The SNORD114-12 gene is part of the Small Nucleolar RNA (snoRNA) family, specifically categorized as a C/D box snoRNA which plays a role in the modification of ribosomal RNA (rRNA) through methylation. Below is the information pertaining to your request:

### 1. Associated Genes:
While the specific associations of SNORD114-12 may not be extensively documented, snoRNAs generally have relationships with various genes involved in ribosome biogenesis and RNA modification processes. Key genes associated with this realm may include:

- **NOP58**: A core component of the C/D box snoRNPs that is involved in the methylation of rRNA.
- **FBL**: A gene that encodes a protein (fibrillarin) crucial for the processing of snoRNAs.
- **RRP1B**: Involved in ribosomal RNA processing, which may be influenced by snoRNAs.

### 2. Aging and Age-Related Diseases:
Research has shown that the expression and function of snoRNAs can be altered in aging and age-related diseases such as cancer and neurodegeneration. Specific findings related to SNORD114-12 in the context of aging are not well-documented; however, snoRNAs are implicated in maintaining the integrity of ribosomal function and protein synthesis, both of which can decline with age, potentially leading to:

- **Cancer**: Due to disrupted ribosome biogenesis and protein synthesis.
- **Neurodegenerative diseases**: As altered snoRNA levels may affect neuronal function.

### 3. Drug Interactions:
Currently, there are no specific drugs or drug classes explicitly known to interact with SNORD114-12 identified through conventional pharmacological studies. However, therapeutic strategies targeting ribosomal biogenesis in cancer, such as inhibitors affecting rRNA synthesis or modifying RNA processing pathways, might indirectly influence the activity or function of snoRNA genes, including SNORD114-12.

### 4. Pathways and Biological Processes:
SNORD114-12 is primarily involved in:

- **Ribosome biogenesis**: It is involved in the processing and modification of rRNA, which is crucial for ribosomal assembly.
- **mRNA metabolism**: By influencing the stability and processing of rRNA, snoRNAs contribute to the overall mRNA processing and translation efficiency in the cell.
- **Nuclear RNA processing**: As a component of snoRNPs, it plays a role in the maturation of pre-rRNA into functional rRNA.

Given its role in modifying rRNA, SNORD114-12 contributes to high-fidelity protein synthesis, which is fundamental for cellular function. Further studies are needed to elucidate its broader implications in health, aging, and disease states.
