Recently I responded in an online Agenesis Corpus 
Callosum (ACC) e-mail support group to the 
following question and thought I would share 
it here:
Can Agenesis Corpus Callosum Affect Growth?
I am also the mom of a boy, Matthew, who is adopted. 
We adopted him at birth and found out he had ACC 
when he was four months old. I think every parent 
will agree with you that receiving the diagnosis 
of ACC for their baby/child is a shock and moving 
through all of the overwhelming emotions, questions, 
concerns is not an easy task. I cried A LOT during 
the first year after my son was diagnosed and went 
through tidal waves of emotions...but it did calm 
and become easier.
YES, when a child has ACC they may also have 
growth problems and it can affect their growth. 
Because ACC can affect growth and cause other 
various hormone issues, it is very important that 
child be seen by a good pediatric endocrinologist 
to rule out any problems. 

Some children who have ACC require growth 
hormones. My own child, Matthew, began seeing 
a pediatric endocrinologist when he was younger 
because he was very short and nearly below the 
growth chart on his height. His weight was fine 
but he could wear the same shirts and pants for 
two plus years and always looked about two years 
younger than the kids in his class. He had various 
blood tests to check all of his hormones and he 
also had an x-ray of his wrist/hand to check the 
bone age. All of his hormones were fine and his x-ray 
showed that his bone age was a little over two 
years behind his real age. He was (and still is) 
followed every year by his pediatric endocrinologist 
for a check-up. Also, when a child has ACC they 
may not start into puberty or may start puberty 
too early or too late. It was explained to me 
that because the pituitary sits very close to 
where the corpus callosum should be (in the middle 
of the brain) that there is the possibility that 
the pituitary may also have a problem and may not 
function properly. My son started into puberty 
without any medical intervention or need for 
hormones and is doing fine. He didn't start 
puberty until about age 14 years. 
ACC is a midline defect and because the corpus 
callosum is in the middle of the brain there 
is the possibility that the child can have 
other midline defects (such as a cleft lip 
and/or palate. Another example is the heart 
since it is midline in the body. My son had 
a heart murmur and because he has ACC he was 
seen by a pediatric cardiologist and had tests 
to rule out any heart defects/problems. 
ACC can also be seen with other medical problems
such as chromosome anomalies, genetic syndromes, 
metabolic disorders and optic nerve or eye 
conditions. 
When a child has ACC they should be seen by a 
pediatric ophthalmologist to rule out any optic 
nerve problems and/or eye problems. Sometimes 
kids who have ACC have a wandering eye (wanders 
out or wanders in) (exotropia or esotropia) and 
they can prefer to use one eye to focus instead 
of using both eyes together. They are at risk 
for having amblyopia (permanent loss of sight) 
if they continue to use only one eye to focus 
because the brain will shut off vision permanently 
to the eye that is not being used. It is my 
understanding from our own pediatric 
ophthalmologist that the risk of amblyopia is 
possible until about the age of eight years old 
in a child. They are followed VERY closely by a 
pediatric opthalmologist to be sure that the 
child is using both eyes to focus and to help 
the weaker eye become stronger using various 
ways...such as patching the stronger eye to force 
the weaker eye to be used. Sometimes a child will 
require surgery to the eye muscle. My own son did 
require eye surgery (on his right eye only) after 
patching was not effective.
Below is a link to a list of medical options to 
consider and discuss with your child's doctor(s):
