Developmental and behavioral pediatricians' attitudes toward screening for fragile X.
Most DBPs want every newborn tested for fragile-X, yet they admit they need more genetics training to counsel families well.
01Research in Context
What this study did
Acharya et al. (2013) asked developmental-behavioral pediatricians how they feel about newborn screening for fragile-X syndrome. The team mailed a short survey to DBPs across the United States. Doctors answered yes-or-no questions and rated their own knowledge of the condition.
What they found
Most doctors liked the idea of testing every baby for fragile-X. At the same time, most admitted they did not fully understand the range of problems the test can uncover. Support was high, but confidence in their own genetics know-how was low.
How this fits with other research
Finucane et al. (2013) ran a nearly identical survey the same year. They asked autism clinicians instead of DBPs and got the same result: people want FXS data but lack FXS facts. The two papers act as conceptual replications, showing the knowledge gap is wide across professions.
Scott et al. (2026) picked up the story where the 2013 survey left off. They followed families whose newborns actually screened positive. Only half of those babies were in early-intervention programs by age one. The later study extends the DBP survey by revealing that good intentions do not automatically turn into speedy services.
Dougherty et al. (1994) took the opposite path. They screened only children who already looked high-risk and still found FXS at solid rates. That earlier work reminds us that targeted testing can work, yet today’s doctors lean toward universal screens.
Why it matters
If universal fragile-X screening becomes routine, BCBAs will see more infants with a positive result on your caseload. Expect referrals before delays show up, and be ready to explain to families why therapy can help even when the baby looks typical. Use the DBP survey as a cue to build your own FXS knowledge: know the motor and language red flags, link families to genetics counselors, and track Part C paperwork early so the 50% enrollment gap found by Scott et al. (2026) does not happen on your watch.

03Original abstract
Developmental and behavioral pediatricians (DBP) diagnose and care for children with fragile X syndrome. Their attitudes toward FMR1 newborn screening (NBS) and FMR1 carrier testing in childhood could highlight potential pitfalls with FMR1 NBS. We conducted a cross-sectional survey with an adjusted response rate of 61%. Among DBP, 74% supported universal FMR1 NBS, preferring to identify both full mutations and premutations. DBP also support FMR1 testing of asymptomatic siblings. Although DBP support testing for premutations at various points in the lifespan, DBP are not familiar with the array of fragile X-associated disorders (FXAD). Targeted educational interventions are needed to ensure that all health care providers have the knowledge and competence to consent and to counsel families on FXAD.
