Since then, mutations in several other genes have been identified for FTLD with parkinsonism, including chromatin modifying protein 2B, chromosome 9 open reading frame 72 (C9ORF72), fused in sarcoma, valosin-containing protein, and transactive DNA-binding protein (TARDBP) (31, 32). The gene discussed is TARDBP; the disease is Parkinson disease.
