diagnostic test for fragile x syndrome
What is fragile testing?
DNA studies are used to test for fragile X syndrome.
Genotypes of individuals with symptoms of FXS and individuals at risk for carrying the mutation can be determined by examining the size of the trinucleotide repeat segment and the methylation status of the FMR1 gene.Many of the FXTAS symptoms, such as memory problems and balance problems, may also be seen as natural parts of aging.
A healthcare provider may use a combination of a blood test, symptoms, and information from brain imaging, such as magnetic resonance imaging (MRI), to confirm a FXTAS diagnosis.
What is FMR blood test?
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.
