The **SLC25A13** gene encodes a protein that plays a vital role in mitochondrial transport and metabolism. Below is detailed information regarding the gene, including associations, aging-related information, drug interactions, and involvement in biological pathways.

### 1. Associated Genes
SLC25A13 has implications in various metabolic pathways, and while specific association with other genes may not be explicitly documented in the provided summaries, it is important to consider the following:
- **SLC25A22**: Another member of the mitochondrial carrier family that is involved in transport across the mitochondrial membrane.
- **SLC25A5**: Known to be associated with adenine nucleotide transport, functioning alongside SLC25A13 in metabolic processes.
- **SLC1A5 (ASCT2)**: Although not a mitochondrial transporter, it is involved in the transport of amino acids that could indirectly impact the function of SLC25A13.
  
Additionally, genes involved in urea cycle and nitrogen metabolism may be relevant due to the association of SLC25A13 with citrullinemia.

### 2. Aging and Age-Related Diseases
While direct studies linking SLC25A13 with aging or age-related diseases are limited, some relevant information includes:
- **Mitochondrial Dysfunction**: Impaired mitochondrial function is a hallmark of aging and age-related disorders. Since SLC25A13 is involved in mitochondrial transport, its dysfunction can contribute to metabolic dysregulation observed in aging.
- **Citrullinemia and its Implications**: Citrullinemia type II can lead to neurological complications that may have a more pronounced impact as individuals age, suggesting a link with neurodegenerative conditions.
- **Calcium Homeostasis**: Given that SLC25A13 is activated by calcium, alterations in calcium signaling are often observed as a function of aging, implicating potential roles of SLC25A13 in age-related cellular processes.

### 3. Drug Interactions
As of now, specific drug interactions with SLC25A13 may not be well-documented; however:
- Compounds that modulate mitochondrial function or calcium signaling may indirectly affect SLC25A13 activity.
- **Calcium Channel Blockers**: These may influence the calcium-mediated stimulating activity of SLC25A13.
- Agents targeting metabolic pathways related to urea cycle disorders may be of interest, such as L-arginine supplements for managing citrullinemia.

It is important to check with updated clinical databases and literature for any emerging information related to drug interactions.

### 4. Pathways and Biological Processes
SLC25A13 is involved in several important biological processes and pathways:
- **Malate-Aspartate Shuttle**: The protein is key in facilitating the transport of aspartate and glutamate across the inner mitochondrial membrane, thus playing a crucial role in the malate-aspartate shuttle, which is vital for regenerating NADH and transferring reducing equivalents between mitochondria and cytoplasm.
- **Amino Acid Metabolism**: Involved in the exchange of amino acids (specifically aspartate, glutamate, and L-cysteinesulfinate) which are essential for several metabolic pathways.
- **Energy Metabolism**: By participating in the aspartate/glutamate antiporter activity, SLC25A13 influences the overall energy metabolism within the cell.

Furthermore, the gene may also participate in pathways related to **neurotransmitter transport** and **cellular response to oxidative stress**, reflecting its critical position in maintaining cellular homeostasis.

### Conclusion
Overall, the SLC25A13 gene is essential for mitochondrial function and metabolic homeostasis. Its mutations have clinical implications, particularly in conditions like citrullinemia type II, but further research may reveal more nuanced roles in aging and potential therapeutic interactions.
