摘要: 目的应用基因诊断方法进一步提高对儿童先天性粒细胞减少症(CN) 的认识和诊断水平。方法以1例
患者为研究对象,收集其临床资料、实验室检查结果,按序检测ELA2、GFI1、HAX1及WASp致病基因突变情况。
依上述步骤对患儿分别进行疾病的临床及基因诊断并随访。结果参照诊断标准该患儿诊断为无遗传背景的散发性非
;基因检测显示其携带已经报道的ELA2基因突变:>A;此外患儿中性粒细胞表面G-CSFR表达正常,
G-CSFR胞内段未发现获得性截短性突变。结论为ELA2基因突变所致,为该患儿未来的
分组临床研究及基因治疗提供依据。[临床儿科杂志,2013,31(1):44-47]

Abstract: Objective To improve the understanding and diagnosis of congenital neutropenia (CN) in children by the use
of gene mutation analysis. Methods Clinical data and laboratory results of a child suspected were collected. ELA2, GFI1,
HAX1, and WASp genes were sequenced. Clinical and ic diagnosis of the child was made according to the above ste
