What is Sotos Syndrome?

3. An Autosomal Dominant Condition.

Most cases of Sotos syndrome occur due to spontaneous mutation, but it is still important to understand how the gene is passed down genetically. A person with Sotos syndrome has a 50 percent chance of passing it on to his or her child. Autosomal dominant conditions occur when one parent has a normal gene and a mutated gene on a single pair of chromosomes. If the offspring gets one copy of the mutation, they will have Sotos syndrome. In contrast, an autosomal recessive trait requires both parents to have the mutation and for the offspring to receive a copy from each parent.
