Abstract
Background and Clinical Significance: Aceruloplasminemia (ACP), a member of the neurodegeneration with brain iron accumulation (NBIA) spectrum of disorders, is a rare disorder caused by mutations in the ceruloplasmin (CP) gene. Iron accumulation in various organs, including the brain, liver, eyes, and heart, can lead to a broad clinical spectrum. Here, we report the first case of ACP in Greece. Case Presentation: Our patient was a 53-year-old male who was referred to our movement disorders center for a 6-month history of mild, unspecific, episodic dizziness and postural instability, and attention and memory deficits. Brain MRI revealed significant iron accumulation in multiple brain regions, including the dentate nuclei, cerebellar cortex, basal ganglia, thalamus, brainstem nuclei, and hypothalamus. These findings were particularly evident in susceptibility-weighted images. Fundoscopy revealed a normal retina, optic nerve, and macula. Whole-exome sequencing revealed a novel homozygous frameshift mutation in the CP gene [NM_000096.3:p.Thr3232fs (c.9695delC)]. This mutation has not been previously reported and is predicted to result in premature protein termination, supporting its pathogenic nature. Laboratory tests showed no anemia but revealed significantly elevated serum ferritin and low serum iron. Subsequent testing revealed extremely low serum CP and low serum copper. Despite less involvement of the myocardium, our patient succumbed to cardiac arrest. Conclusions: ACP should be considered in cases with minor neurological signs and symptoms. Brain MRI plays a significant role in early diagnosis. Close cardiac monitoring is also important.
