What is the typical IQ range for a child diagnosed with Fragile X syndrome?

Children diagnosed with Fragile X syndrome typically present with a wide range of intellectual abilities; however, the most common finding is that many have an IQ that falls in the range of 55 to 70. This places them in the category of intellectual disability. Fragile X syndrome is the most prevalent inherited cause of intellectual disability, and the cognitive impairments associated with it often manifest as learning disabilities and developmental delays. The IQ distribution in Fragile X can vary significantly, yet the majority of affected individuals are often found to have scores that fall below 70, reflecting varying degrees of cognitive challenges.

While some children may have an IQ within the normal range or even above average, those cases are less frequent. It's important for assessments to look at individual capabilities, but statistically, the lower IQ range reflects the general trend associated with this syndrome.
