The **SNORD115-2** gene is part of the small nucleolar RNA (snoRNA) family and is predominantly located in the nucleolus. It belongs to the C/D box snoRNA class, which is involved in the modification of ribosomal RNA (rRNA), particularly through the process of 2'-O-methylation. Here are the details you're interested in regarding SNORD115-2:

### 1. Associated Genes:
While the summaries from NCBI and UniProt may not always mention additional genes explicitly, snoRNAs like SNORD115-2 can be associated with a variety of genes involved in ribosome biogenesis and rRNA processing. One notable gene associated with this family of snoRNAs is **SNORD115** (also referred to as **MBII-52**), which includes multiple snoRNA variants that might share functional roles in rRNA modification. Additionally, there are associations with genes involved in Prader-Willi syndrome due to their chromosomal location.

### 2. Aging and Age-Related Diseases:
SNORD115-2 has been implicated in aspects related to neurological conditions, and its involvement in Prader-Willi syndrome gives insight into its relation to aging or age-related phenotypes. Specifically, neurodevelopmental disorders might have a progression or onset related to aging, although direct evidence linking SNORD115-2 to aging or age-related diseases is still an area of research.

### 3. Drugs and Drug Classes:
Currently, there are no specific drugs or drug classes overtly reported to interact with SNORD115-2. However, given that snoRNAs can have roles in the modification of rRNA and potentially influence ribosome function, any drugs targeting ribosome biogenesis or RNA processing could theoretically affect its expression or functionality. This includes antibiotics that target bacterial ribosomes but may not directly impact eukaryotic snoRNA activity.

### 4. Pathways and Biological Processes:
SNORD115-2 is primarily involved in:
- **Ribosome biogenesis**: It contributes to the maturation of rRNA.
- **RNA processing**: It assists in the post-transcriptional modification of RNA.
- **2'-O-methylation**: As a snoRNA, it guides methyltransferases to specific rRNA nucleotides to carry out methylation, critical for ribosome assembly and function.

### Summary:
SNORD115-2 is a small nucleolar RNA involved in important processes related to rRNA methylation and ribosome synthesis. Its associations with other snoRNAs and implications in Prader-Willi syndrome point to its significance in certain genetic contexts. The exploration of its role in aging and potential drug interactions remains a developing area of research.
