Understanding Your Results
Positive for pathogenic variant
Confirms diagnosis of CA12-related hyperchlorhidrosis. Genetic counseling recommended for management and family screening.
Negative for pathogenic variant
No CA12 mutations detected. Consider other genetic or non-genetic causes of hyperhidrosis.
Variant of uncertain significance (VUS)
Genetic variant found but clinical significance unknown. Further testing or family studies may be needed.
Consult a dermatologist or genetic counselor if experiencing excessive sweating, especially with family history, skin infections, or impact on daily activities.
