It can be inherited from an affected parent that has two copies of the mutated X gene, or from a mother who carries one copy of the X mutated gene.<\/p>\n<p>This mutated gene sits on the X chromosome, making it more likely to impact males than females. Women who carry only one mutated X gene usually present with no symptoms until the healthy X chromosome begins to deactivate due to age.<\/p>\n<p>Unfortunately, a cure or treatment for choroideremia has yet to be discovered.
