Abstract:
BACKGROUND: Haemophagocytic lymphohistiocytosis (HLH) is a syndrome that occurs in patients with severe systemic hyperinflammation. GATA binding protein 2 (GATA2) is a transcription factor and key component in haematopoiesis and stem cell biology.
METHODS: Three patients with HLH, one with Mycobacterium avium infection, one with Epstein-Barr virus (EBV) infection, and one with Mycobacterium kansasii infection, were all subsequently found to have a defect in the GATA2 gene through genetic testing.
CONCLUSIONS: GATA2 deficiency syndrome should be considered in patients with myelodysplastic syndrome, nontuberculous mycobacterium infection and HLH. In addition, the GATA2 gene variant may be a genetic defect that could be the cause of the primary HLH. However, further studies are needed to confirm the role of GATA2 pathogenic variants in the pathogenesis of HLH.
摘要:
背景:噬血细胞性淋巴组织细胞增生症(HLH)是一种发生在严重全身性炎症患者中的综合征。GATA结合蛋白2(GATA2)是造血和干细胞生物学中的转录因子和关键成分。
方法:三例HLH患者,一个是鸟分枝杆菌感染,一个是EB病毒(EBV)感染,还有一个感染了Kansasii分枝杆菌,随后通过基因检测发现GATA2基因存在缺陷。
结论:骨髓增生异常综合征患者应考虑GATA2缺乏综合征,非结核分枝杆菌感染和HLH。此外,GATA2基因变异可能是一种遗传缺陷,可能是原发性HLH的原因。然而,需要进一步的研究来证实GATA2致病变异体在HLH发病机制中的作用。
