基于单体型重构的传递不平衡检验

传递不平衡检验是基于家系检测疾病位点与标记位点之间连锁与连锁不平衡的经典分析方法。论文针对紧密连锁位点,提出了单体型的传递不平衡检验方法,并把此方法用于分析IgA肾病的两紧密连锁位点的基因定位数据。首先在估计核心家系的单体型频率的基础上,重构单体型的传递/未传递的交叉分类表格,然后通过检验此表格的对称性与边缘齐性进行传递不平衡检验,同时,自编Excel宏命令VBA程序,用于家系数据单体型频率估计与重构。此方法充分利用所有家系信息,并能处理缺失数据。C2093T-C2081T的单体型多态性与IgA肾病关联。此方法推广了已有单体型传递不平衡检验。

Linkage graph analysis: A linkage-group-based QTL synthesis analysis approach

Consensus quantitative trait loci (QTL) in meta-analysis of multiple independent QTL mapping experiments provides a strong foundation for marker-assisted selection and gene cloning. However, meta-analysis suffers from the lack of available genomic information and the results vary when different reference linkage maps are used. Here, to overcome these limitations, we propose a linkage-group-based QTL synthesis analysis approach that we have named linkage graph analysis. First, a graph model is constructed from derived linkage groups. Next, an unsupervised classification approach is used to obtain marker intervals with co-segregating patterns among multiple genomes. Finally, a frequent itemset mining technique is used to identify the markers (or intervals) closely linked to the QTL. The proposed method was validated by one Monte Carlo simulation study and by real data analysis of cotton genomes. Two major advantages of the new method are: (i) A reference linkage group is not required; (ii) the effect of the initial QTL is reduced because false QTLs can be detected and excluded from the dataset. The ability to reliably identify the markers associated with a true QTL is valuable in crop breeding.

Statistical issues and approaches in endophenotype research

The endophenotype concept was initially proposed to enhance the power of genetic studies of complex disorders. It is closely related to the genetic component in a liability-threshold model; a perfect endophenotype should have a correlation of 1 with the genetic component of the liability to disease. In reality, a putative endophenotype is unlikely to be a perfect representation of the genetic component of disease liability. The magnitude of the correlation between a putative endophenotype and the genetic co...
