Can you see with Fraser syndrome?
Eye abnormalities typically lead to impairment or loss of vision in people with Fraser syndrome. Affected individuals can have other problems related to abnormal eye development, including missing eyebrows or eyelashes or a patch of hair extending from the side hairline to the eyebrow.
Can Fraser syndrome be cured?
There is currently no cure for Fraser syndrome. Treatment of FS may include surgery to correct some of the malformations associated with this disorder depending on their severity. Other treatment is symptomatic and supportive.
Can Fraser syndrome be detected before birth?
The prenatal diagnosis of Fraser Syndrome is frequently possible. The prenatal ultrasound can reveal features like polyhydramnios or oligohydramnios, echogenic lungs, renal abnormalities or agenesis and cryptophthalmos that are pathognomonic of the Fraser Syndrome.
How common is Frasier Syndrome?
Frasier syndrome is thought to be a rare condition; approximately 50 cases have been described in the scientific literature.
How long do people live with Fraser syndrome?
Fraser syndrome is an autosomal recessive disorder in which the life expectancy is <1 year. The main features are cryptophthalmos, ear, nose and skeletal malformations, syndactyly, laryngeal stenosis and malformation of the uro-genital system, lungs, liver and central nervous system (CNS).
What affects the larynx of babies with Fraser syndrome?
Since the larynx is one of the parts with membrane fusion, this syndrome may also affect the larynx and especially the vocal folds. This laryngeal disorder can cause for respiration and vocalization.

What causes Fraser syndrome?
Fraser syndrome is caused by mutations in three different genes : FRAS1, GRIP1, and FREM2 and is inherited in an autosomal recessive manner. This condition is diagnosed based on signs and symptoms. Genetic testing may be useful to confirm the diagnosis.

What is Frasier syndrome?
Fraser syndrome is named after the Canadian geneticist George R. Fraser who first described the syndrome in 1962. Fraser syndrome is characterized by multiple physical abnormalities.

What are the physical findings characteristic of Fraser syndrome?
Fraser syndrome is characterized by multiple physical abnormalities. Failure of the eyelids to form properly (cryptophthalmos) is the most common abnormality, seen in 93% of affected individuals. Other less common forms of cryptophtalmos seen in these individuals are only one eye completely covered by skin, or one or both eyes partially covered.
Is Fraser syndrome recessive or dominant?
Causes. Fraser syndrome is an autosomal recessive genetic disorder. The mutant gene has been tracked to the long arm of chromosome 4 (4q21). Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual. Human body cells normally have 46 chromosomes.
What is the prevalence of Fraser syndrome?
Fraser syndrome is a rare, autosomal recessive disorder characterized by cryptophthalmos, syndactyly, and renal agenesis or obstructive uropathy.100 The cryptophthalmos is present in 85% and is bilateral in 70% of these cases. Syndactyly occurs in approximately 80% of cases and may be partial or complete.
