| 摘 要： | 目的 探讨中国人Van der Woude综合征（VWS）的临床表型及遗传学特点。方法 先证者法收集14个VWS家系并进行口腔专科检查、家系调查及基因突变分析,分析不同VWS家系个体或同一家系不同个体的临床表型,绘制家系图谱,明确遗传方式及致病基因,计算表型分布频率和表型基因频率。结果 VWS家系基本符合常染色体显性遗传特征,患者多数表现为典型的VWS,致病基因为干扰素调节因子6（IRF6）。VWS表型分布频率为：唇瘘91.9%,唇腭裂73.0%,牙畸形8.1%。不同家系个体和同一家系的不同个体临床表型存在明显差异。结论 收集的家系均为常染色体显性遗传,表现度变异大。中国人群VWS致病基因为IRF6,为Ⅰ型VWS。

| Abstract: | Objective This study aimed to investigate the clinical phenotype and genetic characteristics of Chinese families with Van der Woude syndrome (VWS).Methods Clinical manifestations between 14 families and within each family were recorded. Possible inheritance modes and pathogenic genes were analyzed. Phenotypic distribution and gene frequencies were calculated.Results Of the pedigrees investigated, an autosomal dominant inheritance pattern was suggested. All patients had typical symptoms. The pathogenic gene was interferon regulatory factor 6 (IRF6). Phenotypic distribution frequencies were as follows: lip pits (91.9%), cleft lip and/or palate (73.0%), and hyperdontia (8.1%). There were significant differences in clinical phenotypes among individuals of different families and individuals of the same family.Conclusion VWS in a Chinesepopulation was dominantly inherited with high penetrance and variable expressivity. The pathogenic gene was IRF6. VWS in a Chinese population was genotyped as VWS1. |
