CRYBB2 and breast cancer: To determine whether there is an independent contribution of CRYBB2 and CRYBB2P1 to the promotion of breast cancer and breast cancer disparities, custom scripts were used to search through all available TCGA breast cancer RNA sequencing alignment files (n = 1221) to identify reads that aligned to either CRYβB2 or CRYβB2P1, or both genes.
