Menkes disease is a rare neurodegenerative disorder due to an intracellular defect of a copper transport protein. We describe a 7 months male patient who presented with seizures, hypoactivity and absence of visual contact. The investigation disclosed pilli torti and thrycorrexis nodosa in the hair, low serum levels of both copper and ceruloplasmin, brain magnetic resonance study showed atrophy and white matter hypointensities on T1-weighted images, electroencephalogram reveals moderate background activity disorganization and epileptiform activity, and muscle biopsy with type 2 fiber atrophy. The clinical, laboratorial, genetic, muscle biopsy and neurophysiological findings in Menkes disease are discussed.

Pregnancy complications pose challenges for both pregnant women and obstetricians globally, with the pathogenesis of many remaining poorly understood. Recently coined as a mode of cell death, cuproptosis has been proposed but remains largely unexplored. This process involves copper overload, resulting in the accumulation of fatty acylated proteins and subsequent loss of iron-sulfur cluster proteins.

Menkes disease is an X-linked recessive genetically inherited metabolic disease caused by an ATP7A gene abnormality that gives rise to impaired copper absorption. Copper deficiency causes symptoms such as characteristic abnormalities in the hair and vascular disorders. Brain MRI findings include a high-signal intensity in the temporal lobe white matter on T2-weighted images and delayed myelination.

Copper, one of the most prolific transition metals in the body, is required for normal brain physiological activity and allows various functions to work normally through its range of concentrations. Copper homeostasis is meticulously maintained through a complex network of copper-dependent proteins, including copper transporters (CTR1 and CTR2), the two copper ion transporters the Cu -transporting ATPase 1 (ATP7A) and Cu-transporting beta (ATP7B), and the three copper chaperones ATOX1, CCS, and COX17. Disruptions in copper homeostasis can lead to either the deficiency or accumulation of copper in brain tissue.

Minerals constitute only 5% of the typical human diet but are vital for health and functionality. Copper, a trace element, is absorbed by the human gut at 30-40% from diets typical of industrialized countries. The liver produces metallothioneins, which store copper.
