**TMEM200B Gene Overview**

The TMEM200B gene encodes a protein that is predicted to be an integral membrane component. It belongs to the TMEM200 family, which consists of a group of transmembrane proteins thought to play roles in various cellular functions.

### 1. Associated Genes
The TMEM200B gene may have associations with several other genes, typically through shared pathways or regulatory connections. Some relevant genes that have been studied alongside TMEM200B in various contexts include:

- **TMEM200A**: A closely related member of the TMEM200 family, potentially involved in similar pathways.
- **SLC genes**: Related to solute transport, as many TMEM genes play roles in transport mechanisms.
- **Genes involved in synaptic signaling and neurodevelopment** may also show associations due to the potential role of TMEM proteins in neuronal pathways.

### 2. Aging and Age-Related Diseases
Though specific studies directly linking TMEM200B to aging or age-related diseases may be limited, transmembrane proteins often play roles in cellular senescence, neuronal integrity, and other processes involved in aging. TMEM200B might be implicated indirectly in age-related neurodegenerative diseases, given its potential roles in the nervous system and membrane dynamics.

### 3. Drug Interactions
Currently, there do not appear to be specific drugs or established drug classes that interact directly with TMEM200B in the literature. However, drugs targeting pathways that alter membrane dynamics or neuroprotective agents may indirectly influence the expression or function of TMEM200B.

### 4. Pathways and Biological Processes
TMEM200B is involved in various cellular pathways and biological processes, especially those related to:

- **Membrane Trafficking**: Integral membrane proteins typically play significant roles in the trafficking and localization of proteins, particularly in the context of membrane dynamics.
- **Neuron Development and Function**: Given the association of TMEM family proteins with neuronal activities, TMEM200B may be involved in pathways affecting neuron signaling and synaptic function.
- **Cellular Response to Stress**: Proteins like TMEM200B might play a role in how cells respond to extracellular stressors or changes in the environment.

### Summary
Overall, TMEM200B is a member of the TMEM200 family of proteins, involved in membrane dynamics and potentially linked to neuronal functions and responses to stress. Future research may clarify its roles in aging and specific diseases, as well as any direct interactions pertaining to therapeutics.
