| 摘 要： | 目的:分析外胚叶发育不全家系的表型特点和遗传特征,并对家系基因型进行分析。方法:收集1个外胚叶发育不全家系,采用临床检查和家系调查的方法,调查并记录先证者及家系成员的病史和体格检查资料。对家系成员EDAR基因开放阅读框内外显子编码区及外显子-内含子接头区核苷酸序列进行分析。结果:收集到的家系为常染色体显性遗传,患者临床表现典型,家系内表现度差异小。家系成员EDAR基因开放阅读框内未检测到基因突变。结论:本研究收集的外胚叶发育不全家系临床症状明显,致病基因排除EDAR基因。

| Abstract: | Objective: To analyze the phenotype, genotype and genetic characters of ectodermal dysplasia pedigree. Methods: The ectodermal dysplasia pedigree was reported through the identified proband. All family members were interviewed and had comprehensive clinical examination. The nucleotide sequence in open reading frame of EDRA gene was studied by direct sequencing. Results: The pedigree was transmitted through autosomal dominant manner. Patients had characteristic features of ectodermal dysplasia. There was no mutation in EDAR gene. Conclusion: This family showed typical phenotype of ectodermal dysplasia. The EDAR gene was excluded for the causative gene. |
