Is CYP1A2 useful for Allergie?

Whether CYP1A2 is useful for allergies is not clearly supported by current evidence. CYP1A2 is primarily involved in caffeine and drug metabolism. Some observational studies have explored links between CYP1A2 variants and allergic conditions like asthma or hay fever, but findings are inconsistent and effect sizes are small. Most evidence is mechanistic or associative, not from clinical trials. Therefore, a CYP1A2 genetic test is not considered clinically useful for allergy management. Allergies are polygenic and heavily influenced by environment. A consumer DNA test like MyBody-X may provide suggestive information but should not guide diagnosis or treatment. Caveat: Always consult an allergist for proper testing (skin prick, specific IgE) before making health decisions.
