GOSR2 and early-infantile DEE: For instance, the phenotype associated with MYC/ATX‐GOSR2 has been called an epileptic syndrome with myoclonic seizures (progressive myoclonus epilepsy type 6) in articles from the field of epilepsy,106 as opposed to a syndrome with prominent cortical myoclonus in combination with epilepsy (progressive myoclonus ataxia) in articles from the field of movement disorders.107 Particularly in the fields of movement disorders and epilepsy, the phenotype is a decisive factor for further diagnostics, and inaccuracy of descriptions can lead to erroneous genotype‐phenotype relationships.
