### FAM90A1 Gene Overview

**Gene Symbol**: FAM90A1  
**Protein Summary**: The FAM90A1 gene belongs to the FAM90 gene family, which is a group of highly conserved genes, though specific functions of many family members remain poorly characterized. 

### 1. Associated Genes

While specific associations might not be extensively documented, genes within the FAM90 family, particularly FAM90A1, could be associated with other genes involved in cell signaling or development, given their general role in cellular processes. Genes such as **FAM90A2** and other family members may have similar functions or regulatory roles. 

**Note**: For precise associations, further studies, especially those analyzing gene co-expression or genetic interaction networks, would be required.

### 2. Aging and Age-related Diseases

Current literature highlights some involvement of FAM90A1 in cellular mechanisms that might be linked to cellular senescence, though explicit mechanisms relating to aging or age-related diseases are not clearly established or prominent. 
Research has suggested the FAM90 family may play roles in regulating cellular processes; however, direct links to aging or specific age-related diseases such as Alzheimer's or other neurodegenerative conditions have not been definitively identified in available studies.

### 3. Drug Interactions

As of the latest updates, there have been no specific drugs or drug classes documented to interact with FAM90A1 directly. Given its membership in the FAM90 family and the general lack of detailed functional information, it is possible that drugs might interact indirectly through pathways influenced by FAM90A1.

### 4. Pathways and Biological Processes

FAM90A1 is likely involved in several biological processes, although specifics may not be well-defined in current literature. Potential involvement could include:

- **Cellular signaling pathways**: Given its family membership, FAM90A1 may be involved in pathways related to cell proliferation and differentiation.
- **Transcriptional regulation**: Some FAM90 family members have been implicated in gene expression control.
- **Response to stress**: Family members may be involved in cellular responses to various stresses, although explicit pathways for FAM90A1 may require more focused studies.

### Conclusion

The FAM90A1 gene is characterized by its membership in the FAM90 family, with limited but emerging insights into its functional roles, particularly in cellular processes. Further investigations are needed to clarify its associations with other genes, its exact roles in aging and disease, interactions with pharmaceuticals, and the biological pathways it affects. Current data emphasize the need for in-depth functional studies to elucidate these aspects comprehensively.
