Furthermore, the putamen ‘cyan’ module contained several other genes linked to monogenic hyperkinetic movement disorders, including genes associated with inherited forms of chorea (PDE2A, GPR88, HTT, VPS13A, JPH3) and dyskinetic epileptic encephalopathies (GNB1, UNC13A, GRIN1, STX1B, KNCQ2, and CACNA1B), strongly suggesting that similar neuroanatomical and biological substrates underlie different clinical subtypes of monogenic dystonias and other hyperkinetic movement disorders. This evidence concerns the gene PDE2A and choreatic disease.
