Lynch Syndrome is generally an inherited condition. The way I understand it is that we are all born with 2 repair genes. They go behind our DNA strands and get rid of the DNA mismatches. Mike was born with only 1 repair gene.So, when you look at his cells, there were thousands of mutated genes, which can lead to cancer. People born with Lynch Syndrome inherit an increased risk of cancer,but not the disease itself. According to an article in the Genetic Home Reference, the genes involved in the repair of mistakes that occur when DNA is copied are the MLH1,MSH2,MSH6,PMS2.
Some symptoms of Lynch Syndrome are families that have more cases of colon cancer than would typically be expected,cancers diagnosed at young ages,repeated cancers every 10 to 15 years,and Colon Cancer or cancers located around the GI tract.
There is no cure for Lynch Syndrome.The good news is that if you are diagnosed with it, there are preventative things that you can do to minimize your cancer risks.For example, colonoscopies at age 18,and every year that sort of thing.
This is inherited,so the bad news is that you have a 50% chance of inheriting it from a parent that has Lynch Syndrome,and 50% chance of passing it on to your children.
