The **SNORA65** gene, also known as **Small Nucleolar RNA 65**, is classified as a non-coding RNA gene, primarily functioning in the modification of other RNA molecules. Here is a detailed overview of your queries related to the SNORA65 gene:

### 1. Associated Genes:
Although SNORA65 is primarily recognized for its role as a small nucleolar RNA (snoRNA), specific details regarding associations with other genes are often complex and may not be deeply curated in all databases. However, snoRNAs generally function in the modification of rRNA (ribosomal RNA), and thus there could be indirect associations with genes involved in ribosome biogenesis and RNA processing. Some of these genes include:
- **GAR1**: This gene encodes a protein that is involved in the assembly of snoRNPs (small nucleolar ribonucleoproteins), which include snoRNAs.
- **NOL1**: Another gene involved in ribosome biogenesis.

Additionally, there may be functional associations with genes involved in nucleolar dynamics and ribosomal activity, though specific details may vary based on research context.

### 2. Aging and Age-Related Diseases:
Currently, there is limited specific literature linking SNORA65 directly to aging or age-related diseases. However, snoRNAs are generally thought to play roles in ribosome function and cellular homeostasis, which can be impacted by aging. Alterations in snoRNA expression or function can lead to defects in ribosome assembly and function, which are implicated in various age-associated diseases, including cancer and neurodegenerative diseases. Research on the specific function of SNORA65 in these contexts is still emerging.

### 3. Drug Interactions:
There are currently no specific drugs or drug classes that are widely known to interact directly with SNORA65. However, since snoRNAs like SNORA65 play roles in RNA modification and processing, drugs that target RNA pathways or ribosome biogenesis might indirectly affect its function. It would be advisable to consult more focused pharmacogenomic studies for any emerging drug interactions.

### 4. Pathways and Biological Processes:
SNORA65 is primarily involved in:
- **RNA Modification**: SNORA65 is classified as a box C/D snoRNA that is involved in the 2'-O-ribose methylation of rRNA. This modification is essential for ribosome function and activity.
- **Ribosome Biogenesis**: Through its role in snoRNPs, SNORA65 contributes to the processing and assembly of rRNA and ribosomal subunits.
- **Nucleolar Function**: As a component of the nucleolus, SNORA65 plays a role in organizing the nucleolar structure and facilitating the processing of rRNA precursors.

Further research is needed to comprehensively characterize SNORA65's roles in various biological pathways, especially newer pathways that may be uncovered in ongoing studies surrounding RNA biology.

### Summary
Thus, while SNORA65 is a vital player in the nucleolar and ribosomal contexts, its associations with aging, related diseases, and drug interactions are areas of active research and may evolve with continued investigation.
