Detection of RB1 Gene Copy Number Variations Using a Multiplex Ligation-Dependent Probe Amplification Method.

Abstract

Multiplex ligation-dependent probe amplification (MLPA) is based on simultaneous multiplex PCR of specific probes that hybridize to multiple different target DNA regions. The method can identify copy number changes, gross gene rearrangements, methylation patterns or even point mutations. MLPA has been a reliable approach to identify copy number changes in the clinical and research settings and is widely used for the screening and investigation of copy number variations and genomic aberrations of interest in various diseases. In this chapter the analysis of the copy number changes in the RB1 gene locus by MLPA is described.
