For You and Your Healthcare Professionals
We often receive questions about the genetics of Fragile X, which is a complex topic! Fragile X is a group of conditions associated with alterations in the FMR1 gene, particularly in the number of CGG repeats. These alterations affect how the gene functions and identify the risk for Fragile X-associated conditions.
To help make sense of these complexities, we’ve developed a series of handouts covering a range of topics, including one specifically designed for healthcare professionals.

For Professionals

We want to express our appreciation to Melanie Nettler, a genetic counseling student intern, for her assistance in creating the various flyers on the genetics of Fragile X. Melanie worked closely with the NFXF to develop educational resources that help clarify the complexities of FMR1 Fragile X genetics.
