PRRT2 mutations are common in patients with PKD and are significantly associated with an earlier age at onset, longer duration of attacks, a complicated form of PKD, combined phenotypes of dystonia and chorea. Patients with microdeletion of 16p11.2 may have more severe manifestations. The HKE test could contribute to the diagnosis of PKD.
