摘要:

我们介绍了一种新的算法称为{ \sc Rec-Gen}重建家谱或\textit{pedigree}的现存人口纯粹从其遗传数据。我们证明我们的方法,给出了一个数学证明的有效性{ \sc Rec-Gen}时,适用于从一个理想化的生成模型,复制一些功能的真实世界的谱系谱系。我们的算法是迭代的,并提供了一个准确的重建的大部分的系谱,同时具有相对较低的\emph{sample complexity},测量的人口的遗传序列的长度。我们提出我们的方法作为原型,进一步调查的谱系重建问题的目标,应用到现实世界的例子。因此,我们的研究结果对日益重要的基因组隐私问题有一些概念上的影响。

英文摘要:

We introduce a new algorithm called {\sc Rec-Gen} for reconstructing the genealogy or \textit{pedigree} of an extant population purely from its genetic data. We justify our approach by giving a mathematical proof of the effectiveness of {\sc Rec-Gen} when applied to pedigrees from an idealized generative model that replicates some of the features of real-world pedigrees. Our algorithm is iterative and provides an accurate reconstruction of a large fraction of the pedigree while having relatively low \emph{sample complexity}, measured in terms of the length of the genetic sequences of the population. We propose our approach as a prototype for further investigation of the pedigree reconstruction problem toward the goal of applications to real-world examples. As such, our results have some conceptual bearing on the increasingly important issue of genomic privacy.
