The pathophysiology of dystonia in Wilson disease (WD) is complex and poorly understood. Copper accumulation in the basal ganglia, disrupts dopaminergic pathways, contributing to dystonia's development via neurotransmitter imbalance. Despite advances in diagnosis and management, WD with dystonia remains a challenging condition to treat.

Copper (Cu) dysregulation, often stemming from ATP7B gene mutations, exacerbates neurological disorders like Huntington's, Alzheimer's, and Parkinson's diseases. Monoisoamyl 2,3-dimercaptosuccinic acid (MiADMSA) shows promise in mitigating Cu induced neurotoxicity by chelating intracellular Cu ions, reducing oxidative stress, and restoring antioxidant enzyme function. However, challenges such as poor bioavailability hinder its therapeutic efficacy.

An 11-year-old girl with quiescent ulcerative colitis had sustained elevation of liver enzymes. Although she had no clinical symptoms suggestive of Wilson's disease, such as Kayser-Fleischer rings, laboratory data showed decreased serum copper and ceruloplasmin levels and increased urinary copper excretion. Genetic testing showed pathogenic variants in allele 1: c.

Wilson's disease (WD) (OMIM 277900) or hepatolenticular degeneration is an autosomal recessive disorder caused by impaired copper excretion with subsequent accumulation in the liver, brain, and other tissues of the body. The defects in copper metabolism are based on various pathogenic variants of the ATP7B gene encoding copper-transporting P-type ATPase. The aim of this work is to search for pathogenic variants of the ATP7B gene among Eastern Eurasian patient cohorts and to pick correlations between pathogenic variants, gender, age of onset of the disease, and the course of the disease.

Hepatolenticular degeneration, also known as Wilson's disease, is a type of autosomal recessive genetic disorder of copper metabolism. The causative gene, ATP7B, is located on the long arm of chromosome 13 and encodes a P-type ATPase that is involved in copper transport. Pathogenic mutations in the ATP7B gene sequence lead to the diminished or lost function of the ATP7B protein, resulting in pathological copper deposition in organs such as the liver, brain, kidneys, and cornea.
