### 2. Aging and Age-Related Diseases

The role of CDR2L in aging or age-related diseases is not well elucidated in current literature. However, changes in gene expression of proteins involved in neuronal signaling pathways, including those within the CDR2 family, may contribute to age-related cognitive decline or neurodegenerative diseases. There is a growing body of research linking various neurological proteins to disorders such as Alzheimer's and other forms of dementia, although direct evidence for CDR2L specifically remains limited. Further studies may provide insights into potential associations.
