Abstract:
:Mandibular prognathism is a common dentofacial phenotype with a substantial genetic component; however, few susceptibility loci have been mapped. Ethnicity is a risk factor for mandibular prognathism, and a relatively high prevalence is observed in Asian populations. The hypothesis of this study suggested that a specific locus for mandibular prognathism exists in the Han Chinese population. So, the authors studied a Han Chinese pedigree in which mandibular prognathism was inherited (11 affected, 10 unaffected) in an autosomal dominant pattern. A genomewide linkage scan was performed with the Illumina Linkage-12 DNA Analysis Kit. Multipoint parametric and nonparametric linkage analyses were performed with MERLIN 1.01. A susceptibility locus was identified on chromosome 14q24.3-31.2, with a nonparametric linkage score of 11.341 (empirical P = .020) and a logarithm of the odds score of 2.032 (empirical P = .008). Haplotype analysis refined the candidate locus to a 10.62-cM interval (72.42 to 83.14 cM; 74.57 to 84.66 Mb) between rs1468507 and rs7141857. Within this interval, the candidate functional genes are TGFB3 and LTBP2. In conclusion, the authors detected a suggestive linkage for mandibular prognathism in a Han Chinese pedigree, and this finding can be combined with previous studies to further understand the genetic basis of mandibular prognathism.
