ABSTRACT
<p><b>OBJECTIVE</b>To use array comparative genomic hybridization (array-CGH) and multiplex ligation-dependent probe amplification (MLPA) to detect unbalanced rearrangements in 4 cases suspected to have chromosome disease but were undetected with conventional karyotype analysis, and to assess the applicability of array-CGH and MLPA for detection of unbalanced translocation.</p><p><b>METHODS</b>Genomic DNA was extracted with standard procedures. All cases were analyzed by array-CGH and subtelomeric MLPA.</p><p><b>RESULTS</b>All of the cases were identified to have unbalanced translocations by array-CGH analysis, among which 3 were consistent with subtelomeric MLPA analysis. For the remaining one, its chromosomal abnormality was not detected by MLPA as the imbalance has occurred outside of target regions.</p><p><b>CONCLUSION</b>Both array-CGH and MLPA techniques can complement conventional karyotyping for detecting unbalanced translocations. The combination features both high resolution and efficiency for clinical use.</p>
