It is an acquired, preventable condition caused by alcohol reaching a baby during pregnancy. Genes influence only how strongly a given baby responds to exposure; they never cause the condition. A diagnosis in one child carries no genetic risk to siblings.","answer_md":"*One of the kindest truths about FASD: it isn't written into your child's genes — and it was never inevitable.*\n\n## In short\nFetal Alcohol Spectrum Disorder (FASD) is **not genetic and not hereditary**. It is caused by alcohol reaching a developing baby during pregnancy — meaning it is an *acquired*, preventable condition, not something passed down through family lines like eye colour or an inherited illness. A child cannot inherit FASD from a parent who has it; it arises only from alcohol exposure before birth. Genes do play a small supporting role in *how* a particular baby responds to that exposure, but they are never the cause.\n\n## So what actually causes it?\nWhen a pregnant mother drinks, alcohol crosses the placenta and reaches the baby, whose tiny body cannot break it down the way an adult can. This can affect how the brain and body develop — influencing learning, attention, memory, movement, emotional regulation and sometimes physical growth. FASD describes the *spectrum* of these effects, which vary widely from child to child.\n\nWhere does genetics come in? Only at the edges. Differences in how a mother and baby metabolise alcohol — partly genetic — may mean two babies exposed to similar amounts are affected differently. This is *susceptibility*, not heredity. The condition itself is never inherited, and there is no FASD gene to pass on.\n\n## What this means for your family\nBecause FASD is acquired rather than inherited, a diagnosis in one child carries **no genetic risk** to siblings or future generations — each pregnancy's outcome depends on that pregnancy alone. And every effect of FASD is best understood as a starting point for support, not a fixed limit. Early, structured developmental help genuinely changes trajectories.\n\n## The Pinnacle way\nA clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form. If you have any concern about your child's development, [a clinician can map where your child stands today](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and shape a practical plan. Learn more about [Fetal Alcohol Spectrum Disorder](/fetal-alcohol-spectrum-disorder) and how [our therapy programmes](/occupational-therapy) build skills step by step.\n\n## Trusted sources\nCDC guidance on fetal alcohol spectrum disorders and their cause; WHO and AAP resources on prenatal alcohol exposure and child development.\n\n**Next step —** Curious where your child stands?
