What is fragile X syndrome diagnostic and carrier testing?
The fragile X carrier test provides specific information about whether or not individuals are fragile X carriers, and about their risks of having a child with fragile X syndrome. The test is performed on a small sample of blood. Results are usually available within two weeks.
How do you test for fragile X carrier?
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.
What is the best confirmatory test for fragile X syndrome full mutation?
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.
Fragile X syndrome: DNA is amplified by the polymerase chain reaction (PCR) to determine the size of the CGG repeat region within the FMR1 gene. PCR products are generated using a fluorescence labeled primer and sized by capillary gel electrophoresis.
