What is the cause of Crouzon syndrome?
Mutations in the FGFR2 gene cause Crouzon syndrome. This gene provides instructions for making a protein called fibroblast growth factor receptor 2. Among its multiple functions, this protein signals immature cells to become bone cells during embryonic development.
What is the life expectancy of someone with Crouzon syndrome?
People with Crouzon syndrome have a normal life expectancy. Most children with this condition are unaffected intellectually. However, it can alter the shape of the face and cause vision and hearing problems.
Is Crouzon syndrome a disability?
The severity of signs and symptoms can vary among affected people, even within a family. Intelligence is usually normal, but intellectual disability may be present. Crouzon syndrome is caused by changes ( mutations ) in the FGFR2 gene and is inherited in an autosomal dominant manner.
Why is it called Pfeiffer syndrome?
The syndrome is named after German geneticist Rudolf Arthur Pfeiffer (1931–2012). In 1964, Pfeiffer described eight individuals in three generations of a family who had abnormalities of the head, hands and feet (acrocephalosyndactylia) that were inherited in an autosomal dominant pattern.
Can Crouzon syndrome be inherited?
Crouzon syndrome is caused by alterations (mutations) in one of the FGFR genes, usually FGFR2, and is inherited in an autosomal dominant manner.
Can Crouzon syndrome be detected before birth?
Crouzon syndrome is usually diagnosed at birth, based on the appearance of your child’s face and skull. Our expert craniofacial team will confirm a diagnosis of this condition and help you make decisions about your child’s care.
How do you fix Crouzon syndrome?
Treatment of Crouzon syndrome may include surgery. This is to improve symptoms, prevent complications, and help physical and mental development. If the fused sutures are causing intracranial pressure, this may lead to brain injury. This is treated with craniofacial or open vault surgery.
How is Crouzon treated?
Who is at risk for Pfeiffer syndrome?
Advanced paternal age is associated with an increased risk for new mutations for Pfeiffer syndrome. The risk of passing the abnormal gene from an affected parent to offspring is 50% for each pregnancy. The risk is the same for males and females. Pfeiffer syndrome type I is associated with mutations in FGFR1 and FGFR2.
Can Pfeiffer syndrome be cured?
There is no cure for Pfeiffer syndrome. Treatment will depend on the child’s symptoms. Surgery is the main treatment and may include one or more of the following: Skull surgery: The initial surgery to reshape the child’s head is done as early as three months and by 18 months of age.
Can Crouzon syndrome be detected in ultrasound?
We report a rare case of prenatal diagnosis of familial Crouzon Syndrome by subtle 2D ultrasound findings of brachycephaly, proptosis with easily visible palpebrae, depressed nasal bridge and a beaked nose in a fetus at 32 weeks of period of gestation.
Is Crouzon hereditary?
How is Crouzon syndrome inherited? Crouzon syndrome is inherited in an autosomal dominant manner. This means that having a change ( mutation ) in only one copy of the responsible gene in each cell is enough to cause features of the condition.
