多发性骨性连接综合征大家系的临床观察及遗传学研究
Clinical and genetic study of a large pedigree of multiple synostoses syndrome
【摘要】 目的:探讨多发性骨性连接综合征(SYNS)大家系的临床及遗传特征。方法:采用家系分析法探讨SYNS大家系的遗传规律,采用全基因组扫描和连锁分析法定位该家系的致病基因。结果:排除由NOG和GDF5基因突变导致的SYNS1和SYNS2型,发现1个新的SYNS致病基因位点。结论:SYNS存在一种新的遗传异质性,该致病基因定位于13q12。
【Abstract】 Objective To study the clinical and genetic characteristics of a large pedigree of multiple synostoses syndrome(SYNS).Methods The genetic characteristics in this family was investigated by pedigree analysis.Genome-wide scan and linkage analysis were performed to localize the disease gene.Results SYNS1 and SYNS2 caused by NOG and GDF5 genes respectively were excluded and a new disease locus was defined.Conclusions A novel genetic heterogeneity of SYNS is found with the disease gene located at 13q12.
