PRDM16 is linked to the length and the prominence of the nose as well as the width of the alae, SOX9 is thought to be related to the shape of the ala and nose tip, variation in SUPT3H is thought to influence naso-labial angle and shape of the bridge of the nose, while centroid size (squared root of the squared distances of all landmarks of the face from the centroid) and allometry (relationship of size to shape) have been linked to PDE8A and SCHIP17 genes, respectively, (Cole et al., 2016).

In addition, anthropometric masks have been proposed whereby five landmarks are used to crudely orientate the 3D facial shells which are then non-rigidly mapped on to a template which generates about 10,000 quasi landmarks (Claes et al., 2012).
