Objective
Stuttering is a widespread but little understood disease. There has been a recent increase in neuropathophysiological, genetic, and biochemical studies related to the etiopathogenesis. As developmental stuttering continues in adult males, hormonal factors are thought to have an effect. In this study, an evaluation was made for the first time of serum GPER-1 level in patients with a stutter.
Study design
Prospective case control.
Materials and methods
The study included 30 patients with a stutter, aged < 18 years, and 35 age-matched children as the control group. The Stuttering Severity Instrument-3 form was administered to the patients. Evaluations were made of serum GPER-1, TSH, estradiol, prolactin, and progesterone and testosterone levels.
Results
GPER-1 level was determined as 0.51 (0.42–0.67) ng/mL in the patients and as 0.19 (0.13–0.25) ng/mL in the control group, and the difference was statistically significant (p < 0.001). A statistically significant difference was determined between genders with GPER-1 level of 0.56 (0.44–0.68) ng/mL in the male stuttering patient group and 0.44 (0.35–0.49) ng/mL in the female patient group (p = 0.026). Differential diagnosis with ROC analysis for the serum GPER-1 levels was statistically significant [Area under the ROC curve (AUC): 0.998, confidence interval, CI 0.992-1.000, p < 0.001].
Conclusion
The GPER-1 levels of the stuttering patients were found to be higher than those of the control group and GPER-1 levels of male patients were higher than those of females. As GPER-1 has high sensitivity and sensitivity, it could be considered important in the diagnosis and treatment of stuttering.
