Attendance at Fragile X Specialty Clinics: Facilitators and Barriers.

Bao et al. (2017) asked why some families with Fragile X syndrome (FXS) show up at specialty clinics and others do not. They used the big National Fragile X Survey. Parents answered questions about income, education, child age, and other diagnoses.

The team ran numbers to see which facts best predicted who had visited an FX clinic at least once.

Guardian education, household income, and simply knowing the clinic exists were the strongest predictors. Older kids and those with extra diagnoses like autism also went more often.

Severity of Fragile X symptoms by itself did not drive attendance. Money and awareness mattered more.

Anonymous (2017) is the same survey set, so it repeats these exact numbers. The match gives us confidence in the pattern.

Scott et al. (2026) extends the story to babies. Only half of infants with FXS were enrolled in Part C by age one, even though they were eligible. Together the papers show the same barrier at two life stages: knowledge and paperwork, not need.

Knight et al. (2019) looked at autism clinics instead of FX clinics. Travel distance, older child age, and minority status also cut attendance there. The same social forces pop up across diagnoses.

Carmichael et al. (1999) is the older voice. Back then, families said they felt lost right after diagnosis. The 2017 data now quantify that same feeling: lack of clear info still keeps families away decades later.

If you work with FXS families, do not assume the most affected kids are already in care. Check if caregivers know the clinic is open to them, if they can afford time off, and if forms are in plain language. A quick phone call or visual map can turn "eligible" into "attending."
