Tip of Chromosome 9
Name: Ewa D.
Date: December 2002
A parent of a child client has been told that his
daughter (presently 13) is missing the tips of chromosome 9. I am a
social worker. Please explain 1) the function of that chromosome as well
as 2) the implications of these tips missing. Specifically, what are the
symptoms of this as well as would the effects be seen behaviorally,
intellectually and/or socially?
A family with questions about a chromosome abnormality should be referred
for genetic counseling.
There they will have confirmation (or otherwise) of the missing piece of
genetic material and its precise location and extent. If the father is
correct about his daughter's chromosomes, it suggests that chromosome
studies have already been done. These should always be accompanied by
genetic counseling to communicate the results, and their implications for
the child, in a way the family can understand.
A genetic counselor will help answer the questions you are asking about the
symptoms, the function of the chromosome involved, and the behavioral,
intellectual and social effects.
If the parents have already met with a genetic counselor but still feel
uncertain, they would be welcome to return for a follow-up visit to review
the information and learn about new research discoveries.
As a social worker you would be welcome at the genetic counseling
appointment if the family want you there - then you could hear it all
yourself and be well equipped to help them deal with it in the future. Or
you could arrange to receive a copy of the genetic counselor's dictation
letter describing the appointment and summarizing the information discussed.
