Abstract
Introduction: McLeod syndrome (MLS) is a rare X-linked recessive disorder affecting multiple systems. Herein, we present the clinical symptoms, laboratory diagnostic results, and genetic characteristics of a patient with MLS caused by a novel c.459_460insC variation in the XK gene. Case Presentation: A 58-year-old male Chinese patient presented with neurological symptoms, seeking belated medical attention at the hospital. Numerous laboratory tests indicated a high likelihood of MLS, featuring chronic granulomatosis and neuroacanthocytosis. The patient’s blood samples were sent to the Blood Center of Zhejiang Province, China, for further analysis. Sequencing analysis revealed a novel hemizygous c.459_460insC variation in exon 2 of the XK gene. Therefore, we identified a patient with MLS possessing a novel genetic variation (GenBank Accession No. OQ473658). Conclusion: Our findings elucidate a novel c.459_460insC variation associated with MLS, resulting in a frameshift and premature stop codon (p.Leu154Profs*45). The clinical manifestations, laboratory examination, and XK gene analysis in this case will aid in diagnosing MLS in future patients.
期刊介绍:
This journal is devoted to all areas of transfusion medicine. These include the quality and security of blood products, therapy with blood components and plasma derivatives, transfusion-related questions in transplantation, stem cell manipulation, therapeutic and diagnostic problems of homeostasis, immuno-hematological investigations, and legal aspects of the production of blood products as well as hemotherapy. Both comprehensive reviews and primary publications that detail the newest work in transfusion medicine and hemotherapy promote the international exchange of knowledge within these disciplines. Consistent with this goal, continuing clinical education is also specifically addressed.
