Genetics

​

CAH is a recessive inherited disease, meaning one CAH gene must be inherited from each parent to have CAH. 

Genes come in pairs. If a person has two genes that are not associated with CAH, they do not have CAH. If a person has one gene associated with CAH and one gene that is not associated with CAH, they are considered a carrier of CAH. If a person has two genes associated with CAH, they have CAH. 

In the images below, the large flowers represent each parent and the small flowers below represent the probability of CAH outcomes for each of their children. You can hover over each image or click to explore the cases of family genetics and how they can lead to CAH!
