The RNU1-64P gene is a member of the small nuclear RNA (snRNA) class and is primarily associated with the splicing of pre-mRNA. It is located in the human genome on chromosome 1. 

### Additional Information:

1. **Associated Genes**:
   - The RNU1-64P gene may not have direct associations with other genes in traditional sense, as it is primarily classified as a non-coding RNA product. However, it may be intricately linked to other genes involved in the spliceosome machinery, such as **SNRNP proteins (e.g., SNRNP70, SNRNP200)**. Individual variants or interactions with other non-coding RNAs or small nucleolar RNAs (snoRNAs) could also contribute to regulatory networks but would require in-depth functional studies to establish those associations.

2. **Aging or Age-Related Diseases**: 
   - As RNU1-64P is a non-coding RNA involved in the splicing process, alterations or dysregulation in splicing factors and associated RNAs have been implicated in various age-related conditions. Changes in splicing mechanisms have been associated with neurodegenerative diseases like Alzheimer’s disease and age-related macular degeneration. However, there is limited specific study on RNU1-64P directly regarding its role in aging or specific age-related diseases.

3. **Drug or Drug Classes**:
   - There are no specific drugs known to directly interact with the RNU1-64P gene. However, drugs that target splicing mechanisms or modify RNA metabolism (such as spliceosome modulators) might indirectly affect the function of snRNAs including RNU1-64P.

4. **Pathways and Biological Processes**:
   - **Key Biological Processes**:
     - Involved in RNA splicing via the spliceosome
     - Plays a role in the maturation of mRNA
     - May have implications in the regulation of gene expression through RNA processing
  
   - **Pathways**:
     - RNA transport and processing pathways
     - Splicing of introns from precursor mRNA

### Summary:
The RNU1-64P gene does not have extensive direct literature tying it to age-related diseases or specific drug interactions but is instead characterized by its role in the broader context of RNA splicing and gene regulation. Further research may elucidate more specific functional roles, particularly in context to aging and disease.
