A rare genetic mutation that disrupts the production of histamine may help researchers unravel the mystery that surrounds Tourette syndrome.
The mutation discovered by Yale researchers can cause the kinds of tics and other abnormalities that are the hallmark of the syndrome, according to a study published Wednesday in the journal Neuron.
Thus far the genetic anomaly has been discovered only in nine members of a single family: a father and all eight of his children who have both the mutation and Tourette syndrome.
