家系分析 家系分析是对基因病患者的家属进行调查,了解有无同类的患者,并将其结果绘成家系图进行分析。这对基因病的诊断和判断遗传方式极为重要。 家系分析首先是有助于区别单基因病和多基因病。同时,也有助于区分某些表型相似的基因病以及垌一基因病的不同亚型。有很多种基因病存在着遗传与非遗传两种类型(表型模拟)。例如先天性白内障,可以是遗传的,但也可因怀孕时母体受风疹病毒 Pedigree analysis is the analysis of the families of patients with genetic disease to find out whether there are similar patients, and the results drawn as pedigree analysis. This genetic disease diagnosis and judgment of genetic methods is extremely important. The pedigree analysis first helps to distinguish between single and polygenic diseases. At the same time, it also helps to distinguish between some phenotypically similar genetic diseases and different subtypes of genetic diseases. There are many genetic diseases, there are two types of genetic and non-genetic (phenotypic simulation). For example, congenital cataracts, can be genetic, but also because of maternal rubella virus during pregnancy
