### WDR73 Gene Overview

The **WDR73 (WD Repeat-Containing Protein 73)** gene encodes a protein characterized by the presence of multiple WD40 repeats, which are structural motifs often participating in protein-protein interactions and signaling pathways.

#### 1. Associated Genes
While the NCBI and UniProt summaries do not specify other genes associated with WDR73, studies on Galloway-Mowat syndrome and related pathways highlight the importance of a network of genes involved in cilia function, microtubule organization, and cytoskeletal dynamics. Genes associated with these processes that may have interactions with WDR73 include:
- **WDR19**: Implicated in ciliary function and may have overlapping roles.
- **DYNC1H1**: Involved in dynein function and microtubule dynamics.
- **ARL13B**: Connected to cilia function and could be relevant in the context of WDR73 mutations and their effects.

#### 2. Aging and Age-Related Diseases
Research directly linking WDR73 to aging is limited; however, its role in microtubule organization and cellular division suggests potential involvement in processes directly or indirectly related to aging, such as:
- **Cellular Senescence**: Disruption of cell cycle regulation due to WDR73 mutations could affect cellular aging.
- **Neurodegenerative Diseases**: Given its involvement in the central nervous system, abnormalities or altered expression of WDR73 could contribute to the pathogenesis of age-related neurodegenerative disorders.

#### 3. Drug and Drug Class Interactions
While there are no specific drugs universally recognized to target WDR73 directly, understanding its pathway involvement might link it to the following classes:
- **Microtubule Stabilizers**: Such as taxanes (e.g., paclitaxel) that may indirectly affect the dynamics that WDR73 regulates.
- **Kinase Inhibitors**: Given the role of WDR73 in cell division and signaling, certain kinase inhibitors could influence its activity-related pathways.

#### 4. Pathways and Biological Processes
The WDR73 gene is involved in several key biological pathways, primarily due to its role in microtubule dynamics and cytoskeletal organization:
- **Cell Cycle Regulation**: Involvement in mitotic spindle positioning suggests a role in ensuring proper chromosomal segregation.
- **Microtubule Organization**: As suggested by its expression at spindle poles, it is likely critical in organizing microtubules during cell division.
- **Cilia Assembly and Function**: Although the association is still under investigation, its connection to ciliary and centrosomal functions may implicate WDR73 in processes regulated by the primary cilium.

### Summary
The WDR73 gene plays a significant role in cellular mechanics, particularly in relation to microtubule dynamics and organization. Mutations lead to the development of rare conditions like Galloway-Mowat syndrome and indicate potential consequences on aging and age-related cellular functions. While direct pharmacological interactions may not be established, the gene's pathways may intersect with drug classes involved in cancer and neurodegeneration, reflecting its potential importance in disease contexts related to both cellular division and maintenance.
