The CCDC141 gene, also known as Coiled-Coil Domain Containing 141, plays a significant role in important cellular processes, particularly in neuronal development. Here are the requested details about CCDC141:

### 1. Associated Genes

CCDC141 has been associated with several other genes, although specific associations may vary across studies. Some genes related to axon guidance, cell adhesion, and neuronal development may include:

- **L1CAM**: Involved in neural adhesion and migration.
- **ROBO1**: Plays a crucial role in axon guidance and neural development.
- **EPHA4**: Part of the Eph receptor family, implicated in nervous system development.
- **VLDLR**: Involved in cell adhesion and migration, particularly in the developing cortex.

### 2. Aging and Age-Related Diseases

As of the last data up to October 2023, there are limited direct studies linking CCDC141 to aging or age-related diseases specifically. However, since CCDC141 is involved in neurodevelopment and migration processes, it could potentially impact neurodegenerative diseases or conditions related to brain development, such as:

- **Neurodevelopmental Disorders**: Mutations in genes involved in neuronal cell migration and function are often associated with disorders like autism spectrum disorders (ASD) or schizophrenia. 
- **Age-Related Cognitive Decline**: Proper centrosomal functioning is critical for maintaining neuronal health, so dysregulation could hypothetically contribute to age-related cognitive decline.

### 3. Drug or Drug Classes Interacting with CCDC141

Currently, there are no specific drugs explicitly targeting CCDC141 found in the literature or databases. Given the intracellular functions of CCDC141, potential drug interactions could be investigated indirectly through pathways it influences, particularly those involving cell adhesion or migration. However, research might still be ongoing, and specific interactions may become clearer in the future.

### 4. Pathways and Biological Processes

CCDC141 is involved in several key biological processes and pathways:

- **Neuron Projection Development**: Critical for the proper formation and functionality of neuronal processes.
- **Cerebral Cortex Radial Migration**: Migrations of neurons from the ventricular zone to their final positions in the brain during development, crucial for the proper structure and function of the cerebral cortex.
- **Centrosome Function and Localization**: Plays a pivotal role in maintaining centrosome integrity and function, affecting cell division and stability.
- **Cell Adhesion**: May participate in processes where cells interact with their environment, crucial for tissue integrity and neural connectivity.

In summary, CCDC141 is crucial for neuronal development and function, contributing to key processes associated with cell migration and centrosome regulation. Further research is needed to clarify its role in aging and related pathologies, as well as any potential therapeutic implications.
