The reactions, known as pseudo-allergies, often cause patients to endure itchiness, swelling and rashes as an unwanted part of their treatment plan. The reactions can be so severe they may stop patients from taking their needed medications and sometimes can even prove fatal. 

Two Genetic Mutations May Interact to Lower Heart Attack Risk

February 3, 2015 1:24 pm | by Ohio State Univ. | News | Comments

Researchers have determined that two mutations on a single gene can interact in a way that lowers the carrier's risk for a heart attack.  The variants are found in a gene called DBH, which regulates an enzyme involved in the conversion of dopamine to norepinephrine - both of which are important chemical messengers and hormones.
