All normal variation and diseases in humans result from interactions of genetics and environmental factors. By studying familial disorders with strong genetic contributions, it is possible to localize and identify genes that cause human disease. These genes are blueprints for proteins which can be studied to better understand the biology underlying such disorders. Only through such understanding can we hope to better help patients with these diseases.
