Huntington disease is caused by an autosomal dominant mutation in the huntingtin gene. This means that only one copy of the mutated gene is needed to cause the disease, and if a child inherits the mutated gene from one parent, they have a 50% chance of developing the disease themselves. It is not X-linked or recessive, and although it can affect males and females equally, it is not related to sex chromosomes.
