Obstructive sleep apnoea (OSA) research accelerates dramatically in 2025, propelled by bioinformatics unraveling endotypes, comorbidity deep dives, and multidisciplinary clinics achieving superior outcomes, as synthesized in a Frontiers in Medicine editorial charting the field’s precision medicine trajectory. These developments promise to transform the billion-person global burden.
Bioinformatics Revolution: From Genomics to Phenomics
Single-cell/nucleus RNA-seq identifies 6 OSA endotypes: M1 macrophage inflammatory hub (IL6/36 +3.2logFC), fibroblast ECM stiffening (COL1A1 hub), adipocyte leptin resistance (LEPR -2.1), neuromuscular (RUNX3 +1.8), endothelial HIF1A cascade, B-cell autoimmunity. Bulk RNA 1,042 OSA vs controls yields 2,847 DEGs; WGCNA turquoise module (hypoxia core) predicts AHI 38% variance (R=0.62). GWAS meta 50 loci (PAX8 thyroid-cancer bridge, BMI-adjusted rs111000565 OR 1.42). Epigenome-wide 217 CpG sites (SHOX2 methylation AHI r=0.71); multi-omics machine learning endotype classifier AUC 0.94.
