01

If I have the disease what are the chances my children will have it?
 

Sitosterolemia is an inherited autosomal recessive genetic condition. An autosomal recessive disease means that to develop the disease two copies of the abnormal gene must be present. Affected individuals inherit two copies of the mutated or changed ABCG8 or ABCG5 genes, one from each parent. Therefore the parents are "carriers" of Sitosterolemia, meaning that they have one normal functioning copy and one non-functioning copy of the genes. With each pregnancy, carriers of Sitosterolemia have a 1 in 4 or 25% chance of having a child with the disease.
