For module #35, while most of the genes locate on 1q34, many of the genes such as UQCRH, PSMB2, PPIH, and YBX1 are involved in RNA processing and have been identified with breast cancer in multiple studies (Miller et al., 2005; Pujana et al., 2007; Barry et al., 2010). Here, YBX1 is linked to breast cancer.
