Pediatrics IV

The parents of a child who is newly diagnosed with Tay-Sachs disease ask the nurse, “If we have more children, could they be affected?” Which information should be included when responding to the parents?

ExplanationTay-Sachs disease is an autosomal, recessive condition. That means that both parents must have the gene and that there is a one-in-four chance with every pregnancy that the child will have the condition. The disease is not X-linked, so it is not seen more frequently in boys. Hemophilia is X-linked.
