[Primary familial and congenital polycythemia caused by EPOR gene mutation: two cases report and literature review].

Le résumé fourni par la source

In this paper, two cases of primary familial and congenital polycythemia (PFCP) were reported, and the literature was reviewed. PFCP is a rare autosomal dominant inherited disease caused by a gain-of-function mutation in the EPOR gene, resulting in a loss of negative regulation of erythrocyte proliferation. The two patients were young women with simple polycythemia and clear family history, and identified to carry the truncated mutation c.1316G>A (p.W439*) of EPOR gene. At present, there is no unified treatment plan for PFCP. Currently, there is no standardized treatment for PFCP; management primarily aligns with guidelines for polycythemia vera, focusing on preventing thrombotic complications. This article discusses the clinical features of PFCP, EPOR gene mutations, and their pathogenic mechanisms, while providing diagnostic and therapeutic recommendations based on existing literature.
