摘　　要：目的 报告先天性无痛无汗症(CIPA)1例并文献复习,增加其病因及临床特点的了解,减少误诊误治。方法 采集2021年12月安徽省儿童医院收治的病儿及其父母外周血进行医学全外显子组基因检测,并对候选基因变异进行Sanger测序验证。结果 基因分子遗传学分析结果提示病儿在神经营养因子赖氨酸激酶受体1型(NTRK1)中存在2个分别来自父母双方的杂合突变(c.575-19G>A和c.444C>A),结合病儿临床表现符合CIPA。结论 CIPA为单基因遗传病,临床罕见,基因分子遗传学分析有助于诊断。Objective To report a case of congenital insensitivity to pain with anhidrosis(CIPA)and to review the literature to pro⁃mote the understanding of its etiology and clinical characteristics so as to reduce misdiagnosis and mistreatment.Methods The pe⁃ripheral blood of the patient admitted to Children's Hospital of Anhui Province in December 2021 and her parents was collected for medical whole-exome gene detection,and the candidate gene variants were verified by Sanger sequencing.Results The results of ge⁃netic and molecular genetic analysis showed that there were two heterozygous mutations(c.575-19G>A and c.444C>A)in the neuro⁃trophic factor lysine kinase receptor type 1(NTRK1)of the infant respectively from both parents.The clinical manifestations of the pa⁃tient was consistent with CIPA.Conclusion CIPA is a monogenic disease,which is rare in clinics.Molecular genetics testing is helpful for its diagnosis.
