Study Notes
Fragile X Syndrome
- Caused by a mutation in the FMR1 gene (fragile X mental retardation 1)
- Normally, the FMR1 gene produces a protein essential for brain development.
- A defect in this gene results in insufficient or no protein production.
- Characterized by:
- Mental retardation
- Large ears
- Prominent jaw
- Pale blue irises
- Boys are more severely affected due to having only one X chromosome. A single fragile X gene on the single X chromosome is likely to have a more significant impact.
