Iron overload can lead to chronic complications, serious organ dysfunction or death in the body. Under hypoxic conditions, the body needs more iron to produce red blood cells to adapt to the hypoxic environment. The prevalence of iron overload in the Tibetan population is higher than that in the Han population. To explore the molecular mechanism of iron-overload in the Tibetan population, this study investigated the transcriptome of the Tibetan iron overload population to obtain differentially expressed genes (DEGs) between the iron-overloaded population and the normal iron population. Functional enrichment analysis identified key related pathways, gene modules and coexpression networks under iron-overload conditions, and the 4 genes screened out have the potential to become target genes for studying the development of iron overload. A total of 28 pathways were screened to be closely related to the occurrence and development of iron overload, showing that iron overload is extremely related to erythrocyte homeostasis, cell cycle, oxidative phosphorylation, immunity, and transcriptional repression.
