Abstract:
Chronic mountain sickness (CMS) or Monge syndrome is a disease that is prevalent at altitude above 2 500 meters. High altitude polycythemia (HAPC) is one subtype of CMS. EPAS1 and EGNL1 are the most critical high-altitude adaptation genes in the genome of the Tibetan population. The HIF-PHD-VHL system plays an important role in the pathogenesis of HAPC. The protease encoded by the SENP1 gene regulates hypoxia related transcription factors such as HIF and GATA to affect the expression of EPO or EPOR involved in red blood cell generation. With the development of genetic testing and omics technology, new progress in the fields of metabolomics, proteomics and metabolomics has been made in the pathogenesis of HAPC. The above new research results provide a preliminary basis for bone marrow hematoecology and hematopoietic regulation of HAPC. The diagnostic criteria for CMS have certain limitations, especially in patients with excessive erythrocytosis who should undergo genetic testing recommended for congenital and polycythemia vera. This article provides a review of the latest research on HAPC in various omics techniques, hematopoietic regulation and diagnostic processes which is more conducive to understand the pathogenesis. The clinical diagnosis of excessive erythrocytosis emphasizes the importance of genetic testing.
