What this pathway does
The pathway groups low-weight immune markers that may relate to allergy susceptibility, T-cell signaling, or immune tolerance around cow-milk allergy evidence.
Why it matters
It matters because milk allergy and lactose intolerance are different questions. Milk allergy is immune-mediated and needs allergy-context validation; lactose intolerance is about lactase activity and dose-dependent digestion.
What creates pressure on this pathway
- weak candidate-gene evidence at immune-reactivity loci
- allergy-type symptoms that occur quickly after dairy exposure
- clinical history that points to IgE-mediated milk allergy rather than lactose dose response
Validation markers to consider
- cow-milk specific IgE
- skin-prick testing
- allergist-supervised food-challenge context
Where DNA analysis helps
DNA can only provide weak context here. It should never replace allergy history, cow-milk specific IgE, skin-prick testing, or clinician-guided challenge decisions.
Example interpretation
A weak immune-reactivity signal may make cow-milk allergy context worth checking only when immediate symptoms and clinical history point in the same direction.
Suggested validation: cow-milk specific IgE and allergist review when symptoms fit.
What to do next
- separate immediate allergy-type symptoms from dose-related lactose symptoms
- use clinician-guided allergy testing if symptoms suggest true milk allergy
- do not eliminate dairy long-term based on these SNPs alone
