MIR4301: MIR4301 is a 65 base-pair long non-coding RNA located on chromosome 11 within the DRD2 intronic region. It shares the same set of associated SNPs as the DRD2 gene [PMC3772989]. In a study on sickle cell disease (SCD) cohorts, a gene-based test identified MIR4301 as a suggestive signal of non-coding RNA [PMC3772989]. Additionally, MIR4301 was predicted to bind to the 3' UTR region of the DRD2 transcript [PMC3772989]. The tissue-selective expression ranking and p value ranking in physically close genes led to DRD2 and MIR4301 being identified as significant genes, respectively [PMC6836538]. The study also suggested that MIR4301 may be involved in regulating systolic blood pressure (SBP) in SCD cohorts through its binding to DRD2 [PMC3772989]. MIR4301 was found to be the most significant gene with a p-value of 5.2x10-5 [PMC3772989]. In addition to MIR4301, other miRNA genes located on chromosome 11q include miR-125b-1, let-7a, and miR-100. However, their functions are currently unknown [PMC5492892].
