Heritability estimates for structures in the five craniofacial domains: The heritability estimates from unadjusted models and models adjusted for age, sex, race, and height are shown for structures and are shown in each of the five domains. Asterisk: nominally significant (P < 0.05); Double asterisks: significant after Bonferonni correction for multiple comparisons within each domain. SNA, sella–nasion–subspinale angle; SNB, sella–nasion–supramentale angle; Saddle, nasion–sella–basion angle; ACB, anterior cranial base; C3, the third cervical vertebrae; UFH, upper facial height; AFH, anterior facial height (UFH + LFH); PNS, posterior nasal spine; nasopharyngeal area, area within the region defined by the nasion, the anterior nasal spine, and the basion (Figure 4); oropharyngeal area, area within the region defined by the anterior nasal spine, menton, third cervical vertebrae, and the basion (Figure 4); naso-oropharyngeal area, the sum of the nasopharyngeal and oropharyngeal areas.
