Abstract

Dopa-responsive dystonia (DRD) is an autosomal dominant disease with parkinsonian and dystonic symptoms caused by GCH1 gene pathogenic variants affecting dopamine synthesis. The present case report is the first to link DRD with childhood-onset with ALS, suggesting that complex inheritance patterns in the North African population may contribute to multiple disorders.
