Mutation That Cause Epilepsy
How can you have a SCN1A MUTATION and not have epilepsy or siezures? Is this possible? The person is 27 and it was found with whole exome.
Yes: this is the problem of offering whole exome testing to the public without genetic counseling. The test examines known genes and determines whether a variant from the norm is present. If present in a gene which can cause disease, the following question must be answered: is it disease-producing, a benign variant, or do we know enough about it to say?Call the testing lab for an answer ...Read more
In genetics, a mutation is a change in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element. Mutations result from unrepaired damage to dna or to RNA genomes (typically caused by radiation or chemical mutagens), from errors in the process of replication, or from the insertion or deletion of segments of dna ...Read more
Brain injury: Post-traumatic epilepsy occurs if the brain is injured in a vulnerable area. The amount of force may be variable, as in repetitive head injuries from football or hockey or generic boxing. Many open head injuries can lead to epilepsy.
