摘要
本文回顾分析1例经基因检测明确诊断的施-戴综合征(Shwachman-Diamond综合征,SDS)患儿的临床资料,并结合相关文献总结SDS的临床表现、基因特征及治疗。该患儿为3个月男婴,以反复肺部感染为首发临床表现,伴胰腺外分泌功能障碍(营养不良、发育落后)、肝功能异常及间断中性粒细胞减少。患儿全外显子测序提示SBDS基因exon2杂合缺失和c.258+2T>C半合子突变。因此,对于临床有病因不明的反复肝功能异常、中性粒细胞减少、感染,同时伴有生长发育落后的患儿,应及时进行基因检测以助于早期诊断。
The clinical data of a child with Sshwachman-Diamond syndrome(SDS)confirmed by genetic testing are reviewed and analyzed,and the clinical manifestations,genetic characteristics and treatment of SDS are summarized based on relevant literatures.This 3-month old boy presented with recurrent pulmonary infection as the first clinical presentation and accompanied with pancreatic exocrine dysfunction(malnutrition,stunted growth),abnormal liver function and intermittent neutropenia.Whole-exon sequencing revealed exon2 heterozygous SBDS gene deletion and c.258+2T>C hemizygous mutation.Therefore,timely genetic testing should be carried out to facilitate early diagnosis for children with recurrent abnormal liver function,neutropenia and infection of unknown etiology,accompanied by stunted growth.
