Frequently Asked
Questions
1. What is dup 7q11.23 syndrome?
Dup 7q11.23 syndrome is a rare genetic disorder in which
individuals carry an extra copy of a tiny portion of chromosome
7
2. What causes dup 7q11.23 syndrome?
The duplication on chromosome 7q11.23 is caused by an error
that happens when this part of the genome is copied (most likely
in the formation of the egg or sperm). There is nothing that
a parent might have done to cause this condition, nor is there
anything that a parent could have done to prevent the error
from occurring.
3. What should I expect in the future for my child with dup
7q11.23 syndrome?
Every individual with dup 7q11.23 syndrome is unique and
it is impossible to know exactly what to expect. However, most
individuals with dup 7q11.23 syndrome have some degree of developmental
delay, primarily speech delay. In addition, many individuals
display some behaviors similar to those seen in patients with
autism spectrum disorders.
4. Does this mean that my child with
dup 7q11.23 syndrome will have autism?
No, but they might show some features such as anxiety,
difficulty with interpersonal skills, repetitive behaviors,
or other unusual behaviors. Only a detailed psychological evaluation
can determine whether your child has features that are consistent
with the diagnosis of autism or an autism-spectrum disorder.
5. Is there a cure for dup 7q11.23 syndrome?
Because the duplication of genetic material exists in every
cell of the body, there is no way to “cure” the
syndrome at present. However, physical / occupational / speech
therapy can help children overcome some of the developmental
delays. In addition, your primary physician may recommend additional
treatments for other aspects of your child’s individual
condition.
6. Are other family members at risk for having a child with
dup 7q11.23 syndrome?
This question can only be answered by your geneticist or
genetic counselor. In most cases, dup 7q11.23 syndrome occurs
only in the affected child and there is a very low risk of
recurrence in the family. However, in a fraction of cases (perhaps
10%) an otherwise unaffected parent is found to be a carrier
of the duplication. In this case, the recurrence risk would
be higher and the parents should receive detailed genetic counseling.
As with many genetic syndromes, we recommend for parents to
be tested for their child’s duplication in order to provide
the most accurate recurrence risk counseling.
7. Where can I get more information about dup 7q11.23 syndrome?
Since this syndrome has only recently been described, physicians
are still in the process of learning about it. If you would
like to share information with your primary physician, we
will provide a copy of our recent paper on request. Joining the
family support network is also a great way to share information
and ideas.
