The SNORD116-2 gene is a member of the small nucleolar RNA (snoRNA) family, which plays a crucial role in the modification and processing of ribosomal RNA (rRNA). Here are more detailed insights based on your request:

### 1. Associated Genes
While information on directly associated genes can be sparse, some studies suggest that SNORD116 genes, including SNORD116-2, may be functionally linked to:
- **SNRPN (Small Nuclear Ribonucleoprotein N)**: This gene is part of the same genomic region and is implicated in Prader-Willi syndrome, which is associated with SNORD116.
- **UBE3A**: Although primarily linked with Angelman syndrome, its interactions can relate to the genomic region containing SNORD116.
- Other snoRNA genes in the *C17orf85* locus, including SNORD116-1 and others, may also be considered functionally related due to their genomic proximity and shared regulatory features.

### 2. Aging or Age-Related Diseases
SNORD116-2 has been suggested to play a role in neurodevelopmental processes, and its dysregulation has been implicated in disorders common in aging populations, particularly those related to neurodevelopmental aspects. In particular:
- **Prader-Willi Syndrome**: SNORD116-2 is part of a cluster of snoRNAs involved in this genetic disorder, which exhibits features that can affect aging, such as obesity and cognitive decline.
- Generally, snoRNAs have been linked to cellular processes that are crucial in age-related diseases due to their roles in ribosome biogenesis and protein synthesis efficiency, which tend to decline during aging.

### 3. Drug Interactions
As of my knowledge cutoff in October 2023, no specific drugs or drug classes have been directly associated with SNORD116-2. However, research is ongoing regarding the therapeutic targeting of snoRNAs in various conditions associated with cognitive decline and other neurodevelopmental disorders. Drugs targeting the pathways related to ribosome biogenesis may indirectly impact the functionality of snoRNA genes in general.

### 4. Pathways and Biological Processes
SNORD116-2 is likely involved in several biological processes:
- **Ribosome Biogenesis**: As a snoRNA, it contributes to the post-transcriptional modifications of rRNA, essential for the formation of ribosomes.
- **RNA Processing**: It is part of the small nucleolar RNA class that is instrumental in modifying other RNA molecules.
- **Gene Regulation**: It may influence the expression of genes in the commonly associated genomic region and affect protein synthesis indirectly.
  
While specific pathways involving SNORD116-2 may require further empirical elucidation, snoRNAs in general are often implicated in the regulation of various cellular processes.

### Conclusion
SNORD116-2 is a small nucleolar RNA that contributes to essential cellular processes, along with associations with key genes and potential implications in neurodevelopmental disorders. Understanding the full spectrum of its interactions and impacts on aging and age-related diseases remains an area of ongoing research.
