Interestingly, we observed a strong enrichment in transcription regulation and transcription factor networks, involving important genetic regulators, such as IGF-1, IGF-2, SP1, c-Myc, AR, and p53. In summary, our approach was efficient to discover the putative PCa associated genes using the reported GWAS SNPs as a start and public annotation data, e.g., known genes and eQTLs. This evidence concerns the gene IGF1 and posterior cortical atrophy.
