Gilles De La Tourette Syndrome: Genetic Marker?

Abstract

In An Accompanying Paper (And In Other Reports), Visual Field Defects In Gilles De La Tourette Syndrome (Ts), A Complex Neuropsychiatric Condition Involving Motor, Vocal And Behavioral Anomalies Have Been Described. Tourette Syndrome Is Thought To Be A Dominant Trait Passed Preferentially From Fathers To Sons Over Daughters. In This Paper, Visual Field Studies Of Families Which Include A Proband Who Has A Confirmed Diagnosis Of Ts Are Presented. To Date, All Ts Patients, All Fathers And A Majority Of Mothers Of Probands Show Characteristic Visual Field Alterations. It Will Be Important To Determine Whether These Visual Field Determinations Serve As A Genetic Marker For This Complex Of Traits.
