Understanding Your Results

Results indicate the presence or absence of pathogenic variants in the FAM20A gene. Positive results confirm diagnosis of amelogenesis imperfecta type 1G, while negative results may require further testing.
📊

Positive for pathogenic variants

Confirms diagnosis of AI type 1G. Genetic counseling and dental management recommended.

📊

Negative for pathogenic variants

No mutations detected in FAM20A gene. Consider other genetic or environmental causes.

📊

Variant of uncertain significance

Further testing and family studies may be needed for clarification.

⚠️ When to Consult a Doctor:

Consult a dentist or genetic specialist if you experience dental symptoms like enamel defects, sensitivity, or have a family history of amelogenesis imperfecta.
