Living with Spinocerebellar ataxia type 19/22
A very rare inherited condition starting in adulthood with mild coordination problems, thinking changes and muscle jerks.
Understanding Spinocerebellar ataxia type 19/22
It causes mild poor coordination (ataxia), thinking and planning difficulty, sudden muscle jerks (myoclonus) and tremor while holding a posture. It starts in adulthood.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Mild poor coordination (ataxia)
- Unsteady walk and balance trouble
- Shrinking of the cerebellum
- Trunk instability
- Loss of bladder control
- Changes in reflexes
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include brain and nervous system specialists and genetic specialists.
- 3Consider genetic testing
Changes in KCND3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
- 4Connect with expert centers
National Ataxia Foundation may keep lists of experts for this condition.
