YOUR QUESTION. A CLEARER NEXT STEP.
If one child has a genetic syndrome, can my next child have it too?
Whether a future child can have the same genetic or chromosomal syndrome depends entirely on the specific diagnosis and how it arose — many are one-off events with a low recurrence chance, while others are inherited. Genetic counselling gives the precise, personalised answer. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

One child with a genetic condition does not seal the fate of the next — the real answer lives in the specific diagnosis, and it is a question you can answer with clarity, not fear.
In short
It depends entirely on which syndrome your child has and why it occurred — and for many families the chance of it happening again is low. Some chromosomal differences arise as one-off events at conception and carry only a small recurrence chance; others are inherited and follow more predictable patterns. The single most reliable step is genetic counselling, where a specialist reviews your child's exact diagnosis and your family history to give you a precise, personalised answer.
Why the answer varies
Genetic and chromosomal syndromes are not one thing — they happen in different ways, and each carries its own recurrence picture:
- One-off (de novo) chromosomal changes — many conditions, such as most cases of Down syndrome (an extra chromosome 21), happen by chance during egg or sperm formation. The recurrence chance for the next pregnancy is usually small, though it can rise gently with maternal age.
- Inherited (familial) patterns — some conditions are passed down through families in recognisable ways. Here the recurrence chance can be higher, and testing parents helps clarify it.
- Carrier conditions — occasionally a parent carries a balanced rearrangement or a recessive gene change without being affected themselves; knowing this changes the picture for future pregnancies.
Because these mechanisms are so different, a number quoted for one family may be completely wrong for another. Only a geneticist looking at your child's confirmed diagnosis can give you the figure that truly applies to you.
The step that gives you real answers
Ask your paediatrician for a referral to a clinical geneticist or genetic counsellor. They will confirm the exact diagnosis, may recommend testing for parents, and can discuss options such as prenatal or preconception testing if you are planning another child. This turns a frightening unknown into clear, personalised information — and many families leave reassured.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online form. While recurrence questions belong to a genetic counsellor, our role is to help your current child thrive: through a precise developmental profile and early, joyful developmental therapy tailored to their strengths.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Note the exact name of your child's confirmed diagnosis and whether testing showed it was inherited or a one-off change — this is the key information a genetic counsellor needs to give you an accurate recurrence chance.
In everyday life
Before planning another pregnancy, ask your paediatrician for a referral to a clinical geneticist or genetic counsellor — they can give you a number that is specific to your family, rather than a general estimate from the internet.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Does one child with a genetic syndrome mean my next child will definitely have it?
No. For many conditions the recurrence chance is low because the change happened as a one-off event at conception. Other conditions are inherited and carry a higher chance. Only a genetic counsellor reviewing your child's exact diagnosis can tell you which applies to your family.
Who can tell me my actual recurrence chance?
A clinical geneticist or genetic counsellor. Ask your paediatrician for a referral. They confirm the exact diagnosis, may test parents, and discuss preconception or prenatal testing options if you are planning another child.
Can testing help before another pregnancy?
Yes. Depending on the condition, parents may be offered carrier or chromosomal testing, and prenatal or preconception options may be available. A genetic counsellor will explain what is relevant for your specific situation.
