CTDSP1 and amyotrophic lateral sclerosis: The most downregulated gene was BMPER, an inhibitor of BMP (-10 fold) followed by NIF3LBP1 (-7.4 fold), which binds NIF3 (an amyotrophic lateral sclerosis candidate gene), MCC1 (-7.4 fold) (a tumor suppressor), and PRLR (-4.2) (a prolactin receptor important for decidua function) [42-46].
