Presentation
When present the intention tremor is mild and the dysarthria is mild to moderately severe. The ataxia has been described to be either non-progressive or slowly progressive. [ncbi.nlm.nih.gov]

Because this disorder is X-linked, affected females will present later in life (usually around 10 years later) than males. This phenomenon is partly due to the protection, in females, from iron overload due to blood loss during menstruation. [themedicalbiochemistrypage.org]
The iron-loaded erythroblasts, which are present in bone marrow, are called ring sideroblasts. These abnormal cells give the condition its name. [ghr.nlm.nih.gov]
