Symptoms of<unk>  can and usually appear in early development and progress with age. Although the specific frequency of the symptoms is not known, the duration is recognized to be for life; assuming no treatment has been undergone. The symptoms are variable to each individual, can range greatly in severity and are dependent on gene expression. More severe symptoms include: * Globodontia – an abnormal condition that can occur in both primary and secondary tooth development, in which the molars and canines are greatly enlarged. It refers to the enlarged bulbous fused malformed posterior teeth with almost no discernible cusps or grooves. The molars are known to have a rounded globe-like shape. Can attribute to pain. * Sensorineural hearing loss (SNHL) – also known as nerve related hearing loss, is a form of hearing loss associated with complications within the inner ear. * Taurodontism – known as a condition in which the body of a tooth is enlarged at the expense of the roots. This results in an enlarged pulp chamber, lack of proper bonding at the cementoenamel junction, and can cause the pulpal floor to be displaced towards the root. Discomfort and pain are usually associated with these characteristics. * Endodontic-Periodontic lesions – oral lesions that can potentially form into abscesses. May cause further soreness and pain. Other possible, less severe, symptoms involve: * Absent premolars – individuals suffering from<unk>  will typically lack the ability to develop premolars due to its genetic related affects. * Ocular coloboma – an existent hole within the eye of the individual. The hole can be present in either the iris, choroid, optic disc, or retina and is acquired during early/prenatal development. Individuals with these symptoms may exhibit sensitivity to light, blurred vision, and/or blind spots; depending on the size of the missing tissue and its location in the eye.
