How Genetic Factors Influence Infantile Seizures
Genetic Causes of Infantile Epileptic Encephalopathy Genetic factors can make it more likely for babies to have seizures. Knowing about these factors helps us spot problems early and lower the chance of more seizures in families. Let’s look at how genes affect seizures and the difference between inherited and new mutations.
Genetic Risk Factors
Research has found many genetic risks for infantile seizures. These risks come from genes that control how the brain works. Important genes include SCN1A, CDKL5, and STXBP1. Changes in these genes can mess up brain development and lead to seizures.
Changes in GABRA1 and SYNGAP1 genes also make babies more likely to have seizures. This makes genetic tests key for finding babies at risk. Genetic Causes of Infantile Epileptic Encephalopathy
Inherited vs. De Novo Mutations
It’s important to know the difference between inherited and new mutations in infantile seizures. Inherited mutations come from parents and increase the chance of seizures in kids. For example, if a parent has a SCN1A mutation, their child might get it too and have seizures.
New mutations happen on their own, without coming from parents. They can occur early in development or in parents’ cells. A new STXBP1 mutation can cause seizures in a baby, even if parents don’t have it. So, knowing about inherited and new mutations helps us understand a baby’s risk for seizures.
In short, the mix of genetic risks and the type of mutation matters a lot for seizures. Learning more about this helps us give better care and support to families.
