Does Fetal Alcohol Spectrum Disorder run in families?

When you love a child touched by FASD, it's natural to wonder whether it could happen again — and the honest answer brings real hope.

In short

Fetal Alcohol Spectrum Disorder (FASD) is not an inherited genetic condition — it is caused by a baby being exposed to alcohol during pregnancy, not by a gene passed down through families. That means FASD is entirely preventable: a future pregnancy with no alcohol exposure carries no risk of FASD. What can recur is the situation — if alcohol is used in another pregnancy — so support around alcohol, planning and pregnancy care is where prevention truly lives.

Understanding why it happens

• The cause is prenatal alcohol exposure, not heredity. Alcohol crosses the placenta and can affect a developing baby's brain and body. FASD is therefore an acquired condition of pregnancy, not a condition written into a family's genes.
• It does not pass from a child with FASD to their own children. A person with FASD will not pass FASD to their baby simply by having it — only alcohol use in that pregnancy could cause it.
• Some families do see more than one affected child. This is usually because alcohol was present in more than one pregnancy, or because of shared circumstances — not because of an inherited gene. Individual sensitivity to alcohol can vary, but exposure remains the necessary cause.
• The empowering truth: because the cause is exposure, FASD is one of the most preventable developmental conditions. An alcohol-free pregnancy means no FASD.

When to seek support

If you have a child with FASD and are planning another pregnancy, speak early with your obstetrician or GP — supportive, non-judgemental help with alcohol and pregnancy planning is available and effective. If you are caring for a child already affected, a developmental check helps map their strengths and needs so the right therapies — for learning, attention, communication and daily living — can begin early, when they help most.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app or online form. For a child living with FASD, that begins with a clear developmental profile through our AbilityScore® assessment, supported by occupational therapy for daily-living and self-regulation skills.
