Among the 6 genes associated with a more than 2-fold increased risk of PCa in the Chinese population, ZM1Z1 and SRD5A2 are related to Androgen-related pathways, TEX15 is a DNA repair gene, IL-4 is involved in inflammatory responses, miR-23a is a microRNA, and GAS5 is related to the AKT/mTOR signaling pathway. This evidence concerns the gene IL4 and posterior cortical atrophy.
