Stickler syndrome types I, II, and III are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits a gene mutation from one affected parent . Other cases result from new mutations .
Is Stickler syndrome hereditary?
Stickler syndrome is a genetic disorder that can cause serious vision, hearing and joint problems. Also known as hereditary progressive arthro-ophthalmopathy, Stickler syndrome is usually diagnosed during infancy or childhood.
Is Stickler syndrome dominant or recessive?
Stickler syndrome can be inherited in an autosomal dominant manner or in an autosomal recessive manner depending on the gene that has a change ( mutation or pathogenic variant). When Stickler syndrome is caused by pathogenic variants in COL2A1, COL11A1, or COL11A2, it is inherited in an autosomal dominant manner.
Can Stickler syndrome skip a generation?
Unlike some genetic syndromes, a person will not have a “carrier” gene for this disorder that can be passed on to the next generation without the parent having Stickler syndrome themselves.
What are the chances of getting Stickler syndrome?
A: Stickler syndrome is a fairly common genetic condition, occurring in about one in 7,500 people in the United States and Europe. It’s also frequently misdiagnosed—or even left undiagnosed—because many people have very mild cases.
Is Stickler syndrome a disability?
If you or your dependent(s) are diagnosed with Stickler Syndrome and experience any of these symptoms, you may be eligible for disability benefits from the U.S. Social Security Administration.
Can Stickler syndrome be prevented?
You cannot prevent Stickler syndrome. People with a family history of the condition who want to have children should seek genetic counseling to learn about the risk of having a child with the disorder.
Can Stickler syndrome be detected before birth?
What about genetic testing? Molecular genetic testing can be used to diagnose Stickler syndrome. A clinical geneticist can discuss this in detail with you and arrange for it, if appropriate. Your doctor may suggest it to confirm a suspected diagnosis or for prenatal diagnosis.
What is Pierre Robin Syndrome?
Pierre Robin sequence is also known as Pierre Robin syndrome or Pierre Robin malformation. It is a rare congenital birth defect characterized by an underdeveloped jaw, backward displacement of the tongue and upper airway obstruction. Cleft palate is also commonly present in children with Pierre Robin sequence.
What is Crouzon syndrome?
Crouzon syndrome is a rare genetic disorder. It is a form of craniosynostosis, a condition in which there is premature fusion of the fibrous joints (sutures) between certain bones of the skull. The sutures allow an infant’s head to grow and expand. Eventually, these bones fuse together to form the skull.

How do you test for Stickler syndrome?
Stickler syndrome is diagnosed with a physical examination, although there is currently no consensus as to the diagnostic criteria. The diagnosis can be confirmed by testing for mutations within genes called COL2A1, COL11A1 and COL11A2 for cases of autosomal dominant types of Stickler syndrome.
How many types of Stickler syndrome are there?
There are five types of Stickler syndrome: Stickler syndrome type I, Stickler syndrome type II, Stickler syndrome type III, Stickler syndrome type IV, and Stickler syndrome type V. Individuals with Stickler syndrome type I tend to have milder hearing loss, nearsightedness, and type 1 membranous vitreous anomaly.
What does stickler for the rules mean?
1 : one who insists on exactness or completeness in the observance of something a stickler for the rules. 2 : something that baffles or puzzles : poser.
Does Stickler syndrome get worse with age?
Features even vary among affected members of the same family. In some cases, a person may have multiple features, but only one problem is severe enough to be diagnosed. Stickler syndrome is also a progressive disorder, therefore, the symptoms are likely to worsen with age.
