Apert Syndrome
1
Overview
Apert syndrome is a genetic disorder characterized
by the premature fusion of certain skull bones
(craniosynostosis). This early fusion prevents the
skull from growing normally and affects the shape
of the head and face. In addition, a varied number
of fingers and toes are fused together (syndactyly).
2
Overview
Many of the characteristic facial features of Apert
syndrome result from the premature fusion of the
skull bones. The head is unable to grow normally,
which leads to a sunken appearance in the middle
of the face, bulging and wide-set eyes, a beaked
nose, and an underdeveloped upper jaw leading to
crowded teeth and other dental problems. Shallow
eye sockets can cause vision problems. Early fusion
of the skull bones also affects the development of
the brain, which can disrupt intellectual developm
3
Overview
Individuals with Apert syndrome have webbed or
fused fingers and toes. The severity of the fusion
varies; at a minimum, three digits on each hand
and foot are fused together. In the most severe
cases, all of the fingers and toes are fused. Less
commonly, people with this condition may have
extra fingers or toes (polydactyly). Additional signs
and symptoms of Apert syndrome can include
hearing loss, unusually heavy sweating
(hyperhidrosis), oily skin with severe acne, patches
of missing hair in t
4
Symptoms
Early closure of sutures between bones of the
skull, noted by ridging along sutures
Frequent ear infections
Fusion or severe webbing of the 2nd, 3rd, and 4th
fingers, often called "mitten hands"
5
Symptoms
Hearing loss
Large or late-closing soft spot on a baby's skull
Possible, slow intellectual development (varies
from person to person)
Prominent or bulging eyes
Severe under-development of the mid-face
6
Symptoms
Skeletal (limb) abnormalities
Short height
Webbing or fusion of the toes
Several other syndromes can lead to a similar
appearance of the face and head, but do not
include the severe hand and foot problems of
Apert syndrome. These similar syndromes include:
7
Symptoms
Carpenter syndrome (kleeblattschadel, cloverleaf
skull deformity)
Crouzon disease (craniofacial dysostosis)
Pfeiffer syndrome
Saethre-Chotzen syndrome
8
Diagnosis
The doctor will perform a physical exam. Hand,
foot, and skull x-rays will be done. Hearing tests
should always be performed.
Genetic testing can confirm the diagnosis of Apert
syndrome.
9
Treatment
Treatment consists of surgery to correct abnormal
bone growth. Children with this disorder should be
examined by a specialized craniofacial surgery
team at a children's medical center.
A hearing specialist should be consulted if there
are hearing problems.
10
Causes
Apert syndrome can be passed down through
families (inherited). The syndrome is inherited as
an autosomal dominant trait, which means that
only one parent needs to pass on the faulty gene
for a child to have the condition.
Some cases may occur without a known family
history.
11
Causes
Apert syndrome is caused by mutations in a gene
called fibroblast growth factor receptor 2. This
gene defect causes some of the bony sutures of
the skull to close too early, a condition
called craniosynostosis.
12
Prevention
Genetic counseling may be helpful if you have a
family history of this disorder and are planning to
become pregnant. Your doctor can test your baby
for this disease during pregnancy.
