The SRSF3P4 gene is classified as a pseudogene related to the SRSF3 (Serine/Arginine-Rich Splicing Factor 3) gene, which is part of the SR protein family. Pseudogenes are segments of DNA that resemble functional genes but are not expressed as proteins or do not have known biological functions. Below is an expanded response considering your requests.

### 1. Associated Genes
As a pseudogene primarily related to SRSF3, SRSF3P4 may share associations with other members of the SR protein family and related splicing factors. Specific genes of interest may include:

- **SRSF3**: The functionally related splicing factor.
- **SRSF2**: Another splicing factor within the same family.
- **SRSF1**: A well-studied gene in mRNA splicing, possibly sharing regulatory networks with SRSF3P4.

However, as SRSF3P4 is classified as a pseudogene, direct associations with these genes may not imply functional roles in the regulatory networks.

### 2. Aging and Age-Related Diseases
Currently, there is no specific information linking SRSF3P4 directly to aging or age-related diseases, primarily due to its status as a pseudogene. However, as it is associated with the SRSF3 gene, which has been implicated in various cellular functions, including splicing regulation, it may have indirect connections to processes affected during aging, such as gene expression regulation and RNA metabolism. More research would be needed to clarify any links.

### 3. Drug Interactions
As a pseudogene, SRSF3P4 does not have known interactions with drugs or drug classes, as it is not believed to encode a functional protein. Drug interactions are typically studied for protein-coding genes rather than pseudogenes, so information about pharmacological relationships is limited.

### 4. Pathways and Biological Processes
While SRSF3P4 itself is not actively involved in pathways due to its pseudogene status, it may be implicated indirectly through the functional SRSF3 and related genes in several biological processes:

- **mRNA Splicing**: SRSF3P4 may be associated with the regulatory roles of SR proteins in pre-mRNA splicing.
- **Gene Expression Regulation**: SR proteins are known to participate in the regulation of gene expression.
- **RNA Metabolism**: Processes including stability, translation, and decay of mRNA may involve SR protein dynamics, indirectly affecting the behavior of genes like SRSF3P4.
