<unk>  has an autosomal recessive pattern of inheritance. It is estimated that 1 in 25,000 babies born in the United States will have some form of the<unk> . Most<unk>  are autosomal recessive disorders, meaning that only individuals inheriting the defective gene from both parents are affected. (The exception is<unk>  II, or Hunter syndrome, in which the mother alone passes along the defective gene to a son.) When both people in a couple have the defective gene, each pregnancy carries with it a one in four chance that the child will be affected. The parents and siblings of an affected child may have no sign of the disorder. Unaffected siblings and select relatives of a child with one of the<unk>  may carry the recessive gene and could pass it to their own children.
