Genetics Disorder Fragile X
By: Tyler Weaks
Everyone that is diagnosed with Fragile X doesn't have the same signs and symptoms, or to the same degree. Affected children in the same family can even have different symptoms. These differences often make Fragile X hard to diagnose. However, because everyone with Fragile X has too little FMRP, they do share a pattern of certain physical, social, mental, and sensory characteristics.
In general, the signs and symptoms of Fragile X fall into five categories:
- Intelligence and learning
- Social and emotional
- Speech and language
- Disorders commonly associated or sharing features with Fragile X
Most people with Fragile X have impaired intellectual functioning, which affects their ability to think, reason, and learn.

How the disease is diagnosed
In most cases, scientists use an intelligence test to measure intellectual functioning, resulting in an IQ (intelligence quotient) score. This score also reflects many things besides the ability to think. Attention disorders, hyperactivity, anxiety, and language processing problems can interfere with test-taking skills and learning.
Researchers consider people who score between 85 and 115 on an IQ test to have "average" intelligence. On the whole, less than 20% of males with Fragile X have an IQ in this range. At the same time, few people with Fragile X are severely or profoundly impaired, with IQs below 40 or 25, respectively. In general, those with a full mutation tend to have an IQ somewhere in between 40 and 85, which is considered mild to moderate mental impairment.
