Cancer Genetics Summary
... Every person has two copies of each gene; if a mutation occurs in one of their VHL genes they have a backup copy to protect them. People with FAP start life with one copy mutated; if the other copy becomes mutated, it may no longer be able to regulate cell growth and this can lead to tumor formation ...
