Variants of , which encodes GluN1, are associated with developmental delay, epilepsy, and cortical malformation. Here, we report a case of arthrogryposis multiplex congenita with polymicrogyria and infantile encephalopathy caused by a heterozygous variant, c.1949A>C, p.(Asn650Thr) of , which could result in the disruption of the third transmembrane domain (M3) of GluN1. This case expands our understanding of the known phenotypes of -related neurodevelopmental disorders.
编码GluN1的基因的变体与发育迟缓、癫痫和皮质畸形有关。在此,我们报告一例由杂合变体c.1949A>C,p.(Asn650Thr)的该基因引起的先天性多发性关节挛缩症伴多小脑回和婴儿脑病,该变体可能导致GluN1的第三个跨膜结构域(M3)的破坏。该病例扩展了我们对与该基因相关的神经发育障碍已知表型的理解。
