Subject: What gene expresses the way in which an individual folds their hands?

Recently, I was told that the manner in which a person crosses their hands is 
genetically determined.  I would like to know if this was relevant information, 
as it will help with some background information regarding a project that I will 
soon be undertaking.  Hopefully, this will help shed some light on the issue, or 
at least reveal some other sources that I could use to try to find a coherent 
answer.
