Genetic Predisposition in Allergic Reactions to Mold

Genetic predisposition to allergic reactions means that some people inherit genes from their parents that make them more likely to develop allergies, including those to mold. This means their immune systems may react strongly to mold spores, mistaking them for harmful substances. Factors such as family history can increase the risk, alongside environmental influences. If someone has a close relative with mold allergies, they may be more susceptible themselves, even if they haven’t been exposed to mold before. This genetic tendency can play a significant role in how the body responds to allergens like mold.
