ORMDO3 (Oligoribonuclease, mitochondrial): ORMDO3 is a gene that encodes an enzyme crucial for maintaining cellular homeostasis within the mitochondria. ORMDO3 specifically breaks down short mitochondrial RNA fragments, aiding in the regulation of mitochondrial gene expression and ensuring proper mitochondrial function. Dysregulation of ORMDO3 can result in RNA accumulation, compromised mitochondrial activity, and impacts on overall cellular health, with potential links to mitochondrial-related disorders.
