Saito F, et al. – This research was meant to extend an association study from chromosome 1 to the whole genome (genome–wide association study) to find susceptibility loci of mandibular prognathism. The genome–wide association study using microsatellites suggested that 6 loci (1p22.3, 1q32.2, 3q23, 6q23.2, 7q11.22, and 15q22.22) were susceptibility regions of mandibular prognathism.
