Role of myosin 1H gene polymorphisms in mandibular retrognathism

These results suggest that the rs3825393 polymorphism of the MYO1H gene is associated with an increased risk for mandibular retrognathism. The relatively small sample size used in the study resulted in modest statistical power. A parallel investigation on another population with larger samples to increase the power could further clarify the role of the MYO1H gene in causing mandibular retrognathism.
