 gene. The effects of this disorder are lifelong and can cause physical disability, breathing difficulties, difficulty speaking, and poor cognition.

Symptoms of Freeman–Sheldon Syndrome

The most common symptoms of Freeman–Sheldon Syndrome include contractures of the fingers and toes, distinctive facial features such as a small lower jaw (micrognathia), malformed ears, high-arched palate, abnormal formation of the bone in the upper jaw (maxilla), cleft lip or palate, thin upper lip with downturned corners (whistling face), drooping eyelids (ptosis), crossed eyes (strabismus), an abnormally small head (microcephaly) , joint deformities, clawed hands and feet with abnormally curved fingers (camptodactyly), weak muscles in the trunk and limbs (hypotonia), scoliosis or curvature of the spine , delayed development , breathing difficulties due to an abnormally shaped chest wall (pectus carinatum) , heart defects , hearing loss , vision problems , abnormal growth patterns and other medical complications.

Causes of Freeman–Sheldon Syndrome

Freeman–Sheldon Syndrome is caused by a spontaneous mutation in the MYH3 gene which encodes myosin-3 heavy chain protein. This protein is essential for proper muscle development and function. The mutated gene affects muscle formation resulting in joint contractures which cause physical disability. Other genetic mutations have been linked to increased risk for Freeman–Sheldon Syndrome including mutations in genes involved in bone formation such as RUNX2 and mutations in genes involved in muscle development such as DCHS1. Environmental factors may also play a role in increasing risk for this condition.

Diagnosis & Treatment for Freeman–Sheldon Syndrome

Diagnosis of Freeman–Sheldon Syndrome is based on clinical presentation including physical examination to assess skeletal abnormalities and contractures. Genetic testing may be used to confirm diagnosis. Treatment for this condition typically involves physical therapy to improve range of motion, orthopedic surgery to correct joint deformities if needed, speech therapy to improve speaking ability if needed, occupational therapy if needed for daily living activities.

Overview of Freeman–Sheldon Syndrome

Freeman–Sheldon Syndrome (FSS) is a rare genetic disorder which causes malformations of the hands, feet, face and other parts of the body. It is a type of craniosynostosis, a condition in which the bones in the skull grow together too soon. FSS usually appears at birth and affects both genders equally. Some common signs and symptoms of FSS include: webbed fingers and toes, facial abnormalities such as an unusually small jaw (micrognathia) and a pursed-lip facial expression, joint contractures, scoliosis and dislocated hips. Other associated features may include hearing loss, heart defects, intellectual disabilities and eye problems.

Signs & Symptoms of Freeman–Sheldon Syndrome

The most common signs and symptoms of Freeman–Sheldon Syndrome include:

  • Webbed fingers and toes (syndactyly)
  • Facial abnormalities such as an unusually small jaw (micrognathia) or a pursed-lip expression
  • Joint contractures that limit movement in certain joints
  • Scoliosis (curvature of the spine)
  • Dislocated hips or other hip problems
  • Hearing loss or eye problems such as cataracts
  • Heart defects or heart murmurs
  • Intellectual disability or developmental delay

The severity of these signs and symptoms can vary from person to person. Some individuals may have only mild signs while others may have more severe symptoms that affect their daily life activities. It is important to note that not all individuals with FSS will experience all of these signs and symptoms. Individuals with this syndrome should be monitored closely by their healthcare providers for any changes in their condition.

Diagnosis of Freeman–Sheldon Syndrome

Freeman–Sheldon Syndrome (FSS) is a rare congenital disorder characterized by facial, hand and foot deformities. It is often diagnosed in infancy or early childhood. The diagnosis of FSS is based on the presence of certain clinical features that can be detected through physical examination or medical imaging.

The primary signs of FSS are a distinct facial pattern, contractures of the hands and feet, and distinctive muscle weakness. The facial features include pursed lips, a high-arched palate, and an upward-slanting palpebral fissure (eyelid opening). In addition, individuals with FSS may have a depressed nasal bridge, a small chin, and malformed ears.

Contractures of the hands and feet often involve the fingers or toes being held in a flexed position or overlapping each other. This can lead to limited range of motion in the affected areas. Muscle weakness is also common in individuals with FSS, resulting in difficulty with activities such as walking or running.

A diagnosis of FSS requires two out of three criteria to be met: the presence of facial features associated with FSS; contractures affecting at least two joints; and/or muscle weakness involving one or more muscles groups. Medical imaging such as X-rays or MRI scans may also be used to confirm the diagnosis by providing evidence of skeletal abnormalities associated with the disorder.

In some cases, genetic testing may be used to help determine if an individual has FSS by looking for mutations in certain genes associated with the disorder. However, this type of testing is not always reliable as there are many other genetic conditions that can cause similar symptoms to those seen in individuals with FSS.

Once an individual has been diagnosed with FSS, they should receive appropriate medical care and management to help reduce any discomfort caused by their condition. This can include medications to reduce inflammation and pain relief therapies such as massage therapy or physical therapy to improve range of motion. Surgery may also be recommended for some individuals to correct any skeletal deformities present which can help improve their quality of life.

Overall, diagnosing Freeman–Sheldon Syndrome requires careful evaluation by a medical professional who will look for specific clinical features such as facial deformities combined with contractures and/or muscle weakness. In some cases additional testing such as genetic analysis may be needed for confirmation but it is not always reliable for making an accurate diagnosis.

Complications of Freeman–Sheldon Syndrome

Freeman-Sheldon Syndrome (FSS) is a rare genetic disorder characterized by deformities in the face, hands, and feet. While having FSS can be a challenging condition, it can also lead to serious complications. These complications can range from respiratory issues to joint problems and even heart and urinary problems. Below we outline some of the most common complications that may arise with FSS.

Respiratory Issues: People with Freeman-Sheldon Syndrome may experience difficulty breathing due to abnormal muscle development in the chest and throat. This can lead to problems such as chronic coughing, shortness of breath, wheezing, frequent respiratory infections, and sleep apnea.

Joint Problems: Those with FSS often have abnormally developed joints in the hands and feet, which can make everyday activities difficult or painful. This may lead to decreased mobility or difficulty performing certain movements with the hands and feet.

Heart Problems: People with Freeman-Sheldon Syndrome may be more prone to heart defects due to abnormal development of the chest muscles. This could include congenital heart defects or cardiac arrhythmias that can cause palpitations or other symptoms.

Urinary Issues: Abnormal muscle development in the pelvic area can result in urinary tract issues such as incontinence or urinary tract infections (UTIs). It is important for those with FSS to take extra precautions when it comes to hygiene and urinary health.

It is important for those with Freeman-Sheldon Syndrome to be aware of potential complications so they can take preventive measures as well as seek medical attention when necessary. With proper care management, those living with FSS can live a long and healthy life despite their condition.
