  1. Told you so (see reference).

    I missed from the discussion a mention of the stochastic nature of gene expression, and specifically of the age at onset, as an explanation of the incomplete "penetrance" of mutations with a late expression. Penetrance is a dirty word that explains nothing, as many carriers die from other causes before expression of the mutation.
