### RNU6-91P Gene Overview

**Gene Symbol:** RNU6-91P  
**Type:** Small nuclear RNA gene (snRNA)

RNU6-91P is classified as a pseudogene that is part of the U6 small nuclear RNA gene family, which is involved in the splicing of pre-mRNA, a crucial process in gene expression regulation. It predominantly functions in the nucleus, contributing to the assembly of small nuclear ribonucleoproteins (snRNPs) that are essential for the splicing of mRNA precursors.

#### 1. Associated Genes
RNU6-91P is primarily known for its role in RNA processing and splicing. While specific associations beyond those mentioned in NCBI and UniProt are not typically detailed for pseudogenes like RNU6-91P, other genes in the U6 snRNA family include:
- **RNU6-1**
- **RNU6-2**
- **RNU6-3**  
These genes also play significant roles in spliceosomal functions.

#### 2. Aging and Age-Related Diseases
There is limited direct research focused on RNU6-91P in the context of aging or age-related diseases. However, small nuclear RNAs, like U6, are crucial for mRNA processing, and any disruption to their function could potentially affect gene expression regulation involved in aging processes. General studies suggest that alterations in RNA splicing mechanisms are implicated in age-related diseases and conditions such as:
- **Neurodegenerative diseases** (e.g., Alzheimer's disease)
- **Certain cancers**  
It would require further specific research to establish a direct connection between RNU6-91P and these processes.

#### 3. Drug Interactions
Currently, no specific drugs or drug classes have been documented to interact directly with the RNU6-91P gene. Pseudogenes, in general, tend to not be direct targets for drugs, although their expression levels can be indirectly influenced by therapies that affect splicing processes or RNA metabolism.

#### 4. Pathways and Biological Processes
RNU6-91P is involved in several general biological processes, including:
- **RNA splicing process:** Contributes to the maturation of mRNA precursors by facilitating intron removal.
- **Nuclear processing of mRNA:** Plays a role in the pre-mRNA splicing machinery, crucial for producing functional mRNA.
- **Formation of spliceosomal complexes:** Integral to the assembly and function of spliceosomes.

Given the essential role of snRNA in splicing, RNU6-91P, though a pseudogene, may still be functionally relevant through the modulation of its expression or in the regulation of other related genes within the snRNA family.

### Summary
RNU6-91P is a small nuclear RNA gene associated with RNA splicing and potentially related to mechanisms that could influence aging and age-related diseases, although data specific to this gene is limited. Its interactions with drugs are not well characterized, and its contributions to biological processes revolve primarily around RNA processing and spliceosome function.
