Abstract: 
ribosome is an intracellular ribonucleoprotein particle that serves as the site of protein biosynthesis. Ribosomal dysfunction caused by mutations in genes encoding ribosomal proteins (rPs) and ribosomal biogenesis factors (RBFs) can lead to a spectrum of diseases, collectively known as ribosomopathy. phase separation is a thermodynamic process that produces multiple phases from a homogeneous mixture. The formation of membrane-less organelles and intracellular structures, including ribosomes and nucleoli, cannot occur without the involvement of phase separation. Here, the ribosome structure, biogenesis, and their relationship to ribosomopathy are systematically reviewed. The tissue specificity of ribosomopathy and the role of phase separation in ribosomopathy are particularly discussed, which may offer some clues for understanding the mechanisms of ribosomopathy. Then, some new ideas for the prevention, diagnosis, and treatment of ribosomopathy are provided.
