Lynch syndrome is an inherited disorder caused by a mutation in one of several genes responsible for DNA repair. If one parent has Lynch syndrome, there is a 50% chance that each child will inherit the mutated gene and have Lynch syndrome, and a 50% chance they will not inherit the gene and not have Lynch syndrome. It is important to note that even if a child does not inherit the mutated gene, they still have a slightly increased risk of developing certain types of cancer due to their family history of Lynch syndrome.
