Abstract

Classical linkage programs analyze the segregation of two markers in informative families. When several markers are available for one human chromosome, pairwise analysis can exclude linkage between each marker and an inherited disease. The identification of restriction fragment length polymorphisms has made many new informative markers, assigned to chromosomes, available. We have adapted the multipoint linkage program MLINK developed by Lathrop et al. in order to exclude linkage between cystic fibrosis and several markers known to be on human chromosome 4. The exclusion obtained is greater than that for a pairwise analysis.

摘要

经典的连锁分析程序分析信息丰富的家系中两个标记的分离情况。当一条人类染色体上有多个标记可用时,成对分析可以排除每个标记与一种遗传病之间的连锁关系。限制片段长度多态性的鉴定使得许多新的信息丰富的标记被定位到染色体上。我们采用了Lathrop等人开发的多点连锁分析程序MLINK,以排除囊性纤维化与已知位于人类4号染色体上的几个标记之间的连锁关系。得到的排除结果比成对分析的结果更显著。
