Whether it’s real or not, it remains an interesting and exciting notion and is one of the few positive associations made with having a cleft chin. Discover what causes a chin cleft, a unique facial trait influenced by genetics, muscular structure, and inheritance patterns. The Genetics of Cleft Chin Inheritance A cleft chin has traditionally been considered a dominant genetic trait, meaning inheriting just one copy of the associated allele is generally sufficient for the trait to appear. Cleft chins are indeed hereditary, with their presence or absence being determined by specific gene variations. For example, a midline cleft (Tessier number 0) may indicate a holoprosencephaly spectrum, genes that affect midline development (for example, MID1), or specific syndromes, such as oro-facial-digital syndrome or Ellis-van Creveld syndrome. What actually causes cleft chin? When scientists first studied chin shapes in families, they observed that it was very rare for two smooth-chinned parents to have a child with a chin dimple. Jamie, the combination of your genetics and other factors makes you unlikely to have a cleft chin. People often think that cleft chins are plainly birth defects and are not attractive at all.
