### FAM138B Gene Overview

**Gene Symbol**: FAM138B  
**Gene Description**: FAM138B (Family with sequence similarity 138 member B) is classified as a pseudogene located on human chromosome 1. It is part of a larger family of genes characterized by sequence similarities. 

### Additional Information

1. **Associated Genes**:
   - FAM138B has been studied in relation to several other genes and their variants. Notably, it has been associated with:
     - **FAM138A**: Another gene in the FAM138 family, further research may be required to clarify molecular interactions or regulatory relationships.
     - **CENP** family genes: Implicated in centromere function, though specific relationships may vary, given the complexity of genomic landscapes.
     - Various genes implicated in genomic stability and structural integrity, though specific connections to phenotype would require further research.

2. **Aging and Age-Related Diseases**:
   - While specific research directly linking FAM138B to aging or age-related diseases is limited, the broader gene family (FAM138) has been studied in the context of genomic stability. Genomic instability is often associated with aging and age-related diseases such as cancer.
   - Research may also suggest that changes in expression or mutations within this gene could affect cellular senescence or tumorigenesis over time, though definitive clinical correlations remain to be thoroughly established.

3. **Drugs or Drug Classes**:
   - Currently, no specific drugs or drug classes have been directly associated with FAM138B in the literature. This may be attributed to its classification as a pseudogene; however, it would be advisable to explore relevant treatments or gene therapies tied to associated pathways or the effects on nearby genes.

4. **Pathways and Biological Processes**:
   - Though specific pathways directly involving FAM138B are not extensively characterized due to its pseudogene status, it may still play a structural role in the genomic landscape of human chromosome 1.
   - Biological Processes:
     - Implications in genomic stability: Because pseudogenes can sometimes play roles in regulatory networks, FAM138B's influence may inadvertently be involved in cellular stress responses or regulation of its neighboring genes.

### Conclusion 

FAM138B continues to be a subject of interest due to its location and potential indirect effects on genomic stability. Its status as a pseudogene suggests it may have limited direct functional roles but could still influence the broader genetic framework on chromosome 1. Future research will clarify its biological and clinical relevance, especially regarding aging and associated pathologies.
