Understanding Your Results

Results indicate whether pathogenic mutations in the RASA1 gene are detected, which can confirm Parkes Weber syndrome. Positive results require clinical correlation and genetic counseling.
📊

Mutation Detected

Likely diagnosis of Parkes Weber syndrome; consult a geneticist for management.

📊

No Mutation Detected

Reduced likelihood of RASA1-related syndrome; consider other diagnostic tests.

📊

Variant of Uncertain Significance

Further testing or family studies may be needed for clarification.

⚠️ When to Consult a Doctor:

Consult a doctor if symptoms worsen, for family planning advice, or to discuss test results and treatment options.
