Multifactorial Disorders
Captions available
The idea
Multifactorial disorders arise from many genes combined with environmental influences, rather than from one gene or one chromosome.
In practice
Type two diabetes, heart disease and anxiety disorders, each shaped by genes and circumstances.
Where people slip
Autism spectrum disorder and obesity are also classed as multifactorial. Genetic risk raises likelihood without deciding the outcome.
