Abstract
Can Having Siblings Increase Stuttering as Compared to Being an Only Child?
Highlights
Stuttering is a speech fluency disorder characterized by involuntary repetitions or prolongation of words, syllables, or sounds, or interruptions in the flow of speech, known as blocks
Our findings will assist parents and sibships to encourage self-confidence and prevent negative beliefs in the form of self-blame, guilt or shame associated with stuttering
Studies on the genetics of stutter revealed that GNPTAB, GNPTG, NAGPA, and AP4E1 are related with the lysosomal targeting pathway [10,11,12,13]
Summary
Stuttering is a speech fluency disorder characterized by involuntary repetitions or prolongation of words, syllables, or sounds, or interruptions in the flow of speech, known as blocks. It generally emerges at the age of 2-4 years, with incidence rates ranging from approximately 5-11.2% [1,2,3]. Studies on the genetics of stutter revealed that GNPTAB, GNPTG, NAGPA, and AP4E1 are related with the lysosomal targeting pathway [10,11,12,13]. Recent studies have shown that most of its etiology is genetic, some parents considered their own caregiving or siblings as the cause of stuttering.
