Between 28% and 60% of children with a speech and language deficit have a sibling and/or parent who is also affected. [14] Down syndrome is another example of a genetic causal factor that may result in speech and/or language impairments. Stuttering is a disorder that is hypothesized to have a strong genetic component as well.
A disfluence or nonfluence is a non-pathological hesitance when speaking, the use of fillers (“like” or “uh”), or the repetition of a word or phrase.
