Apert Sydrome:
Overview:
In 1906, a French neurologist first described the features of this syndrome
that now bears his name. Apert syndrome results from a mutation (or change)
in a single gene located on chromosome 10q. There are actually two different
mutations on this chromosome that can produce Apert syndrome (they are:
Ser252Trp and Pro253Arg), and researchers are studying to see if one mutation
causes a slightly different "type" of Apert from the other. Currently,
no one knows what causes this mutation to occur. Typically, both the mother
and father of a child born with Apert syndrome have normal genes, and
the mother does "everything right" during her pregnancy. The process of
bringing genes together from a mother and father is quite complicated.
Once in awhile, a gene can be changed in the process. If this occurs in
the "right" gene, Apert syndrome results. The chances of two parents,
neither of whom have Apert syndrome themselves, of having a child with
Apert syndrome has been estimated to be as high as 1:120,000 (Could you
have Apert syndrome and not know it? The answer is: no.). However, the
most recent data suggests that this condition is more common, and occurs
in approximately 1:65,000 births. Apert syndrome can be inherited, and
is transmitted in what geneticists call an "autosomal dominant pattern."
This means that when a child grows up with Apert syndrome and chooses
to have children, there is a 50:50 chance that the Apert trait will be
passed on for each birth. In the very near future, it will be possible
for individuals who have Apert syndrome, to elect to not pass on this
trait. In order to ensure that this trait is not passed on, it will be
necessary to undergo in-vitro fertilization selecting embryos that do
not have the Apert substitution.
Physical Traits:
Apert syndrome affects multiple places around the body. Some individuals
will have some of the following traits and others will not. This list
is not complete, but does include the more common findings.
Skin | Skull
| Brain | Eyes
& Midface | Ears
| Mouth | Heart
| Stomach &
Intestines | Hands
& Feet | Other
Joints
Treatment:
The treatment of a child born with Apert syndrome is complex, and is probably
best provided by comprehensive craniofacial teams at major centers. The
following is a brief overview of my recommended treatment protocols. Specifics
should be discussed with your team of doctors.
Skull Surgery
| Sleep Apnea | Midface
Surgery | Hands
and Feet
The Big Picture:
The child born with Apert syndrome, and his or her family, spend too much
time in the hospital. I believe that children with Apert syndrome should
not be put to sleep for a single small operation to be done by only one
doctor, multiple times a year. It is important that every time a child
with Apert syndrome needs to go to sleep in the operating room, all the
specialists coordinate their care so that as much gets done as possible
with each anesthetic. It is also critical that the correct operation be
done the first time, and that all efforts are made to reduce complications.
I believe that it is very important that these children be given substantial
blocks of time away from the hospital so that they can grow and develop.
In order to accomplish this, children should ideally be treated at experienced
craniofacial centers.
Treatment recommendations are constantly changing over time, and will
also vary from center to center. It is important to discuss these issues
with your doctor, and make sure that all your questions get answered.
