Inheritance/Cause of Swyer syndrome

Figure 4.0: How Swyer syndrome transmitted to other (children)

In most cases, Swyer syndrome occur among people with no history of the disorder in their household. Only some people that suffer Swyer syndrome is induced by the gene from the unaffected father who is an individual has the alteration or mutation in some cells either sperm or egg cells but not in others. In rare instances, a father might carry the alteration in each cell, but as well has other genetic mutations that prevent him from being touched by the disorder of Swyer syndrome. In Y-linked heritage, an adjustment can only be given from father to son or either parent

Based on Figure 4.0, the father is the carrier of this syndrome and the mother is not. Then, as they have children, randomly these children will inherit the genes from their father and they will also inherit and suffer this syndrome, just like both of the daughter, but not the sons.
