A family history raises the chance without guaranteeing it, and no parent causes it. Diagnosis is made only by a clinician, never from family history alone.","answer_md":"*If tics run in your family, you may be wondering whether your child has \"inherited\" Tourette Syndrome — the honest answer is: genes matter, but they are not the whole story.*\n\n## In short\nTourette Syndrome is strongly **genetic** — it tends to run in families, and a child with a close relative who has tics or Tourette Syndrome is more likely to have them too. But it is not inherited in a simple, single-gene way like eye colour. Many genes each contribute a small amount, and environmental and developmental factors interact with them. So Tourette Syndrome is **heritable and familial, but not predictable** — having a family history raises the chance, it does not guarantee it.\n\n## What the science tells us\nStudies of twins and families show that the tendency toward tics is largely passed down — identical twins share Tourette Syndrome far more often than non-identical twins. Researchers describe it as **polygenic**: dozens of small genetic influences add up, rather than one faulty gene being responsible. This is also why the same family can show a wide range — one relative may have brief childhood tics, another mild lifelong tics, and another fuller Tourette Syndrome. Boys are affected more often than girls. Importantly, **no parent causes Tourette Syndrome through anything they did**, and there is nothing a family did wrong; it reflects how a child's nervous system is wired as it develops.\n\n## What this means for your family\n- A family history is useful information for your clinician, not a sentence — most children with tics do well.\n- Tics often begin between ages 5 and 7, peak in early adolescence, and frequently ease into adulthood.\n- Tourette Syndrome commonly travels alongside ADHD, anxiety or obsessive features, so a whole-child view matters more than the genetics alone.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from a family-history checklist or an online tool. Genetics tell us about chance; a structured, clinician-led assessment tells us about *your* child. We look at how tics, attention, learning and emotional regulation fit together, then build a plan around strengths.
