### 1. Associated Genes

C9orf40 has been linked to other genes, including but not limited to:

- **C9orf72**: Associated with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), often linked with C9orf40 due to their proximity on chromosome 9.
- **C9orf3**: Shares some functional and positional context with C9orf40.
- **GAPDH**: Although primarily known for its metabolic role, there can be functional relationships involving genes in close proximity.

These associations may not imply direct interactions but signify potential relevance in the same pathways or disease contexts.

### 2. Aging and Age-Related Diseases

While specific studies directly linking C9orf40 to aging or age-related diseases are limited, it is in proximity to the C9orf72 gene which has notable connections to neurodegenerative diseases like ALS and FTD—conditions often impacting older adults. Furthermore, given the dynamic regulation of genes in aging, C9orf40 could play roles in cellular processes that implicate aging or age-related pathologies.

Potentially relevant areas of further exploration:
- Investigations into neuroinflammation, cellular survival, and stress response mechanisms which are crucial in aging and related diseases.
- Studies involving expression levels in aged versus non-aged samples.
