Dr Julian Knight explains how genetic variants modulate gene expression and influence the susceptibility to commom diseases. Genetic variation plays an important role in individual susceptibility to common diseases. Dr Julian Knight's research focuses on how genetic variation between individuals affects the way immune and inflammatory genes are expressed. This helps understand genetic susceptibility to common conditions such as infectious, inflammatory or autoimmune diseases, leading to more targeted and effective treatments for patients. Dr Knight recently published a book titled 'Human Genetic Diversity, functional consequences for health and disease'.
