RESUMO
BACKGROUND: Pantothenate kinase-associated neurodegeneration (PKAN), sickle cell anemia, and thalassemia are autosomal recessive disorders that can cause iron deposition in tissues during childhood. PKAN is characterized by accumulation of iron in the basal ganglia causing progressive extrapyramidal manifestations. Thalassemia and sickle cell disease can cause iron overload and deposition in tissues, including central nervous system. PRESENTATION OF CASE: we herein report the first report of comorbidity of PKAN, ß-thalassemia-major, sickle cell and glucose-6-phosphate dehydrogenase deficiency (G6PD) anemias in a 9 years old Saudi female patient who presented with gait disturbance, speech difficulty, and progressive movement disorders of the neck, upper and lower limbs. CONCLUSION: Although extremely rare, ß-thalassemia-major, sickle cell and G6PD anemias can be associated with PKAN. It is unknown whether this association is random or due to an unknown factor that may have caused several mutations.
