Among the proteins associated with risk of haematological cancers, we identified associations with risk of multiple blood cancers for members of the FC-receptor protein [FCRL1, FCRL2, FCRL3, FCRL5, FCRLB] and TNF receptor families [TNFRSF4, TNFRSF9, TNFRSF13B, TNFRSF13C, TNFSF13B, TNFSF13]. The gene discussed is TNFRSF13B; the disease is hematopoietic and lymphoid system neoplasm.
