Higher-order co-mutation interactions in mitochondrial genomes

Studies of pair-wise co-mutation of mitochondrial genome have already provided ample evidences about roles of genetic interactions in manifestation of phenotype under altered environmental conditions. High-altitude is one such condition which causes mitochondrial genome to undergo natural selection. Here, we provide a method to construct and analyse higher-order interactions, namely, 3-uniform hypergraphs of mitochondrial genes for different altitude populations to decipher the role of co-mutating variable sites beyond pair-wise interactions. While the weights distribution of such gene hyperedges manifested power-law for all the altitudes regions, we identified specific genes for each altitude based on highest gene hyperedge weight. This framework of higher-order interaction hypergraphs provides a promising avenue for future investigation of nuclear genomes in context of phenotypic association and genetic disorders.
