Dynamic mutation disease
In genetics, a dynamic mutation is an unstable heritable element where the probability of expression of a mutant phenotype is a function of the number of copies of the mutation. That is, the replication product (progeny) of a dynamic mutation has a different likelihood of mutation than its … See more • Most of these diseases have neurological symptoms. • Anticipation/The Sherman paradox refers to progressively earlier or more severe expression of the disease in more recent generations.

This work describes dynamic mutations giving emphasis on triplet repeats diseases, making the parallel with disease anticipation. Treatment strategies that have been developed during the last years are also discussed.
