Gene panels involve sequencing multiple genes simultaneously to detect mutations. The process starts with a sample, usually blood or saliva, which is then analyzed in a laboratory. The genes included in the panel are chosen based on the clinical presentation of the child. For example, if a child is suspected of having a metabolic disorder, the gene panel would include genes known to be involved in metabolism. The results can help pinpoint the exact mutation responsible for the child's symptoms, guiding further [medical management]().
