In humans, cleft chin is a dimple on the chin. Having a cleft chin is a dominant trait, whereas having cheek dimples is a dominant trait. There is a 25% chance that a child will have a cleft chin when the parents are unaffected carriers of the gene.

Like cheek dimples, chin dimples are inheritable and have a varying degree of prominence. For example, while Kirk Douglas has a very conspicuous cleft chin, his son, Michael Douglas has a much less visible cleft chin. The majority of females do not have cleft chins [1].

The groove of the cleft chin is not just skin-deep, but also on the jawbone, as a groove in the vertical midline of symphysis menti and the soft tissue above it. It is probably the result of incomplete fusion between the left and right halves lower jaw during embryologic development.

Experts believe that cleft chins form the same way that cleft lips form. During the embryonic stage, the tissues most likely fail to meet completely, resulting in a separate development and then fusion along the midline. The result of this fusion (in the region of the bony aspect of the lower jaw) is known as the "symphysis menti."
