摘要: 目的:对一例散发的伴丘疹损害的先天性无毛症(APL)患儿进行Hairless(HR)基因突变检测。方法:提取患儿及其表型正常父母的血液样本DNA,采用Sanger测序法检测APL患儿HR基因突变。结果:测序结果显示患儿HR基因存在复合杂合突变,分别为位于第10号外显子的新的移码突变c.2270delC和位于第15号外显子内的新的错义突变c.3038 T>C。以上两种突变在100名健康对照中均未发现。结论:在该患者中检测到了HR基因的突变,其产物无毛蛋白的缺失或者功能减退可能是导致该患者发病的原因。

Abstract: Objective: To detect the Hairless (HR) gene mutation in one child affected with atrichia with papular lesions (APL). Methods: DNA was extracted from the child and her unaffected parents. HR gene mutations were detected by Sanger sequencing. Results: Compound heterozygous mutations of  HR gene were identified in the patient, including a novel frame shift mutation in exon 10, c.2270delC, and a novel missense mutation in exon 15, c.3038 T>C. Both of the mutations were not found in 100 unrelated controls. Conclusion: The HR mutations may result in the loss of  HR protein function, leading to APL.
