The RPL12P23 gene is a pseudogene that encodes a member of the ribosomal protein L12 family. Given its designation as a pseudogene, RPL12P23 is non-protein coding and typically lacks a functional role in ribosome assembly and function, which is characteristic of typical ribosomal protein genes.

### Additional Information on RPL12P23

1. **Associated Genes**:
   - Pseudogenes often have close relatives or homologs in their family. Other members of the ribosomal protein L12 gene family include:
     - RPL12
     - RPL12P1
     - RPL12P2
   - These genes are typically involved in protein synthesis and may share regulatory pathways or structural similarities.

2. **Aging and Age-Related Diseases**:
   - While specific research directly correlating RPL12P23 with aging or age-related diseases is limited due to its classification as a pseudogene, ribosomal proteins and their aggregates have been implicated in neurodegenerative diseases like Alzheimer's and Huntington's diseases. Typically, dysregulation of ribosomal protein genes contributes to cell stress and cellular aging.
   
3. **Drug Interactions**:
   - Currently, there are no specific drugs or drug classes reported to directly interact with RPL12P23 due to its status as a pseudogene. However, drugs targeting ribosomal function, such as macrolides (e.g., azithromycin) or aminoglycosides, may indirectly affect the broader family of ribosomal proteins.

4. **Pathways and Biological Processes**:
   - RPL12P23, while a pseudogene, can still be associated with ribosomal biogenesis pathways indirectly through its homologs. Generally, ribosomal proteins are fundamental components involved in:
     - Translation and protein synthesis.
     - Ribosomal assembly and function.
     - Response to cellular stress.
   - Ribosomal proteins are also involved in various pathways including:
     - The mTOR signaling pathway.
     - Pathways related to apoptosis and cell cycle regulation as they help maintain cellular homeostasis.
  
### Summary 
In summary, while RPL12P23 is classified as a pseudogene with limited direct biological function or clinical relevance, its association with other ribosomal proteins suggests potential contributions to cellular mechanisms underlying aging and disease. Further research may be necessary to elucidate specific interactions, especially as we understand more about the roles of non-coding RNAs and pseudogenes in gene regulation and expression in the context of health and disease.
