Autosomal Recessive Disorders – an overview | ScienceDirect Topics

This autosomal recessive disorder of copper metabolism, also known as hepatolenticular degeneration, is an autosomal recessive disorder caused by an ATP7B gene mutation on the long arm of chromosome 13. Copper accumulation occurs in the liver and basal ganglia and can lead, if not treated, to progressively severe dystonia and parkinsonism.

Both males and females are affected; often more females than males are affected

What are the different ways a genetic condition can be inherited?

Some genetic conditions are caused by variants (also known as mutations) in a single gene. These conditions are usually inherited in one of several patterns, depending on the gene involved: Many health conditions are caused by the combined effects of multiple genes (described as polygenic) or by interactions between genes and the environment.
