Furthermore, MLPA confirmed abnormalities in several oncogenes, including CDKN2A/B, EBF1, ERG, ETV6, IKZF1, JAK2, and PAX5.<h4>Conclusion</h4>This study demonstrates the utility of combined SNP 6.0 microarray and MLPA in providing a comprehensive and refined understanding of the genetic landscape of BCP-ALL in the Malaysian population. This evidence concerns the gene CDKN2A and acute lymphoblastic leukemia.
