Laboratory assay overview
This test is to be used in the prenatal diagnosis of Fragile X (FX) syndrome in pregnancies where the mothers are identified carriers of gray zone (45-54), permutation (55-200), or full-mutation (>200) CGG repeat alleles. It can also be used in the prenatal diagnosis of fetuses whose siblings are affected with FX.
