Stutter disease is related to gene mutations

Understanding the causes of stuttering in children has always been a problem for scientists, but recently US scientists have discovered that stuttering is related to genetic mutations.

In a report published in the New England Journal of Medicine, scientists at the National Institute for the Study of Deafness and Diseases (NIDHD) said they initially conducted a one-member study. family in Pakistan.

These Pakistani family members all have congenital stuttering disease. The findings, on the 12th chromosome set of this study, had a mutated gene.

After that, scientists continued to compare the genes of stuttering people in Pakistan, US and British countries with ordinary people.

The results of the discovery of two other genes of people with stuttering have been mutated. Scientists speculate, 9% of stuttering has a relationship with the three mutant genes discovered above. The next step, scientists will continue to find more mutated genes that cause stuttering.

Dennis Reina, a genetic expert, member of the research team, said that 50% to 70% of stuttering is related to gene mutations.

Previously, stuttering had a relationship with factors such as stress, pressure, mental retardation and improper education of parents. However, according to the latest research, the above factors only increase the level of stuttering and are not the main cause of stuttering.
