And it is precisely latent geometry that we discuss in this article to show how the geometry of the metric space of the graph representing the network can influence its dynamics. The identification of the optimal latent geometry becomes important not only because it determines the topological properties of the graph, a well-established result, but also because in it it is possible to link the concept of dissimilarity between nodes to the concept of distance and thus of the transmission speed of the interaction between nodes, i.e. the propensity and efficiency of their interaction. To give an example of the usefulness of studying the variety, size and curvature of the metric space of a biological network, here we examine the gene network reconstructed from genes involved in the onset and development of chronic myeloid leukaemia (CML). The correct identification of the latent geometry of the network leads to experimentally confirmed results, and, because of this, it is a trustable mean to unveil important information on the dynamics of the network. In the case study under consideration, we show how from the identification of a hyperbolic latent geometry, it is possible to determine a list of candidate gene drivers of the network dynamics.
