We are excited to share journal publications like this one resulting from FORWARD data. There are many more papers currently in development, and the future for Fragile X syndrome research is bright as more data is gathered.
The Association Between Mosaicism Type and Cognitive and Behavioral Functioning Among Males with Fragile X Syndrome
This study looked at mosaicism in males with Fragile X syndrome. Most males with FXS make very little or no amount of a protein, called FMR1, that is important for brain development. This happens because the gene that makes this protein has been “turned off” in all of the cells in their body by a process called methylation. However, some males with FXS have what is called “methylation mosaicism” which means that some, though not all, of their cells have a gene that has not been turned off by methylation and can still make the FMR1 protein.
In this study, participants with methylation mosaicism tended to have less severe intellectual disability and better social and functional skills. More research needs to be done, but knowing more about how FXS differs in people with and without methylation mosaicism may eventually help guide expectations and treatment of individuals with FXS.

About the FORWARD Registry & Database
FORWARD is made possible by all the participating families sharing their life experiences for research. By giving families, doctors, scientific researchers, and policymakers an inside look into how Fragile X syndrome presents itself across the human lifespan, you’re involvement is a huge contribution toward more positive health outcomes and better care and services for future generations.

Latent Class Analysis Identifies Distinctive Behavioral Subtypes in Children with Fragile X Syndrome
FORWARD // Among the different models resulting from the latent class analysis, a 5-class solution yielded the most clinically meaningful pharmacotherapy-independent behavioral subtypes.
Examination of Correlates to Health-Related Quality of Life in Individuals with Fragile X Syndrome
FORWARD // We examined the nature and degree of association between health-related quality of life and established measures of functioning in FXS; 155 parents completed the questionnaires on their child as part of the larger CDC-funded FORWARD study.
