### RNU4-64P Gene Overview
The RNU4-64P gene is a non-coding RNA gene that belongs to the family of U4 snRNA (small nuclear RNA) genes. Small nuclear RNAs are crucial components of the spliceosome, a complex responsible for the removal of introns from pre-mRNA. RNU4-64P may have roles in pre-mRNA splicing and potentially in the regulation of gene expression.

### Associated Genes
While specific associations might not be heavily documented for RNU4-64P in public databases, small nucleolar RNAs (snoRNAs) and splicing-related genes may be indirectly associated due to common functionalities. Pairs of genes in the broader context of snRNA functionality may include:
- **RNU4-1**: As another U4 snRNA, it may share functional similarities.
- **SNRNPs (Small nuclear ribonucleoproteins)** like U4/U6 snRNP, which work with snRNAs like RNU4-64P.

### Aging and Age-Related Diseases
As of the last data available up to October 2023, there is limited direct research connecting the RNU4-64P gene to specific aging processes or age-related diseases. However, given its involvement in splicing and gene expression, potential indirect associations with diseases such as:
- **Cancer**: Aberrant splicing is a known factor in tumorigenesis.
- **Neurodegenerative Diseases**: Disruption in RNA splicing pathways can affect neuronal health.

Further studies may reveal more specific pathways through which RNU4-64P could relate to aging or age-related pathologies.

### Drug Interactions
Currently, there are no known drugs or drug classes that specifically target the RNU4-64P gene. However, considering the role of small nucleolar and nuclear RNAs in gene regulation and splicing, drugs that modulate splicing or RNA processing (such as some anticancer agents) might indirectly affect the gene's function.

### Pathways and Biological Processes
1. **RNA Processing**: RNU4-64P plays a crucial role in mRNA splicing as part of the spliceosome complex.
2. **Small Nuclear RNA Metabolic Process**: The RNA itself is involved in the regulation and maturation of other RNA species in the cell.
3. **Gene Silencing**: Some studies suggest involvement in post-transcriptional regulatory mechanisms, although specific pathways may need further elucidation.
4. **Spliceosome Assembly**: The gene is integral to the assembly of the spliceosomal complex.

In summary, RNU4-64P is a small non-coding RNA with critical roles in RNA processing, particularly in splicing, although limited data exists regarding its association with aging, specific diseases, or therapeutic interventions. Further research could illuminate these relationships and potential drug interactions.
