Molecular analysis of patients suspected of Fragile X Syndrome

The PCR-P method was named so because of its committed amplification of fragments up to ~330 CGG repeats (full mutation of low expansion) in male patients, and fragments of up to ~160 CGG (pre-mutation) in females. These results are considered to be very satisfactory for the diagnosis of FXS. This i ...
