### SNORD115-13 Gene Overview

**Gene Symbol**: SNORD115-13

**Gene Type**: Small nucleolar RNA gene (snoRNA) 

**Function**: SNORD115-13 is part of the SNORD115 (also known as U115) family of small nucleolar RNAs (snoRNAs), which primarily function in the modification of rRNA. These snoRNAs guide the modification of specific nucleotides in rRNA through base pairing with their target RNA, facilitating the maturation and functional integrity of ribosomal RNA.

### 1. Associated Genes

While specific associations of SNORD115-13 with other genes are not typically documented in conventional comparisons, small nucleolar RNAs often exert regulatory roles on ribosomal biogenesis and may indirectly influence the expression or function of various genes involved in protein synthesis and cellular metabolism. It’s worth noting that the SNORD115 family is located in the parafibromin-encoding gene region on chromosome 1q21.3.

### 2. Aging and Age-Related Diseases

As of now, there are limited direct studies connecting SNORD115-13 specifically to aging or age-related diseases. However, because snoRNAs like SNORD115 are involved in rRNA modification and ribosome biogenesis, their dysregulation may contribute to cellular senescence, alterations in protein synthesis, and possibly aging-related diseases such as cancer or neurodegenerative diseases where protein homeostasis is critical. Any potential links should be further explored through molecular and genetic studies.

### 3. Drug Interactions

Currently, there are no well-established drugs or drug classes explicitly known to interact with the SNORD115-13 gene. However, since snoRNAs can indirectly influence cellular processes that may be targeted by various therapeutic agents, future research could identify relationships between drugs that modulate RNA processes in relation to this gene.

### 4. Pathways and Biological Processes

SNORD115-13 is implicated in several biological processes associated with small nucleolar RNAs, including:

- **Ribosomal RNA processing**: Involvement in the maturation and modification of rRNA during ribosome assembly.
- **Nucleolar organization**: Contributes to the structure and function of the nucleolus, a vital nuclear subdomain for ribosome production.
- **Post-transcriptional modification**: Plays a role in the modification of RNA molecules which is essential for proper cellular function.

These pathways emphasize the gene's role in maintaining ribosome integrity and function, which are crucial for protein synthesis and general cellular health.

### Conclusion

SNORD115-13 represents an important component of the cellular machinery involved in rRNA processing and ribosome biogenesis. While the direct associations with evolutionary processes such as aging and related diseases, therapeutic interactions, and other gene associations may remain largely to be defined, its core role in ribosomal function suggests potential implications for understanding cellular aging and metabolic regulation. Future studies will likely shed more light on the functional significance of SNORD115-13 in various biological contexts.
