Cleft chins are common among people originating from Europe, the Middle East and South Asia. [21] There is a possible genetic cause for cleft chins, a genetic marker called rs11684042, which is located in chromosome 2. [22] In Persian literature, the chin dimple is considered a factor of beauty and is metaphorically referred to as "the chin pit ...
Treacher Collins syndrome (TCS) is a genetic disorder characterized by deformities of the ears, eyes, cheekbones, and chin. [5] The degree to which a person is affected, however, may vary from mild to severe. [5] Complications may include breathing problems, problems seeing, cleft palate, and hearing loss. [5]
Mendelian traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns are relatively rare in nature, and many of the clearest examples in humans cause disorders.

[9] [10] Genetic causes are linked with most craniofacial syndromes, and CL/P and other orofacial clefts are recognized as heterogeneous disorders, meaning there are multiple recognized causes. [9] [11] Orofacial clefts have great phenotypic diversity, and their associated genetic environments have called for vast research and investigation.
The face appears flat and oval-shaped, with widely spaced eyes, a small chin, and, in some cases, an opening in the roof of the mouth called a cleft palate. The abdomen is enlarged, and excess fluid may build up in the body before birth (a condition called hydrops fetalis ).
