We also noted that other genes like MT-CO2, MT2A, and ABCG1 are placed in specific nodes of our molecular networks, thus suggesting that they may play important role/s in ALS, as it has been already reported in other neurodegenerative diseases like AD (Hayashi et al., 2006; Beecham et al., 2014; Lunnon et al., 2017). The gene discussed is MT2A; the disease is amyotrophic lateral sclerosis.
