<prompt> Answer this question truthfullyHow is type IIa familial dyslipidemia inherited?  <response>: <reason> Type IIa familial dyslipidemia is inherited in an autosomal dominant pattern, which means that a person only needs to inherit one copy of the mutated gene from either parent to develop the disorder. If a parent has the mutated gene, there is a 50 chance that their offspring will inherit it as well.
