The **SNORD63B** gene encodes a small nucleolar RNA (snoRNA), which is primarily involved in the modification and processing of ribosomal RNA (rRNA). While the specific functions of SNORD63B are not fully elucidated, snoRNAs typically play critical roles in the biogenesis of ribosomes and other RNA molecules.

### 1. Associated Genes:
The SNORD63B gene is part of a larger family of snoRNAs and may be associated with other snoRNAs or genes involved in ribosome synthesis. Some related genes may include:
- Other SNORD family members (e.g., SNORD63, SNORD66).
- Genes involved in rRNA processing, such as **NOP56**, **NOP58**, and **FBL**.

### 2. Aging or Age-Related Diseases:
Current research does not provide direct, extensive evidence linking SNORD63B to aging or specific age-related diseases. However, given its role in rRNA modification and ribosome biogenesis, which is crucial for cellular function, dysregulation of snoRNAs has been implicated in various cancers and may indirectly relate to age-associated molecular changes.

### 3. Drug Interactions:
As of the latest available data, specific drugs or drug classes interacting directly with SNORD63B are not well documented. However, since it is involved in ribosomal function, it may be indirectly impacted by drugs affecting ribosome biogenesis or function, including antibiotics that target protein synthesis.

### 4. Pathways and Biological Processes:
SNORD63B is primarily involved in:
- **rRNA modification**: contributing to the enzymatic processes that add methyl groups or pseudouridylate rRNA.
- **Ribosome biogenesis**: facilitating the maturation of the ribosome by modifying rRNA, which is crucial for protein synthesis.
- **Gene expression regulation**: as snoRNAs can influence the stability and modification of other RNA species involved in gene expression.

In summary, while specific data on SNORD63B might be limited, its classification as a snoRNA implies involvement in essential RNA processing functions that are vital for cellular activities, including those related to aging and disease. Further research would be necessary to elucidate its precise roles and interactions in various biological contexts.
