The IQCA1-AS1 gene, also known as the IQCA1 antisense RNA 1, is classified as a long non-coding RNA (lncRNA). Here’s a detailed overview of its known characteristics and associations:

### Gene Overview:
- **Symbol:** IQCA1-AS1
- **Type:** Long non-coding RNA (lncRNA)
- **Function:** Long non-coding RNAs like IQCA1-AS1 are involved in the regulation of gene expression, chromatin remodeling, and other cellular processes, although specific functions for IQCA1-AS1 may require further research for elucidation.

### Associate Genes:
While specific genes directly associated with IQCA1-AS1 may not be extensively documented, lncRNAs often modulate the expression of neighboring protein-coding genes or are involved in complex regulatory networks that can include:
- **IQCA1:** The sense transcript, which is related to the IQCA1 protein and could be directly influenced by its antisense counterpart IQCA1-AS1.
- Possible interactions with various oncogenes or tumor suppressor genes, given the involvement of many lncRNAs in cancer-related pathways.

### Aging and Age-Related Diseases:
Research focused on IQCA1-AS1 in the context of aging or age-related diseases is sparse. However, non-coding RNAs, including lncRNAs, have been implicated in aging processes and age-related pathologies, such as:
- **Cellular senescence:** lncRNAs can influence pathways associated with cell aging and longevity.
- **Cancer:** Several lncRNAs are known to regulate pathways related to tumorigenesis, which is often associated with aging.

### Drug and Drug Classes:
As of the latest data available up to October 2023, there may not be specific drugs or drug classes that are explicitly linked to IQCA1-AS1. However, it is important to note that interactions may arise indirectly through the modulation of pathways in which IQCA1-AS1 is involved. It is advisable to look for literature updates or current pharmacological databases for potential interactions.

### Pathways and Biological Processes:
IQCA1-AS1 may be involved in several biological processes, such as:
- **Gene Expression Regulation:** As an lncRNA, it may interact with chromatin modifiers and transcription factors.
- **Cellular Signaling Pathways:** Might play a role in pathways common to various cellular activities, possibly including cancer and developmental processes.
- **Epigenetic Regulation:** Long non-coding RNAs are frequently associated with chromatin remodeling and can impact histone modifications.

### Conclusion:
In summary, IQCA1-AS1 is a long non-coding RNA with potential regulatory functions and connections to various genes, particularly the IQCA1 gene. Its role in aging, age-related diseases, and drug interactions remains to be fully established, indicating an area for further research.

For specific pathways, roles in diseases, and the latest evidence regarding drug interactions, continued literature review or database searches in bioinformatics resources will provide updated insights.
