GATA2 deficiency: a mystery myelodysplasia

Abstract

SummaryGATA2 deficiency, arising from mutations in the GATA2 gene, is a rare genetic disorder with profound implications for hematopoiesis, immune function, and overall health. This case report provides a comprehensive exploration of the clinical manifestations, diagnostic challenges, and management of GATA2 deficiency, emphasizing the importance of early recognition and specialized care. A 55-year-old female presented with a complex clinical presentation that evolved from myalgias into a syndrome of symptoms, including fever, chest pain, dyspnea, and profound weakness. The diagnostic journey involved recurrent admissions, a delay in diagnosis, and the consideration of various differential diagnoses, reflecting the elusive nature of GATA2 deficiency. Pulmonary involvement, hematologic abnormalities, and the patient’s transfer to a specialized center further highlighted the multifaceted aspects of this disorder. This case underscores the diagnostic challenges and clinical heterogeneity of GATA2 deficiency. It emphasizes the need for a high index of suspicion, early diagnosis, and specialized care. The elusive nature of the disorder, pulmonary involvement, and the emergence of hematologic abnormalities exemplify the complexity of GATA2 deficiency. The case report advocates for enhanced awareness, early detection, and the importance of specialized expertise in managing this rare genetic condition.
