Double-Fold Eyelids gene explained

How are "Double-Fold Eyelids" encoded by the genome?

‍

‍Double-fold eyelid, also known as hooded eyelids, where there is a crease are en vogue in Asian countries; everyone seems to want them. Glues to create double-fold eyelids are becoming part of the standard makeup routine. But for those who prefer a more permanent solution, surgery to create double-fold eyelids is an increasingly popular option, with over 40,000 Japanese women undergoing the procedure each year.

‍

In a genome-wide association study of over 11,000 Japanese women, investigators found some new gene loci associated with double-fold eyelids. Interestingly, the loci were associated with a gene that has been previously found to be important in skeletal and neural development (which are components that are important to facial structure development in the embryo).
