Genetic cause for fatal response to Hepatitis A

Researchers have identified a genetic mutation that caused an 11-year-old girl to suffer a fatal reaction to infection with the Hepatitis A virus (HAV). The study reveals that mutations in the IL18BP gene causes the body’s immune system to attack and kill healthy liver cells, and suggests that targeting this pathway could prevent the deaths of patients suffering rapid liver failure in response to viral infection.
