BECAUSE YOU HAVE HAD ONE CHILD WITH TAY-SACHS,YOU MUST EACH CARRY THE ALLELE.ANY CHILD YOU HAVE HAS A 25% CHANCE OF HAVING THE DISEASE.

A Child that have Tay-Sachs experiences problem with coordination,muscle contraction, must stiffness and weakness.there is also difficulty is speaking, swallowing, wasting(uncontrolled weightloss), hearing loss,seizure, and vision loss.

Since the parents of the child in the question claims they don't have Tay- Sachs and no one in the family has it but they came down with a child having Tay-Sachs and one of the major factors to Tay-Sachs as stated above is heredity,the main point to counsel the couples on is that because they have had one child with Tay-Sachs,they most each carry the allele which is obviously recessive so any child they had have has 25% chance of having the disease.
