Stickler Syndrome

Summary about Disease


Stickler syndrome is a group of genetic disorders that affect connective tissue, particularly collagen. This can lead to a variety of problems affecting the eyes, ears, bones, joints, and face. The severity and specific symptoms vary widely among affected individuals.

Symptoms


Eyes: Myopia (nearsightedness), cataracts, glaucoma, retinal detachment.

Ears: Hearing loss (often progressive), recurrent ear infections.

Skeletal: Joint pain and stiffness (early onset arthritis), scoliosis, mild to moderate short stature.

Facial: Flattened facial appearance, small or recessed chin, cleft palate (sometimes), Pierre Robin sequence (small jaw, tongue that falls back, and cleft palate).

Causes


Stickler syndrome is caused by mutations in genes that provide instructions for making collagen. Collagen is a protein that provides strength and support to connective tissue throughout the body. Different gene mutations are associated with different types of Stickler syndrome. The most common genes involved are COL2A1, COL11A1, and COL11A2. The condition is typically inherited in an autosomal dominant pattern, meaning only one copy of the mutated gene is needed to cause the disorder.

Medicine Used


There is no cure for Stickler syndrome, so treatment focuses on managing specific symptoms.

Eyes: Glasses or contacts for vision correction, surgery for cataracts or retinal detachment.

Ears: Hearing aids for hearing loss, antibiotics for ear infections.

Skeletal: Pain relievers (over-the-counter or prescription), physical therapy, bracing or surgery for scoliosis or joint problems.

Other: Speech therapy for cleft palate.

Is Communicable


No, Stickler syndrome is not communicable. It is a genetic disorder, meaning it is caused by a gene mutation and cannot be spread from person to person.

Precautions


Since Stickler syndrome is a genetic condition, there are no precautions to prevent getting it. Precautions focus on managing existing symptoms and preventing complications:

Regular eye exams to monitor vision and detect retinal detachment early.

Hearing tests to monitor hearing loss.

Protecting joints from injury.

Genetic counseling for families with a history of Stickler syndrome.

How long does an outbreak last?


Stickler syndrome is not an infectious disease; therefore, the term "outbreak" is not applicable. It is a chronic condition with symptoms that can persist throughout life, although the severity and progression can vary.

How is it diagnosed?


Diagnosis is based on a clinical evaluation, which includes:

Physical examination to assess for characteristic features.

Eye examination (ophthalmologic exam).

Hearing test (audiogram).

X-rays to evaluate skeletal abnormalities.

Genetic testing to confirm the diagnosis by identifying a mutation in a related gene.

Timeline of Symptoms


The timeline of symptoms can vary greatly among individuals with Stickler syndrome.

Infancy/Childhood: Cleft palate (if present) is evident at birth. Myopia and hearing loss may be detected early. Joint problems may begin to manifest. Facial features are usually noticed.

Adolescence/Adulthood: Joint pain and arthritis may worsen. Hearing loss may progress. Eye problems may require ongoing management. Scoliosis may develop or progress.

Important Considerations


Early diagnosis and intervention are crucial to manage symptoms and prevent complications.

A multidisciplinary team of specialists (ophthalmologist, audiologist, orthopedic surgeon, geneticist, etc.) is essential for comprehensive care.

Genetic counseling is recommended for families who are considering having children.

Individuals with Stickler syndrome should be aware of the potential risks of retinal detachment and joint problems.

Support groups can provide valuable information and emotional support for individuals and families affected by Stickler syndrome.
