What is the molecular technique of choice to diagnose fragile X syndrome?
Southern blot, which allows mutations to be detected and methylation status to be determined in a single test, remains the procedure of choice for most laboratories.What are the methods of diagnosis for fragile X syndrome?
FXS can be diagnosed by testing a person's DNA from a blood test. A doctor or genetic counselor can order the test. Testing also can be done to find changes in the FMR1 gene that can lead to fragile X-associated disorders.What are the molecular features of fragile X syndrome?
In patients with fragile X syndrome, the expanded CGG triplet repeats are hypermethylated and the expression of the FMR1 gene is repressed, which leads to the absence of FMR1 protein (FMRP) and subsequent mental retardation. FMRP is an RNA-binding protein that shuttles between the nucleus and cytoplasm.- A DNA test, the Fragile X mental retardation (FMR-1) gene test, was introduced in 1991. This test is the most accurate one (99+ percent) for detecting Fragile X Syndrome. The chromosome test is still available through most labs and is used for a variety of diagnostic purposes.
