Since about 50% people who stammer have been shown to have genetic markers for stuttering, can genetic engineering offer some hope in near future? Those who do not have any family history (remaining 50%), what do you think could be happening in their cases: some new mutation? or have they just picked it up as a habit? One last question: is it possible to predict stuttering in progeny, where both mother and father stutter? Thank you in advance!
