Outline of Final Research Achievements

Phenomena such as X-chromosome inactivation and imprinting in polyploid genomes have been studied. Gene expression is sometimes observed only from one allele, and have been reported to be associated with disease and shown to be important for phenotypic traits. In this study, I developed an in-silico analysis pipeline for allele-specific genomic dynamics, which is expected to be effective to analyze the gene structures and gene expressions specific to each haplotype, without relying on a single representative reference genome.

Academic Significance and Societal Importance of the Research Achievements

各ハプロタイプ配列を出力するツールは研究開始時点でも存在していたが、これらツールの配列を直接入力可能な既存解析ツールは存在していなかった。この状況の要因としては、各ハプロタイプの構築手法は1分子DNAシークエンサー等の新技術を活用することで近年にようやく実用性を帯びてきた事情が挙げられる。近年はオミクス解析の主流が、単一の代表ゲノム配列に依存したプロトコルから、ハプロタイプ配列の総体を「ゲノム」として扱うものへと移りつつあり、本研究の成果は関連研究の推進の一助になると期待される。
