PANK1 and schizophrenia: Two parents reported that a child now diagnosed with CDD had previously been diagnosed with autism before being diagnosed with CDD (one of these had received the CDD diagnosis in adulthood); one parent reported their child had briefly been diagnosed with Asperger’s syndrome, then PDDNOS, before being diagnosed with CDD; and one parent reported that their child had previously been diagnosed with schizophrenia, and that pantothenate kinase-associated neurodegeneration had been considered likely (then removed as a diagnosis), before as an adult being diagnosed with CDD.
