SCA 1 (Spinocerebellar Ataxia Type -1) Test | Sprint Diagnostics
Patient Preparing : There are no specific instructions for you before taking this test. You do not need to fast or alter your dietary habits.
Spinocerebellar ataxia type 1 (SCA1) is a condition characterized by progressive problems with movement. This disorder is associated with mutations in the ATXN1 gene, which plays a critical role in nerve cell functions in the brain. The SCA1 test is a genetic test designed to identify these mutations, thus helping to diagnose the condition.
This test can be beneficial to individuals experiencing symptoms related to SCA1, or to those who have a family history of SCA1. The condition is hereditary and is passed down in families in an autosomal dominant manner, meaning that an affected person has a 50% chance of passing the disorder to each of their children.

Which doctor should I consult if I have abnormal values?
If your test results indicate that you have SCA1, you should consult a neurologist or a genetic counselor. They can guide you through the next steps, which may include further testing, symptom management, and family planning advice.
What are the factors that can affect the SCA1 test results?
As this is a genetic test, the results are generally not affected by lifestyle factors. However, certain laboratory errors can lead to a false positive or false negative result.
Genetic testing, such as the SCA1 test, provides valuable insights into an individual's health status and potential genetic disorders. However, it's crucial to understand that positive results can have profound implications. Therefore, it's always recommended to discuss the potential outcomes and implications with a genetic counselor or healthcare provider before undergoing the test. Understanding your genetic health can help you and your healthcare provider make more informed decisions about your medical care and overall well-being.
