Representing coding relations. Partial view of a network created with gene name "hla-a" as input and choosing to add node up to a distance of one. The input node HLA-A, in red, represents a gene with multiple splice variants. The node UBIQ_HUMAN, in yellow, represent a protein coded by multiple genes. The output was chosen to include coding relation. Dashed lines with arrows represent coding relations directed from the gene node to protein nodes coded by each of the splice variants. BisoGenet assigns a distance of zero to coding relations. Solid lines represent protein-protein interaction networks.
