Patient P0000056 has a candidate gene of POLG. However, when JSON exporting, two candidate genes are listed, POLG and POLG1. This was discovered because the patient did not show any candidate genes, but the POLG1 appeared in the JSON export. Imported User 5 then added the POLG candidate gene with the same description. Presumably it should be POLG1, but it's unclear how this second candidate gene is hiding.
