Test Overview
MLPA probes hybridize to target regions of the TP53 gene and are amplified by multiplex PCR. The amplification products are analyzed by capillary electrophoresis and copy numbers for these TP53 target regions are generated.
Analysis for the presence of TP53 (OMIM:191170) deletions or duplications in patients with a phenotype consistent with Li-Fraumeni syndrome (LFS) (OMIM:151623) or Li-Fraumeni-like syndrome (LFL).
