Telecanthus With Associated Abnormalities (TCAA) is a very rare genetic disorder affecting the eyes and other parts of the body. Major symptoms include very widely spaced eyes (hypertelorism), urinary tract anomalies, and abnormalities in the development of the mouth and the lips.



The G Syndrome and the BBB syndrome, both of which were first described by Dr. John M. Opitz, are now believed to be one and the same disorder and identical to TCAA as well. Males and females seem to be almost equally liable to present with this disorder but the effect is usually more severe on males than on females.
