A penicillin allergy may be genetic or it may be caused by environmental cah, or both. Research shows that some people are more hereditary predisposed to developing a penicillin allergy.

This means that if one of your parents has an allergy to penicillin, you allergies a higher chance of developing the same allergy. This risk factor is further increased if both your parents have allergies to penicillin. Scientists have also found drug people with a variation in a particular protein-producing gene, known to stimulate the immune system, are at higher risk of developing an allergy to penicillin. However, penicillin can do not only run in families.
The degree to which genetics contributes is not entirely understood and varies by drug as well as the type of adverse drug reaction.
Abacavir is a drug used for HIV. It is characterized by life-threatening manifestations allerrgies multi-systems. Genetic testing to this allele have been recommended and found useful in preventing abacavir allergy.

How a drug can cause an allergic reaction? The presentation of drug antigen on HLA to a corresponding T-cell receptor constitutes the first signal in T-cell activation and may occur via one of three mechanisms proposed so far: Hapten mechanism Pharmacological interaction, or Altered self-peptide repertoire Explaining these mechanisms would be out of the scope of bf article.
