About Antley-Bixler Syndrome
What is Antley-Bixler Syndrome?
Antley-Bixler Syndrome (ABS) is a rare genetic disorder that affects the development of the bones, joints, and other organs. It is characterized by skeletal malformations, including craniosynostosis (premature fusion of the skull bones), midface hypoplasia (underdevelopment of the midface), and choanal atresia (narrowing or blockage of the nasal passages). Other features may include cleft palate, hearing loss, eye abnormalities, and heart defects. ABS is caused by mutations in one of several genes, including FGFR2, FLNA, and POR. Treatment is based on the individual's symptoms and may include surgery, physical therapy, and medications.
What are the symptoms of Antley-Bixler Syndrome?
The symptoms of Antley-Bixler Syndrome vary from person to person, but some of the most common symptoms include:
-Craniofacial abnormalities, such as a cleft palate, a flattened midface, and a prominent forehead
-Skeletal abnormalities, such as joint dislocations, scoliosis, and clubfoot
-Cardiac defects, such as ventricular septal defects and patent ductus arteriosus
-Respiratory problems, such as tracheomalacia and choanal atresia
-Gastrointestinal problems, such as malrotation and esophageal atresia
-Genitourinary problems, such as hypospadias and cryptorchidism
-Neurological problems, such as hydrocephalus and seizures
-DevelopMental delays and
What are the causes of Antley-Bixler Syndrome?
Antley-Bixler Syndrome is a rare genetic disorder caused by mutations in the FGFR2 gene. These mutations can be inherited from a parent or can occur spontaneously.
What are the treatments for Antley-Bixler Syndrome?
The treatments for Antley-Bixler Syndrome vary depending on the individual and the severity of the condition. Generally, treatment focuses on managing the symptoms and complications associated with the condition. This may include physical therapy, occupational therapy, speech therapy, orthopedic surgery, and/or hormone replacement therapy. In some cases, medications may be prescribed to help manage pain, inflammation, and other symptoms. Additionally, genetic counseling may be recommended for families affected by Antley-Bixler Syndrome.
What are the risk factors for Antley-Bixler Syndrome?

• Family history of the disorder
• Exposure to certain medications or environmental toxins during pregnancy
• Maternal diabetes
• Maternal obesity
• Maternal age over 35
