摘要: We report a genome-wide association scan for facial features in ∼6,000 Latin Americans. evaluated 14 traits on an ordinal scale and found significant (P values<5 × 10−8) at single-nucleotide polymorphisms (SNPs) four genomic regions three nose-related traits: columella inclination (4q31), nose bridge breadth (6p21) wing (7p13 20p11). In subsample of ∼3,000 individuals we obtained quantitative related to 9 the phenotypes and, also, measure nasion position. Quantitative analyses confirmed ordinal-based associations, identified SNPs 2q12 associated chin protrusion, replicated reported position with PAX3. Strongest 2q12, 4q31, 6p21 7p13 was observed EDAR, DCHS2, RUNX2 GLI3 genes, respectively. Associated 20p11 extend PAX1. Consistent effect EDAR documented alterations mandible length mice modified Edar funtion.
