Wilson's disease (WD) is an autosomal recessive disorder characterized by the functional disruption of the copper-transporting protein adenosine triphosphatase 7B (ATP-ase 7B). The disease is caused by mutations in ATP7B gene. It seems that the type of mutation in ATP7B only to some degree determines phenotypic manifestation of WD. We examined two pairs of monozygotic twins discordant for WD phenotype. The first set of twins were ATP7B compound heterozygotes c.3207C>A (p.H1069Q)/c.1211_1212insA (p.N404Kfs). The index case developed severe liver failure followed by depressive symptoms, dysarthria, and tremor at the age of 36. Her sister remained presymptomatic at diagnosis at the age of 39. The second twins were ATP7B c.3207C.A (p.H1069Q) homozygotes. The index case presented with dysarthria and tremor at the age of 26. Her sister remained clinically presymptomatic at diagnosis at the age of 28. We concluded that the phenotypic characteristics of WD are possibly attributable to epigenetic/environmental factors.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010641	Phenotype	The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.	Phenotypes
D005260	Female		Females
D006527	Hepatolenticular Degeneration	A rare autosomal recessive disease characterized by the deposition of copper in the BRAIN; LIVER; CORNEA; and other organs. It is caused by defects in the ATP7B gene encoding copper-transporting ATPase 2 (EC 3.6.3.4), also known as the Wilson disease protein. The overload of copper inevitably leads to progressive liver and neurological dysfunction such as LIVER CIRRHOSIS; TREMOR; ATAXIA and intellectual deterioration. Hepatic dysfunction may precede neurologic dysfunction by several years.
