Good for you. You are actually reading. Now lets apply it to real life situations.
Genetic conditions are always present at birth. Therefore, they are not acquired. Genetic conditions can result in symptomology that produces stuttering behaviors. However, those behaviors do not always manifest at birth, as the genetic conditions does not always manifest at birth. Therefore, forms of stuttering that are the result of a genetic disorder can
appear to be acquired, when actually, the genetic abnormality that is responsible has been present from birth. It is just that symptomology did not manifest until some point after birth.
You are confusing symptomology with actual genetic conditions and acquired conditions. Stuttering is a symptom. Even when stuttering has been acquired from traumatic brain injury, as in the case of a stroke, it is a symptom of the neurological disorder, not the disorder in and of itself. In fact, int he case of stuttering associated with traumatic neurological insult, the stuttering is a coping mechanism that compensates for short term/long term memory retrieval impairment.
