   Genetic anticipation, or trinucleotide repeat expansion, tend to occur with 
such genetic disorders as Huntington's Disease, Friedrich's ataxiz, and myotonic 
dystrophy.  This tendency causes the early onset of such diseases and causes 
them to be more severe.  Why does this occur? Has there been any research that 
trys to reverse this process? Were they successful?

Thanks
