C19ORF12 (Chromosome 19 Open Reading Frame 12): C19ORF12 is a gene located on chromosome 19 that encodes a protein whose function is not fully understood. This protein is believed to play a role in maintaining mitochondrial integrity and metabolism. Its significance is underscored by its association with neurodegeneration accompanied by brain iron accumulation (NBIA), particularly mitochondrial membrane protein-associated neurodegeneration (MPAN). C19ORF12 is thought to support mitochondrial function, potentially through involvement in lipid metabolism or by protecting mitochondrial membranes from oxidative stress. Mutations in this gene have been linked to progressive neurological symptoms, including motor dysfunction, cognitive decline, and iron accumulation in the brain.
