There is significant variability in how FXS affects development in individuals.
Families have a range of options to consider.
If you suspect that a child has fragile X syndrome, confirm the diagnosis with genetic testing. For an accurate diagnosis, seek DNA testing at a pediatric genetics clinic. Licensed genetic counselors at the clinic will provide information about risks for other family members and provide support during the process of informing extended family members of the need for testing. Find a pediatric genetics clinic by calling the nearest university hospital or child development clinic. Schedule a developmental evaluation as quickly as possible when concerns arise.
