The SNORD73A gene (small nucleolar RNA, C/D box 73A) is classified as a non-coding RNA gene within the broader category of small nucleolar RNAs (snoRNAs). These RNAs play significant roles in the modification of rRNA, mRNA, and other small RNAs, primarily functioning within the nucleolus.

### Key Information about SNORD73A:

1. **Associated Genes:**
   While specific associations are often derived from functional studies, SNORD73A’s precise interactions with other genes are less well-characterized compared to other snoRNP components. However, other snoRNA genes, particularly those involved in rRNA processing and modification, might be indirectly associated with SNORD73A. This includes snoRNA genes like:
   - **SNORD41**
   - **SNORD46**
   - Genes involved in ribosomal biogenesis and modification pathways may also show functional co-regulation or expression correlation with SNORD73A.

2. **Aging and Age-Related Diseases:**
   While direct evidence linking SNORD73A to aging or age-related diseases is limited, the general role of snoRNAs in regulating ribosomal RNA and small RNA biogenesis ties them to cellular aging and proliferation. Dysregulation of snoRNAs has been noted in various cancers, and alterations in nucleolar activity and RNA processing are implicated in age-related degenerative diseases; hence, SNORD73A may indirectly be associated through these mechanisms.

3. **Drug Interactions:**
   Currently, there are no specific drugs or drug classes directly reported to interact with SNORD73A. However, given that snoRNAs can potentially influence gene expression and protein synthesis, any therapies targeting RNA transcription or translation could theoretically vector their effects indirectly through modulating the expression or function of regulatory snoRNAs, including SNORD73A.

4. **Pathways and Biological Processes:**
   - **Ribosome Biogenesis:** As a snoRNA, SNORD73A is involved in the post-transcriptional modification of ribosomal RNA, facilitating proper ribosome assembly.
   - **RNA Modification:** It likely plays a role in guiding the methylation and pseudouridylation processes of rRNA, crucial for the stability and function of the ribosome.
   - **Nucleolar Function:** SNORD73A contributes to various nucleolar activities, which are critical for cellular stress response and regulation of growth cycles.

Overall, while specific information on SNORD73A may be sparse, its contribution to essential cellular processes, particularly in ribosome function and assembly, places it as an important gene within the nucleolar landscape. Its roles in aging and drug interactions still require more detailed exploration to clarify its functional implications in health and disease.
