What is Southern blotting for fragile X?
Southern blot analysis is the method of choice for identifying full mutations and large premutations and determining if the gene is methylated while PCR analysis allows accurate determination of CGG repeat number for normal, grey zone and premutation alleles.
How to interpret fragile X results?
What Do My Test Results Mean?
1If you have results in the normal (i.e., typical) range, you are not at risk to have a child with Fragile X syndrome.2If you have an intermediate (i.e., “gray zone”) result, you are not at risk to have a child with Fragile X syndrome.
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.
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.
