Let’s talk genetics 🧬
HAE is an autosomal dominant condition. When one parent has HAE, they will pass on either their normal gene or the affected gene to their child. Children of parents with HAE, therefore, have a 50% chance of inheriting the genetic defect.
👆HAE does not skip generations, which means that children will only inherit it if they have a mother or father with the condition.
