The inheritance pattern autism follows is complex, often involving a mix of genes passed down from both parents. These inherited traits don’t act in isolation; instead, they combine in subtle ways, contributing to a child’s overall family based risk. While no single gene causes autism, multiple genetic variants can build across generations and increase susceptibility.
This genetic mix often described as polygenic means each parent may pass down mild traits or sensitivities that, when combined in a child, raise the likelihood of autism. This gene combination explains why autism may seem to run more strongly in some families, even if parents themselves are not diagnosed.
What to Look for in Inherited Patterns
Recognising inherited patterns helps in early detection and better supports planning.
Communication difficulties:
Children might struggle with verbal or nonverbal cues. CBT focused on social skills can help improve interactions and confidence.
Narrow interests or routines:
A child may fixate on topics or resist change. Behavioural strategies or medication, depending on severity, can reduce distress and increase adaptability.
The role of heritability in autism highlights the value of knowing your family’s neurodevelopmental background.
