[Tourette syndrome].

Tourette Syndrome is not as rare as many health professionals may think. On the contrary it is very common, especially among the Afrikaans population. It is possibly the most common inherited condition. Tourette Syndrome is a neurological variation characterized by "tics" or mannerisms, which can also be combined with one or all of the following: frontal lobe involvement particularly the limbic system; learning problems; anxiety; obsessive-compulsive behaviour; sexual deviations. Most authorities regard TS as a dominant inherited condition although Comings describes it as semi-dominant--semi-recessive.
