When both parents carry autism traits, the dual parental autism risk is considered higher, meaning the chance of passing on autism to their child increases. Inherited autism is not determined by one gene but rather by a complex genetic combination that involves both parents. Therefore, the risk can be significantly influenced when both parents contribute traits that affect the likelihood of autism.
How Does Genes Affect Autism Risk?
When both parents have genetic traits linked to autism, their genetic variations raise the chances that their child may inherit these traits, leading to autism. This is because autism is thought to have a polygenic nature, meaning multiple genes from both parents can interact in ways that influence the development of the condition. In these cases, the autism chance is generally higher compared to when only one parent carries traits, though other factors like environmental influences can also play a role.
Understanding the Family Pattern:
Understanding how a family of autism works is a specific key for families considering the risk. It helps in early diagnosis and opens the door for early intervention, ensuring that appropriate support is provided from a young age. Recognising the possibility of dual parental autism risk can lead to more proactive care and understanding.
