### GAPDHP15 Gene Overview

**Gene Symbol**: GAPDHP15  
**Function**: GAPDHP15 (Glyceraldehyde-3-phosphate dehydrogenase pseudogene 15) is classified as a pseudogene associated with the family of glyceraldehyde-3-phosphate dehydrogenases. It may lack full functionality, as it is often regarded as a non-coding gene that potentially plays a regulatory role.

### 1. Associated Genes
GAPDHP15 may be associated with several genes due to its proximity or through regulatory networks. While the specific relationships require further research, here are some genes for consideration:
- **GAPDH**: As a closely related gene, GAPDH (Glyceraldehyde-3-phosphate dehydrogenase) is directly involved in glycolysis and cellular metabolic processes.
- **GAPDHS**: This is another gene in the GAPDH family, primarily involved in spermatogenesis.
- **PKM2**: The pyruvate kinase gene is similarly involved in metabolic processes and may have interlinked pathways with GAPDHP15 due to the role of glycolysis.

### 2. Aging and Age-Related Diseases
Research surrounding GAPDHP15’s exact involvement in aging or age-related diseases is limited due to its classification as a pseudogene.
- **Potential Role in Regulation**: Although not directly linked to specific aging processes, pseudogenes such as GAPDHP15 can influence gene expression and regulatory pathways, which can affect aging and the progression of age-related diseases.
- **Metabolic Disorders**: As a member of the GAPDH gene family, its association with metabolic functions could suggest a potential indirect role in diseases such as diabetes, which are often exacerbated with aging.

### 3. Drug or Drug Classes Interaction
Currently, there is no substantial clinical data on specific drugs directly targeting GAPDHP15 due to its pseudogene status. Nevertheless, there might be potential indirect pathways where molecular compounds interacting with related functional genes within the GAPDH family influence its regulatory network.

### 4. Pathways and Biological Processes
GAPDHP15 is speculated to be involved in:
- **Glycolysis**: Though primarily a pseudogene, GAPDHP15's connection to the GAPDH family suggests a potential role in glycolytic pathways, key for energy production.
- **Metabolic Processes**: It may be involved in carbohydrate metabolism regulation, impacting broader metabolic pathways.
- **Gene Regulation**: As a pseudogene, it may interact with RNA molecules and serve as a regulatory element influencing the expression of neighboring genes.

### Summary
GAPDHP15, considered a pseudogene related to the GAPDH family, plays an intriguing, albeit not completely defined, role in metabolic processes and potentially in the modulation of gene expression. Its exact relationships with other genes, pathways, and diseases related to aging require additional research to fully elucidate its role in biology.
