Who is at highest risk for Achondroplasia ?
A person is most likely to be affected by achondroplasia if one or both of his parents are affected by it. In so far as achondroplasia is inherited as an autosomal dominant disorder (if either parent transmits a copy of the gene, then the child will develop the disease), there is 50 % chance that the child will develop achondroplasia if one parent has achondroplasia. The risk of the child developing the diseases rises to 75% if both parents have achondroplasia. </s>
