Many begin as a brand-new (de novo) change at conception with no fault to either parent, while only some are inherited through families. A genetic counsellor can explain what a specific syndrome means for recurrence in your family.","answer_md":"*\"Is it in our genes — and did we pass it on?\" These are two different questions, and the answer brings real reassurance.*\n\n## In short\nGenetic and chromosomal syndromes are **genetic** by definition — they arise from a change in a child's genes or chromosomes. But genetic does **not** automatically mean **hereditary** (inherited from a parent). Many such conditions begin as a brand-new change — called a *de novo* change — that happens at conception, with no fault and nothing either parent could have done differently. Only some are passed down through families.\n\n## Genetic vs hereditary — the simple difference\nThink of it as two separate ideas:\n\n- **Genetic** means the cause lies in the genes or chromosomes. *Every* one of these syndromes is genetic.\n- **Hereditary** means it was *inherited* — carried from a parent to a child. *Some* genetic syndromes are hereditary; many are not.\n\nA few common patterns:\n- **New (de novo) changes** — for example, Down syndrome usually arises from a chromosomal change at conception, not inherited from either parent.\n- **Inherited changes** — some conditions follow family patterns, where a gene change is carried by one or both parents.\n- **Carrier situations** — parents may carry a change without showing it themselves, yet pass it on.\n\nThis is exactly why a **genetic counsellor** is so valuable: they can explain what *your* child's specific syndrome means for your family, and whether it carries any chance of recurrence.\n\n## What matters most for your child\nWhatever the cause, the path forward is the same — understand your child's strengths and needs today, and build support around them. The genetic origin tells us *why*; a developmental profile tells us *what helps now*.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an article or an app. We then translate that understanding into an everyday plan you can follow.
