Purpose:
To develop a high resolution microarray based method to detect single- and multiexons gene deletions and duplications.
Methods:
We have developed a high-resolution comparative genomic hybridization array to detect single- and multiexon deletions and duplications in a large set of genes on a single microarray, using the NimbleGen 385K array with an exon-centric design.
Results:
We have successfully developed, validated, and implemented a targeted gene comparative genomic hybridization arrays for detecting single- and multiexon deletions and duplication in autosomal and X-linked disease-associated genes.
Conclusion:
The comparative genomic hybridization arrays can be adopted readily by clinical molecular diagnostic laboratories as a rapid, cost-effective, highly sensitive, and accurate approach for the detection of single- and multiexon deletions or duplications, particularly in cases where direct sequencing fails to identify a mutation.
