The X-linked human glutamate receptor subunit 3 (GRIA3) gene (MIM *305915, Xq25) encodes ionotropic α amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA)-type glutamate receptor subunit 3, which mediates postsynaptic neurotransmission. Variants in this gene can cause a variety of neurological disorders, primarily reported in male patients. Here, we report a female patient with developmental and epileptic encephalopathy who carries the novel de novo GRIA3 variant NM_007325.5: c.1982T > C: p.Met661Thr.
X连锁的人类谷氨酸受体亚基3（GRIA3）基因（MIM *305915，Xq25）编码离子型α-氨基-3-羟基-5-甲基-4-异恶唑丙酸（AMPA）型谷氨酸受体亚基3，该亚基介导突触后神经传递。该基因的变异可导致多种神经疾病，主要在男性患者中报道。在此，我们报告一名患有发育性和癫痫性脑病的女性患者，她携带新的GRIA3基因新生变异NM_007325.5:c.1982T＞C:p.Met661Thr。
