### CCDC138 Gene Summary

**Gene Symbol**: CCDC138  
**Location**: Human Chromosome 3 (3q25.1)  
**Function**: The CCDC138 (Coiled-Coil Domain Containing 138) gene encodes a protein that is thought to be involved in various cellular functions based on its structural characteristics.

#### 1. Associated Genes:
While specific interactions or associations with other genes are not comprehensively listed in the provided summaries, genes often found to be associated with coiled-coil domain containing proteins include those involved in cellular structure and signaling pathways. Some examples could be:

- **CCDC39**
- **CCDC40**
- **CCDC157**
- **CCDC88A**

These genes share functions related to cilia structure, cellular movement, or cytoskeletal organization, though specific interactions with CCDC138 would require further experimental validation.

#### 2. Aging and Age-Related Diseases:
At present, there is limited information directly connecting CCDC138 to aging or age-related diseases. However, coiled-coil proteins are generally implicated in the regulation of various cellular pathways, and mutations or dysregulation within these pathways can lead to age-related conditions. More research would be needed to establish a clear link between CCDC138 and specific age-related diseases.

#### 3. Drug Interactions:
As of the latest available data, there are no specific drugs or drug classes that are known to interact directly with the CCDC138 gene or its protein product. Drugs may indirectly affect pathways that involve CCDC138, but this remains to be fully elucidated through current literature.

#### 4. Pathways and Biological Processes:
CCDC138 is involved in:

- **Cilia Assembly and Maintenance**: Given the association of coiled-coil domain proteins with ciliary structure, CCDC138 may play a role in the formation or maintenance of cilia, which are essential for several signaling pathways.
  
- **Cellular Adhesion and Organization**: Coiled-coil proteins often function in structural assembly of cellular components, which could suggest an involvement in maintaining cellular integrity and coordination.

- **Potential Role in Development**: While specific developmental pathways for CCDC138 are not documented within the summary, genes encoding coiled-coil proteins are often implicated in various developmental processes due to their roles in structural assembly.

#### Conclusion:
Overall, CCDC138 is a gene with significant structural attributes indicative of participation in cellular processes, particularly those involving cilia and cellular dynamics. However, further research is crucial for clarifying its associations with other genes, drug interactions, and its role in aging or disease mechanisms.
