Additional tests may also be done, including: All children with a GRIN1-related disorder have a pathogenic variant in the gene GRIN1, which encodes the instructions to make a protein in the brain that forms a subunit of the NMDA receptor. Exome sequencing has higher diagnostic yield compared to simulated disease-specific panels in children with suspected monogenic disorders. Female: 81.1 years - Average life expectancy of a US female (at birth). Family training and support is a key element in a successful epilepsy treatment plan. Ages 0-3 years.
