The KRT18P46 gene appears to be a pseudogene related to the keratin 18 (KRT18) gene, which encodes a type I cytokeratin protein widely expressed in epithelial tissues.

### Overview of KRT18P46:
- **Gene Symbol:** KRT18P46
- **Type:** Pseudogene
- **Associated Gene:** KRT18

### 1. Associated Genes:
KRT18P46 is primarily associated with the keratin family, particularly KRT18. Other keratin genes, especially those of the type I and II keratin families, may share regulatory sequences or expression patterns, although these associations aren't specifically detailed in broad databases like NCBI or UniProt. Related keratin genes in the same family include:
- KRT17
- KRT19
- KRT14
- KRT8

### 2. Aging and Age-related Diseases:
While specific information directly linking KRT18P46 to aging or age-related diseases is limited, keratin genes such as KRT18 are known to play crucial roles in cellular integrity and response to stress. In general, changes in keratin expression patterns can be associated with aging and may contribute to the pathophysiology of various age-related diseases due to their involvement in maintaining epithelial integrity and homeostasis. For example:
- Alterations in keratin expression can be observed in conditions such as chronic obstructive pulmonary disease (COPD) and cancer.
- KRT18 has been implicated in processes associated with epithelial-mesenchymal transition, which is relevant in various aging-related pathologies.

Further research would be beneficial to determine any specific associations of the KRT18P46 pseudogene with aging.

### 3. Drug Interactions:
Pseudogenes like KRT18P46 usually do not have direct drug interactions because they are non-functional sequences and do not encode proteins. However, drugs targeting KRT functions or pathways involving KRT18 (the functional counterpart) may also indirectly impact KRT18P46. Investigational drugs for conditions affected by keratin alterations may include:
- Anticancer agents that impact keratin expression in tumors (though specific drug classes targeting KRT18 are not clearly defined).
- Keratin-targeting therapies in dermatological applications.

### 4. Pathways and Biological Processes:
As a pseudogene, KRT18P46 does not have experimentally confirmed functions or pathways attributed directly to it. However, the related KRT18 gene is involved in biological processes such as:
- Cellular response to stress
- Keratinization
- Epithelial development and maintenance
- Wound healing

Additionally, since KRT18 interacts with cellular integrity, its pathway involvement may extend to cancer biology, apoptosis regulation, and differentiation processes in epithelial cells.

**Summary:** KRT18P46 is a pseudogene related to the keratin family, particularly KRT18, without direct known associations to specific aging-related processes or drug interactions. Its involvement in biological processes primarily pertains to epithelial functions, and further research is needed to elucidate specific pathways or relationships concerning aging and related diseases.
