1IntroductionThis Handbook gives basic information, in plain
language, about understanding and coping with a
serious disorder known as Fanconi anemia, or FA.
The initial FA diagnosis is always a shock. Once it has
been absorbed, families of FA patients and their
friends—and even physicians—may search for months
for trustworthy information. Families also react
emotionally to the grim prognosis. They feel
understandable anger, denial, grief, unfounded guilt
or withdrawal. As parents of FA children, we personally
know each of these reactions.
This Handbook answers common questions in simple
terms. We include more technical information in a
number of appendices. We are deeply grateful for the
experience of researchers, treating physicians and
other families in our worldwide support group.
Many medical words—especially those with Latin and
Greek origins—confuse families. Complicated words
may be a real barrier to your understanding of FA and
your discussions with your doctors. Our text defines
many confusing terms. We also include a glossary of
medical and scientific terms you may see or hear (Appen-
dix Y). Words in
bold type are defined in this glossary.
This Handbook is the result of many hours of research
and consultation, and years of experience. It is written
for lay people by lay people. We are not doctors, but we
follow progress in FA-related science on a daily basis.
All medical information included here should always be
reviewed with your own treating physician. If you have
2Fanconi Anemia: A Handbook for Familiesquestions relating to treatment or prognosis, please raise
these issues with your doctor or with an appropriate
specialist. The Fanconi Anemia Research Fund recently
published
Fanconi Anemia: Standards for Clinical
Care, a handbook for treating physicians. Copies are
available from the FARF office.
Do not be surprised if world-famous experts disagree.
You may read or hear conflicting medical advice. That
problem is common even with well-known illnesses.
But FA is a rare orphan disease. The biological
processes that threaten FA patients are poorly
understood. Doctors should welcome your questions.
Many might encourage you to get a second opinion.
We know how serious this disorder is. FA has claimed
too many lives. We make no exaggerated promises, and
we create no false hopes of instant cure. But progress in
medical science relating to FA has been very rapid and
encouraging in the last decade. Even as we write, new
developments in genetic research and improved
therapies may make our information out of date.
We welcome that progress in every way.
This Handbook is dedicated to the memory of special
children and young adults—claimed by FA so unfairly
before reaching their full potential. We also dedicate this
manual to the physicians and researchers who are work-
ing to understand, treat, and cure this hateful affliction.
We hope that this Handbook helps you in your own
family struggle. Join us, if you can, in active efforts to
seek effective treatments, to obtain funding for medical
research, and to find a cure.
