Common VDR SNPs (FokI, BsmI, ApaI, TaqI) have been studied for associations with immune modulation, but findings are inconsistent, population-specific, and not clinically actionable. No major medical society recommends routine VDR genotyping for allergy prediction. Allergy diagnosis relies on IgE antibodies, skin prick tests, and clinical history—not DNA metabolism panels.

A DNA test can indicate risk for celiac disease (HLA-DQ), but that is an autoimmune condition, not a classic allergy.
