Genetic counselling gives families clear, personalised answers. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*\"Did we cause this?\" — it's one of the first questions a parent asks, and the honest answer is gentler than you might fear.*\n\n## In short\nSome genetic and chromosomal syndromes do run in families, but many do not — a great number happen for the first time in a child, as a brand-new change that no parent passed on and no parent could have prevented. Whether a particular syndrome is inherited depends entirely on *which* one it is and *how* the genetic change arose. The clearest answers come from a clinical genetics assessment, where genetic counselling and testing can explain what it means for your child and your family.\n\n## How genetics actually works here\nGenetic and chromosomal syndromes are an umbrella term covering many different conditions, and they reach a child in different ways:\n\n- **New (de novo) changes** — Many syndromes, including several of the most well-known chromosomal conditions, arise spontaneously when the egg, sperm or early cell divides. Neither parent carries the change. This is no one's fault, and it is not something diet, lifestyle or anything you did caused.\n- **Inherited patterns** — Some conditions are passed down. A change may be carried by one or both parents — sometimes silently, with no signs in the parent themselves — and then expressed in the child.\n- **Carrier status** — In some families, healthy parents each carry a recessive change that only shows when a child inherits both copies. Parents are often surprised to learn they were carriers.\n- **Chance of recurrence** — Whether future children could be affected varies enormously between conditions, from negligible to predictable. Only a clinical genetics review can estimate this for *your* family.\n\nThis is exactly why a label alone never tells the whole story — the *mechanism* matters as much as the name.\n\n## What this means for your family\nIf your child has, or is being assessed for, a genetic or chromosomal syndrome, genetic counselling is the gold standard. A clinical geneticist can arrange the right tests, explain the inheritance pattern, and talk through what it means for siblings and any future pregnancies — clearly, without judgement, and at your pace. Alongside this medical pathway, developmental therapy helps your child build skills and thrive, whatever the genetics show.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app, a checklist or an online form.
