ORMDO3 (Oligoribonuclease, mitochondrial): ORMDO3 is a gene that encodes an enzyme essential for maintaining cellular homeostasis within the mitochondria. ORMDO3 specifically degrades short mitochondrial RNA fragments, helping to regulate mitochondrial gene expression and ensuring proper mitochondrial function. Dysregulation of ORMDO3 can lead to RNA accumulation, impaired mitochondrial activity, and effects on overall cellular health, with potential links to mitochondrial-related disorders.
