Ribosomal protein L21 pseudogene 137 (RPL21P137)

RPL21P137 is a *processed pseudogene* related to the ribosomal protein L21 gene[1][3]. Pseudogenes are DNA sequences similar to known genes but lack the capacity to produce functional protein products. RPL21P137 itself has no reported function, role in human disease, or participation in any well-characterized biological pathway. It is not a receptor, enzyme, transporter, transcription factor, or any therapeutic target category[1][3]. RPL21P137 should not be confused with the functional **ribosomal protein L21** (**RPL21**), which is a bona fide component of the 60S ribosomal subunit, involved in protein synthesis, and has clinical relevance in disorders such as hypotrichosis simplex of the scalp[4][5]. RPL21 has aliases including DKFZP686C06101, EL21, FLJ27458, and is located on chromosome 13, but RPL21P137 is a distinct, noncoding pseudogene[2][3]. The entry RPL21P137 is *not a therapeutically actionable target* and does not encode a receptor or other functional protein. It appears to be properly named as a pseudogene and is only relevant as a genomic annotation rather than a protein or drug target. There is no evidence in current databases for molecular classification, biological function, disease role, drug interaction, or biomarker utility for this pseudogene[1][3].
