STRING identified PTPRC (a gene in the Green module with evidence of colocalisation, Fig. 3A,B) as the protein with the highest number of interactions and, therefore, as a putative master regulator of the identified asthma-associated modules (Fig. 3C; hub protein permutation p-value = 0.01, Supplementary Materials Fig. E10). The gene discussed is PTPRC; the disease is asthma.
