However, only few genetic susceptibility factors have so far been described as risk factors for the development of MM, namely SNPs in TERC(3q26.2), PSORS1C1(6p21.33), TNFRSF13B(17p11.2), CBX7(22q13.1), DNMT3A (2p23.3), ULK4(3p22.1) and CDCA7L/DNAH11(7p15.3), as well as SNPs in TNFα and LTα [50–52]. Here, TNFRSF13B is linked to Miyoshi myopathy.
