伴身材矮小症与性发育异常疾病的研究进展

Research Progress on Short Stature Accompanied by Disorders of Sex Development

  • 摘要: 身材矮小症(short stature,SS)与性发育异常(disorders of sex development,DSD)是两类具有高度临床异质性且病因复杂的疾病。生长激素与性激素在调控骨骼及性腺发育的作用通路方面存在一定相互作用和影响,可导致SS与DSD伴随发生,如Turner综合征、混合性性腺发育不良、Noonan综合征、Prader-Willi综合征等疾病。此类患者往往合并特殊面容、内分泌与代谢紊乱、心血管疾病等其他系统并发症,遗传因素涉及染色体数目与结构异常,SHOX、CHD7、SOX8、PTPN11等基因突变,RAS/丝裂原活化蛋白激酶信号通路异常及印记基因缺陷等。本文旨在系统梳理相关研究进展,以期为伴SS与DSD患者的临床诊疗策略提供参考依据。

     

    Abstract: Short stature (SS) and disorder of sex development (DSD) are two types of conditions char- acterized by high clinical heterogeneity and complex etiology. There is interplay and mutual influence between the pathways regulated by growth hormone and sex hormones in skeletal and gonadal development. Causing co- occurrence of SS and DSD, as seen in conditions such as Turner syndrome, mixed gonadal dysgenesis, Noonan syndrome, and Prader-Willi syndrome. Patients with these disorders are often accompanied by distinctive facial features, endocrine and metabolic disturbances, cardiovascular disease, and other systemic complications. Ge- netic factors involved include chromosomal numerical and structural abnormalities; mutations in genes such as SHOX, CHD7, SOX8, and PTPN11, dysregulation of the RAS/mitogen activated protein kinase signaling pathway, and defects in imprinted genes. This article aims to systematically review the relevant research pro- gress, in order to provide a reference for the clinical diagnosis and treatment strategies of patients with coexis- ting SS and DSD.
