Reading and phonological skills in boys with fragile X syndrome.
Boys with fragile X can read at mental-age level if you shore up their weak phonological awareness.
01Research in Context
What this study did
Klusek et al. (2015) tested boys with fragile X syndrome. They looked at reading scores and phonological skills.
The team compared the boys’ reading to their mental age. They also checked if phonological awareness predicted reading success.
What they found
Reading scores matched mental-age level. Phonological skills were weak.
Stronger phonological awareness linked to better reading.
How this fits with other research
Ganz et al. (2009) surveyed parents and saw reading stay weak into adulthood. The new study shows the weak link is phonology, not low mental age.
Hoyle et al. (2022) found language drives narrative skill in FXS teens. Together, the papers say: train language and phonology early to lift later literacy.
Astrea et al. (2015) saw boys with Duchenne muscular dystrophy show mild dyslexia-like phonology gaps. FXS boys had similar gaps yet kept mental-age reading, showing FXS can hit reading potential when phonology is supported.
Why it matters
You can aim reading lessons at mental-age books. Add quick phonological warm-ups like rhyming or sound-blending. These small drills may unlock grade-level text for boys with FXS.

03Original abstract
Although reading skills are critical for the success of individuals with intellectual disabilities, literacy has received little attention in fragile X syndrome (FXS). This study examined the literacy profile of FXS. Boys with FXS (n = 51; mean age 10.2 years) and mental age-matched boys with typical development (n = 35) participated in standardized assessments of reading and phonological skills. Phonological skills were impaired in FXS, while reading was on-par with that of controls. Phonological awareness predicted reading ability and ASD severity predicted poorer phonological abilities in FXS. Boys with FXS are capable of attaining reading skills that are commensurate with developmental level and phonological awareness skills may play a critical role in reading achievement in FXS.
