项目摘要
We firstly thought DMBX1 is strong candidate which is located 2.6 Mb telomeric side of D1S2733. The STRP marker, D1S2733,is distal marker Engle et al., defined the cadidate locus. We found missnese mutation in one patient with congenital hereditary ptosis(CHP). We also found, however, this missense mutaiton in non-affected father and younger brother of the patients, DMBX1 gene would not likely to be causative gene for CHP.We changed our research aim to do linkage analysis in one large family to fined new locus for CHP. We used ABI Prism Linkage Mapping Set-MD10 in 15 members including 4 affected individuals. LOD score calculation was performed with MLINK software in FASTLINK ver.4.1P or Genehunter software. Six markers, D1S2697 (1p)、D1S255 (1p)、D1S484 (1q), D5S630 (5p), D7S669 (7q), and D14S276 (14q) showed relatively high LOD score indication possible linkage. We set another STRP markers around these markers to perform haplotype analysis. We found two regions, 1p35.3-36.1 and 14q21.1-23.2,are possible candidate loci, but we could not define to one region. Some members have possible mutant haplotype without CHP phenotype and suggest incomplete penetrance in this family. We would re-evaluate phnotypes of members in this family and perform linkage analysis of new family to confirm the candidate locus for CHP.
我们首先认为DMBX 1是D1 S2733的一个强有力的候选基因,它位于D1 S2733的2.6Mb端粒侧。STRP标记D1 S2733是Engle等人的远端标记,定义了cadidate轨迹。我们在1例先天性遗传性上睑下垂(CHP)患者中发现了缺失突变。我们还发现,在未患病的父亲和弟弟中存在这种错义突变,DMBX 1基因不太可能是CHP的致病基因,因此我们改变了我们的研究目标,在一个大家族中进行连锁分析,寻找新的CHP位点。我们用ABI Prism Linkage Mapping Set-MD 10对15名成员(包括4名患病个体)进行了检测。使用FASTLINK ver.4.1P中的MLINK软件或Genehunter软件进行LOD评分计算。D1 S2697(1 p)、D1 S255(1 p)、D1 S484(1 q)、D5 S630(5 p)、D 7S 669(7 q)和D14 S276(14 q)等6个标记的LOD值较高,表明可能存在连锁关系。我们在这些标记周围设置另一个STRP标记进行单倍型分析。我们发现1p35.3-36.1和14q21.1- 23.2两个区域是可能的候选位点,但我们不能确定其中一个区域。部分成员可能存在突变单倍型而无CHP表型,提示该家系存在不完全易位。我们将重新评估该家系成员的表型,并对新家系进行连锁分析,以确定CHP的候选位点。
