Apert Syndrome: A Comprehensive Guide


Apert syndrome, also known as acrocephalosyndactyly type 1, is a rare genetic disorder characterized by the premature fusion of the skull bones (craniosynostosis) and syndactyly, or webbed fingers and toes. It affects approximately 1 in 65,000 to 1 in 100,000 live births.


Apert syndrome is caused by a mutation in the fibroblast growth factor receptor 2 (FGFR2) gene. This gene plays a crucial role in the development of the skull, hands, and feet. The mutation results in an abnormal form of FGFR2 that promotes premature bone fusion and inhibits the normal separation of fingers and toes.

Signs and Symptoms


  • Flattened forehead
  • Prominent eyes with wide-spaced orbits
  • Bossing (bulging) of the forehead
  • Turricephaly (pointed or tower-shaped skull)
  • Cranial sutures that are closed or closing prematurely


  • Webbing of fingers and toes, usually in a symmetrical pattern
  • Fusion of the second and third fingers
  • Fusion of the third and fourth toes
  • Toes that are angled inward (clinodactyly)

Other Features:

  • Midface retrusion (underdevelopment of the middle part of the face)
  • Downward-slanting palpebral fissures (eyelids)
  • Protruding ears
  • Short and stocky stature
  • Dental abnormalities
  • Hearing loss
  • Developmental delays (in some cases)



  • Increased intracranial pressure
  • Developmental delays
  • Eye problems (squint, double vision)
  • Sleep apnea


  • Hand deformities and functional limitations
  • Foot deformities and difficulty walking
  • Vertebral anomalies
  • Thoracic cage abnormalities


  • Hearing loss
  • Dental problems
  • Speech difficulties
  • Social and emotional challenges


Apert syndrome can be diagnosed based on the characteristic physical findings, family history, and genetic testing. X-rays or CT scans can confirm craniosynostosis. Blood or saliva testing can identify the specific FGFR2 mutation.


Surgical Intervention:

  • Cranioplasty: Surgery to reshape the skull and relieve pressure on the brain
  • Syndactyly release: Surgery to separate the webbed fingers and toes
  • Dental surgery: To correct dental abnormalities and improve bite

Nonsurgical Management:

  • Physical therapy to improve motor function and flexibility
  • Occupational therapy to promote independence with daily activities
  • Speech therapy to address speech difficulties
  • Hearing aids to improve hearing
  • Orthodontic treatment to align teeth
  • Special education and support services to assist with developmental challenges


The prognosis for individuals with Apert syndrome depends on the severity of the condition and the extent of complications. With early diagnosis and appropriate medical and surgical intervention, most individuals can live full and active lives.

Long-Term Care

Medical Management:

  • Regular monitoring of head growth, hearing, vision, and overall development
  • Treatment of complications as they arise
  • Preventive measures to minimize future health risks

Supportive Care:

  • Access to specialized healthcare providers
  • Genetic counseling for family members
  • Educational and emotional support for individuals and families
  • Advocacy and resources for access to services and care

Societal Impact

Apert syndrome can have a profound impact on the social and emotional well-being of individuals and their families. Individuals may experience stigma, bullying, and challenges with social integration. Support groups, advocacy organizations, and educational campaigns play a vital role in promoting understanding and acceptance.


Apert syndrome is a complex genetic disorder that requires comprehensive medical and surgical intervention. With early diagnosis and appropriate management, individuals can overcome the challenges associated with the condition and live full and productive lives. Ongoing research and advancements in treatment aim to improve the outcomes for individuals with Apert syndrome and their families.
