ABSTRACT

N-methyl D-aspartate receptor subtype 2B (GluN2B), encoded by GRIN2B, is one of the components of the N-methyl D-aspartate receptor protein. Aberrations in GRIN2B have been reported to be responsible for various types of neurodevelopmental disorders. We report a Japanese boy with an ~2 Mb interstitial deletion in 12p13 involving the entire GRIN2B gene, who presented with intellectual disability, motor developmental delay and marked macrocephaly.
