The SNORA64 gene, known as Small Nucleolar RNA 64, is categorized as a member of the C/D box small nucleolar RNA family, which primarily facilitates the modification of ribosomal RNA (rRNA) and plays crucial roles in ribosome biogenesis. Here is an expanded overview of the gene based on your requests:

### 1. Associated Genes
While specific associated genes may not be explicitly stated in the summaries, SNORA64 may interact with other genes involved in ribosome synthesis and modification, as well as genes related to nucleolar function. Notable associated genes in broader studies of small nucleolar RNAs and related pathways might include:
- **RRP1B** (rRNA processing 1)
- **NOLC1** (nucleolar and coiled-body phosphoprotein 1)
- **NOP58** (nucleolar protein 58 kDa)
These genes are involved in the assembly and processing of rRNA.

### 2. Aging and Age-Related Diseases
Research indicates that disturbances in the expression and function of small nucleolar RNAs, including SNORA64, may be implicated in several age-related diseases. While specific direct associations between SNORA64 and diseases of aging are still under investigation, numerous studies suggest that aberrant nucleolar activity and rRNA modifications can relate to:
- **Cancer**: Dysregulation of nucleolar RNAs has been linked to tumorigenesis and cancer progression.
- **Neurodegenerative Diseases**: Alterations in small nucleolar RNA populations might correlate with age-associated cognitive decline and diseases such as Alzheimer's.
- **Cardiovascular Diseases**: Since the cellular stress and inflammation associated with aging can impact nucleolar function, indirectly influencing the expression of snoRNAs like SNORA64.

### 3. Drug Interactions
Currently, there are no specific drugs or drug classes that directly target SNORA64. However, given its role in RNA modification and potential involvement in cancer, small molecules or therapies that modify general RNA or ribosomal function could have downstream effects that might indirectly influence SNORA64 activity. This includes:
- **Antineoplastic agents**: Some carry the potential to alter nucleolar activity, indirectly affecting the expression and function of snoRNAs.
- **RNA-targeted therapies**: Emerging treatments that modulate non-coding RNAs or RNA processing pathways may impact the function of genes similar to SNORA64.

### 4. Pathways and Biological Processes
SNORA64 is primarily involved in the following pathways and biological processes:
- **Ribosome Biogenesis**: It contributes to the processing and modification of rRNA, integral to ribosome assembly.
- **Nucleolar Function**: Part of the nucleolar machinery that modulates both the stability and processing of rRNAs.
- **RNA methylation and modification**: SNORA64 guides the addition of methyl groups to specific nucleotides in target rRNAs, altering their functional properties.

In summary, the SNORA64 gene plays an essential role in nucleolar function and ribosome biogenesis, with potential implications in aging and various diseases. While direct associations with specific drugs and pathways are limited, ongoing research may unveil more about its broader biological impacts and therapeutic relevance.
