View Full Version : Have genetics for nose, lip shape, bone structure and facial fat identified?

Because ancestry alone cannot explain phenotype, as Steppe ancestry might be a chinese looking hun or a blond, nordic scythian.
Have specific genes that explain, for eg, straight nose, sculpted lips and an angular, long face identified?

The study identified genes that are involved in bone and cartilage growth and the development of the face. GLI3, DCHS2 and PAX1 are all genes known to drive cartilage growth -- GLI3 gave the strongest signal for controlling the breadth of nostrils, DCHS2 was found to control nose 'pointiness' and PAX1 also influences nostril breadth. RUNX2 which drives bone growth was seen to control nose bridge width.
