### Overview of the SNORD115-26 Gene

**Gene Symbol**: SNORD115-26  
**Description**: SNORD115-26 is a member of the small nucleolar RNA (snoRNA) family, specifically the C/D box snoRNA. SnoRNAs are primarily involved in the modification of other RNAs, particularly ribosomal RNA (rRNA), through methylation and pseudouridylation processes.

### 1. Associated Genes

While specific associations for SNORD115-26 may not be extensively documented, snoRNA genes, including SNORD115-26, are often found in clusters or imprinted regions. Some related genes may include:

- **SNORD115 (also known as U115)**: This consists of a cluster of snoRNA genes, of which SNORD115-26 is one component.
- **other C/D box snoRNAs**: Many snoRNA genes share functional similarities and are part of complex rRNA processing pathways.

### 2. Aging or Age-Related Diseases

While specific studies detailing the association of SNORD115-26 with aging or age-related diseases are limited, snoRNAs in general have been implicated in processes that contribute to cellular aging and disease. For example:

- **Imprinted Gene Expression**: The regulation of imprinted genes can affect lifespan and the development of age-related disorders. Since SNORD115-26 is part of a cluster of imprinted genes, disturbances in its expression could relate to conditions like Williams syndrome and possibly age-related phenotypes.
- **Cancer**: Impaired nucleolar function, often linked to snoRNA dysregulation, is a hallmark of several cancers, which can have aging as a predisposing factor.

### 3. Drug Interactions

Currently, there is no specific information on drugs or drug classes that directly interact with SNORD115-26. However, since it is involved in a complex post-transcriptional modification pathway, any drugs targeting RNA synthesis or modification processes may hypothetically influence its function.

Potentially relevant classes of drugs may include:

- **RNA Modulating Agents**: These could affect the snoRNA landscape indirectly, impacting overall RNA processing and stability.

### 4. Pathways and Biological Processes

SNORD115-26 is involved in several biological pathways and processes, primarily centered around ribonucleoprotein complex assembly and rRNA processing. Key functions may include:

- **Ribosomal RNA Processing**: As a snoRNA, it plays a crucial role in the methylation and pseudouridylation of rRNA.
- **Regulation of Gene Expression**: SnoRNAs like SNORD115-26 can regulate the accessibility of mRNA for translation and the stability of various RNAs.
- **Cell Growth and Proliferation**: By modulating rRNA processing, it impacts cellular functions that are essential for growth and division.

### Summary

In conclusion, SNORD115-26 is an important component of the snoRNA family, influencing rRNA modification and gene expression. Its implications in aging and diseases are areas of ongoing research, and interactions with pharmaceuticals remain broadly defined rather than direct. Further studies may elucidate specific pathways and functional outcomes associated with this snoRNA, contributing to our understanding of its role in health and disease.
