### FDPSP3 Gene Overview

**Gene Symbol:** FDPSP3  
**Full Name:** Farnesyl Diphosphate Synthase Pseudogene 3  

**NCBI Summary:** The FDPSP3 gene is a pseudogene that may have arisen from the duplication of another gene involved in the pathway of farnesyl diphosphate biosynthesis.

### Other Associated Genes
While specific associated genes for FDPSP3 are not commonly listed, genes related to its functional pathways (like those involved in isoprenoid biosynthesis) could be relevant. Some of the key genes involved in isoprenoid biosynthesis include:
- **FDPS** (Farnesyl Diphosphate Synthase): Main gene responsible for the synthesis of farnesyl diphosphate.
- **HMGCR** (3-Hydroxy-3-Methyl-Glutaryl-CoA Reductase): Involved in the cholesterol biosynthesis pathway.
- **IDI1** (Isopentenyl-Diphosphate Delta Isomerase 1): Involved in isoprenoid biosynthesis.

### Aging and Age-Related Diseases
There is currently no direct evidence linking the FDPSP3 gene specifically to aging or age-related diseases since it is classified as a pseudogene. However, due to its association with farnesyl diphosphate synthesis, it may have indirect implications since farnesylation (a post-translational modification) is involved in numerous cellular processes and can affect cellular aging mechanisms. The maintenance of normal lipid metabolism and cell signaling pathways are crucial in aging and can be influenced indirectly by enzymes associated with metabolizing compounds related to the FDPSP3 gene.

### Drug Interactions
At this stage, since FDPSP3 is a pseudogene, it is unlikely to have direct interactions with drugs. However, drugs that affect the main farnesyl diphosphate biosynthesis pathways and other pathways involving FDPS might indirectly involve FDPSP3, including:
- **Statins:** Such as atorvastatin, which inhibit HMGCR and reduce cholesterol levels.
- **Farnesyltransferase inhibitors:** Used in cancer therapies that may indirectly relate to the pathways influenced by FDPS.

### Pathways and Biological Processes
FDPSP3 as a pseudogene does not typically have defined biological functions like coding genes; however, it may be associated with:
- **Isoprenoid biosynthesis pathway**: This includes the synthesis of farnesyl diphosphate, which is integral to producing isoprenoids.
- **Steroid biosynthesis**: Indirectly by affecting precursor synthesis.

### Summary
FDPSP3 is a pseudogene with potential relevance to the farnesyl diphosphate biosynthesis pathway, without direct involvement in typical gene functions tied to aging, drug interactions, or specific biological processes. Its interplay with other genes in farnesylation and isoprenoid biosynthesis might be further studied to uncover its relevance to disease models and aging processes.
