ELOVL6 and metabolic disease: Previous studies have exhibited that the ELOVL6 was closely related to metabolic diseases and energy balance in mammal and fish (Takashi et al., 2012; Motoko et al., 2015; Tan et al., 2015; Zhao et al., 2017; Chen et al., 2018; Nakamura et al., 2018; Su et al., 2018), while few studies were reported in crustaceans.
