The RNU6-864P gene is a member of the U6 small nuclear RNA (snRNA) family, which is primarily involved in the splicing of pre-mRNA in eukaryotic cells. This gene is a small nucleolar RNA that is classified as a non-coding RNA and is encoded by the RNA polymerase II or III. While RNU6-864P is not as well-studied as other more prominent genes, I can provide additional context around its known associations and implications.

### 1. Associated Genes
While specific information regarding associated genes for RNU6-864P is limited, small nuclear RNAs often interact with various proteins and may have functional relationships with other snRNA and proteins involved in RNA processing and splicing. Other snRNAs that may be related to RNU6-864P include:

- **RNU6-1**: A well-known spliceosomal RNA involved in pre-mRNA splicing.
- **RNU2**: Another class of U2 small nuclear RNAs associated with splicing processes.

Given the nature of snRNAs, RNU6-864P might also interact with splicing-related proteins such as those in the spliceosome complex, though specific genes haven't been characterized.

### 2. Aging and Age-related Diseases
Current literature may not specifically describe the role of RNU6-864P in aging or age-related diseases. However, given the importance of RNA splicing in cellular function and gene regulation, alterations in the function of small nuclear RNAs (including RNU6-864P) can play a role in various diseases, including some age-related conditions such as neurodegeneration and cancers. Changes in snRNA levels and splicing fidelity have been implicated in the aging process, but concrete evidence tying RNU6-864P directly to aging or age-related diseases is still lacking as of the latest updates.

### 3. Drug Interactions
As RNU6-864P is a non-coding RNA, there are typically no specific drugs or drug classes that directly interact with it. However, the broader class of drugs that target RNA processing, splicing modifiers, or other nucleic acid-related therapies could indirectly affect its function or expression. Examples might include:

- **Antisense oligonucleotides (ASOs)**: These can modulate gene expression at the RNA level, possibly affecting snRNA dynamics.
- **Splicing modulators**: Certain compounds have been studied for their ability to influence RNA splicing and may impact snRNA pathways broadly.

### 4. Pathways and Biological Processes
RNU6-864P is primarily involved in the following biological processes:

- **mRNA Splicing**: A key role in the spliceosome assembly and function, which is crucial for removing introns from pre-mRNAs.
- **RNA Processing**: Participation in modifications and processing of pre-mRNA, which influences gene expression regulation.
  
This gene plays a vital role in ensuring that splicing occurs accurately, thus maintaining proper gene expression and cellular homeostasis.

Overall, while RNU6-864P is a small nuclear RNA, its specific functions, associated genes, and roles in diseases are still an area of ongoing research and may develop further as more studies are conducted on small nucleolar RNAs and their implications in various biological processes.
