FASD and genetic or chromosomal syndromes can both affect a young child's development, learning and growth, but they have different causes. FASD is caused by alcohol exposure before birth and is preventable, with no genetic change involved. Genetic and chromosomal syndromes such as Down syndrome or Fragile X come from differences in a child's genes or chromosomes, present from conception and not caused by anything a parent did. Genetic conditions can often be confirmed by genetic or chromosomal testing; FASD is diagnosed through a clinical picture combining prenatal alcohol exposure, growth, facial signs and learning patterns. Both respond well to early, structured support.

*Both can shape how a child grows and learns — but one begins with something in the womb, and the other is written in the genes from the very start.*

## In short
**Fetal Alcohol Spectrum Disorder (FASD)** happens when a baby is exposed to alcohol before birth — it is *preventable*, and there is no genetic change involved. **Genetic or chromosomal syndromes** (such as Down syndrome or Fragile X) are caused by differences in a child's genes or chromosomes, present from conception and not related to anything a parent did during pregnancy. Both can affect development, learning, growth and behaviour — and both deserve early, gentle support — but they have very different causes, and that shapes how doctors confirm them.

## How they differ
**Cause.** FASD is linked to alcohol crossing the placenta during pregnancy. Genetic and chromosomal syndromes come from a change in the child's DNA — an extra chromosome, a missing piece, or an altered gene — which is why a blood test (genetic or chromosomal testing) can often confirm them, while FASD cannot be diagnosed by a gene test.

**How they show up.** There is real overlap, which is why a careful clinician is so important. Both groups of children may show developmental delay, learning difficulties, attention or behaviour challenges, and sometimes distinctive facial features. In FASD, doctors look at the *combination* of prenatal alcohol exposure, certain facial signs, growth patterns and brain-based learning differences. In genetic syndromes, the pattern of features, growth and development points towards specific tests for confirmation.

**What it means for families.** Neither label defines your child's future. Both respond to early, structured support across speech, learning, motor skills and behaviour — and children often grow far beyond first expectations with the right help.

## When to seek a check
If your young child is slow to reach milestones — talking, walking, playing, connecting — or shows unusual growth or facial features, a developmental check is the kind first step. The cause matters less at this stage than getting the right support started early.

## The Pinnacle way
This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our team looks at your child's whole picture — development, communication, movement and behaviour — and where a [genetic or chromosomal syndrome](/fetal-alcohol-spectrum-disorder) or prenatal cause is suspected, we guide you to the right medical pathway while beginning support straight away through [occupational therapy](/occupational-therapy) and more.
