Early infantile epileptic encephalopathy-64 (EIEE 64), also called RHOBTB2-related developmental and epileptic encephalopathy (DEE), is caused by heterozygous pathogenic variants (EIEE 64; MIM#618004) in the Rho-related BTB domain-containing protein 2 ( ) gene. To date, only 13 cases with RHOBTB2-related DEE have been reported. We add to the literature the 14th case of EIEE 64, identified by whole exome sequencing, caused by a heterozygous pathogenic variant in RHOBTB2 (c.1531C > T), p.Arg511Trp. This additional case supports the main features of RHOBTB2-related DEE: infantile-onset seizures, severe intellectual disability, impaired motor functions, postnatal microcephaly, recurrent status epilepticus, and hemiparesis after seizures.
早发性婴儿癫痫性脑病64型(EIEE 64),也称为RHOBTB2相关的发育性和癫痫性脑病(DEE),由含Rho相关BTB结构域蛋白2( )基因中的杂合致病变异(EIEE 64;MIM#618004)引起。迄今为止,仅报道了13例RHOBTB2相关的DEE病例。我们通过全外显子组测序鉴定出第14例EIEE 64病例,并将其补充到文献中,该病例由RHOBTB2基因中的杂合致病变异(c.1531C>T),p.Arg511Trp引起。这一新增病例支持了RHOBTB2相关DEE的主要特征:婴儿期起病的癫痫发作、严重智力残疾、运动功能受损、出生后小头畸形、反复癫痫持续状态以及癫痫发作后的偏瘫。
