%X Abstract: To explore the feasibility and accuracy of MLPA-based array (Array-MLPA) in detecting sex chromosome ab-normalities, MLPA probes were designed to target against three gene loci, TSPY (p11.2), PRY (q11), and RBMY (q11.2) in human Y chromosome. Array-MLPA approach was applied to test abnormalities of Y chromosome in 15 patient samples with known karyotypes. The data were compared with karyotyping and PCR analyses. The results showed that the copy number of each site detected by Array-MLPA was basically consistent with karyotyping analysis. Moreover, small deletions of chromosomes that were not found by routine karyotyping analysis were identified by the approach described, which fully agreed with PCR analysis, indicating that Array-MLPA was able to detect small abnormalities of chromosomes that cannot be found by karyotyping analysis. Compared to the routine karyotyping method, Array-MLPA has the advantages of high efficiency and reliability in chromosomal analysis, which has great potential in clinical application of diagnosis of chromo-some abnormalities.
