RPS19 (Ribosomal Protein S19) is a gene that encodes a component protein of the 40S ribosomal subunit. The protein is essential for ribosome biogenesis, protein synthesis, and cellular proliferation. RPS19 is one of the most commonly mutated genes in Diamond-Blackfan anemia (DBA), a pure red cell aplasia that represents the prototype of ribosomopathies—diseases caused by defects in ribosome assembly or function. [@yoshida2001]

The RPS19 gene is located on chromosome 19q13.2 and encodes a 145-amino acid protein that is highly conserved across eukaryotes. Beyond its essential role in ribosome function, RPS19 has been implicated in various cellular processes and diseases, including cancer and neurological disorders. [@kondon2012]
