With the data analysis using a genome-wide association study (GWAS), we found that IL-32 was closely related to many cancers (Additional file 1: Figure S1), and further analysis showed that IL-32 was closely associated with several genes including ITGAV and TIMP-1 (Additional file 2: Figure S2A and S2B), which have been implicated in skin tumor development. This evidence concerns the gene TIMP1 and skin neoplasm.
