Scientists from Australia have identified a gene responsible for stuttering in adults. The study, carried out by researchers from the University of Melbourne, included an analysis of 27 members of a four-generation Australian family, of which 13 people suffered from a stutter. According to data, stuttering affects approximately 5% of children and 1% of adults worldwide, reports ufatime.ru.

Four genes were previously known to be associated with the development of stuttering. However, scientists have identified the important involvement of a fifth gene, designated PPID. Damage to this gene affects the movement and function of proteins during brain formation, which in turn changes the structure of neurons and leads to persistent stuttering.
These findings provide new perspectives for further research and development of treatments for stuttering in adults.
