I have been tested twice and it has been determined that I have 2 copies of the gene for FACTOR V, and I am concerned about my family.  If 1 parent has been diagnosed negative, is it even possible for me to have 2 copies of the gene without something being misdiagnosed?  I have 3 children and 8 grandchildren and would like to know if this should be called to their attention?  Information will be appreciated.

Summarized question: Should i be worried about my children if i have two copies of the gene for FACTOR V?
