LDHC and food allergy: Table 5 demonstrates that methylation profiles of LDHC and SLC35G2 effectively discriminate food allergy, resolved cases, and healthy controls. Among the models tested, Random Forest and SVM-RBF achieved the highest accuracy, while other approaches also provided consistent results. These findings indicate that the proposed epigenetic markers are robust across datasets and highlight their potential clinical utility as diagnostic biomarkers. Figure 8 shows the PPI analysis graph.
