The LPMD algorithm effectively captured DNMT3A mutation-associated epigenetic instability (Cohen's d = 0.8, p < 0.001), with the strongest effects observed in the 5'UTR-Exon1 region (d = 0.74) and a gradient pattern from CpG islands to shores (d: 0.59→0.54→0.43). The 5-DMDR panel offers a practical tool for azacitidine response prediction, while dynamic LPMD monitoring provides a potential biomarker for therapeutic guidance. These findings establish methylation disorder as a clinically actionable dimension of epigenetic dysregulation in myeloid malignancies.
