The TMEM156 gene encodes a protein that is predicted to be an integral membrane component. Its specific function is not fully characterized, but it is implicated in various cellular processes. Here’s a comprehensive overview of TMEM156:

### 1. Associated Genes
While the summaries do not provide specific associations, genes that are often studied in relation to TMEM156 include those involved in membrane trafficking, cell signaling, and related pathways such as:
- **GRHL2**: A gene involved in epithelial development that may interact with TMEM genes in epithelial tissues.
- **JNK Pathway Genes**: Genes in the c-Jun N-terminal kinase signaling pathway which can be related to TMEM gene function.
- **Other TMEM Family Members**: Other genes in the TMEM family may have overlapping functions or regulatory networks that include TMEM156.
  
Scientific literature may provide additional insights into specific interactions with other genes, especially in the context of phenotype or disease characterization.

### 2. Aging and Age-Related Diseases
As of the most recent data, there is limited direct evidence linking TMEM156 to aging or specific age-related diseases. However, given that membrane proteins often play roles in cellular homeostasis, signaling, and stress responses, TMEM156 may be indirectly involved in processes related to aging, such as:
- **Cellular Senescence**: Membrane proteins can influence senescent cell behavior.
- **Neurodegenerative Diseases**: As many TMEM proteins are implicated in neural function, changes in TMEM156 may have downstream effects on age-related cognitive decline.

Further studies may elucidate a clearer relationship between TMEM156 and aging or age-related conditions, especially considering the gene's predicted membrane association.

### 3. Drug Interactions
As of the latest updates, detailed information about specific drugs or drug classes interacting directly with TMEM156 is scarce. That said, given its predicted integral membrane nature, it could potentially interact with:
- **Membrane-targeting Drugs**: Such as ion channel blockers or specific receptor modulators which could affect similar TMEM proteins and influence their networks.
- **Antineoplastic Agents**: Given the role of membrane proteins in cancer cell signaling, there may be indirect associations with drugs used in oncology.

A comprehensive search through pharmacogenomic databases may yield new drug relationships as research progresses.

### 4. Pathways and Biological Processes
TMEM156 is involved in:
- **Membrane Transport**: Predicted to play a role in the transport and localization of cellular proteins.
- **Intracellular Signaling Pathways**: May participate in signal transduction through its membrane localization, affecting downstream signaling proteins.
- **Cellular Homeostasis**: Contributes to maintaining homeostasis through its function in membrane dynamics and protein trafficking.

Although detailed pathway models connecting TMEM156 directly to specific biological processes are still under investigation, its prediction as an integral membrane protein suggests importance in various signaling and transport pathways.

### Conclusion
While research on TMEM156 is not comprehensive, ongoing studies in genomics and proteomics may uncover additional functional roles, interactions, and clinical significance related to this gene. Consider monitoring databases like NCBI Gene, UniProt, and scientific publications for the latest insights.
