A similar pattern is found between RBD and DLB, where ALP genes SNCA, GBA, and TMEM175 are shared risk factors in both conditions, however, DLB genes APOE and BIN1 (Chia et al., 2021) are not associated with RBD (Gan‐Or et al., 2017; Krohn et al., 2021). The gene discussed is GBA1; the disease is Lewy body dementia.
