摘要: 目的 探讨Cohen综合征临床及基因变异特点。方法 回顾分析1例Cohen综合征患儿的临床资料及分子 遗传学检测结果,并复习相关文献。结果 患儿,男, 1岁3个月,因智力运动发育迟缓就诊。患儿毛发浓密,眼距宽,眼 裂下斜,短人中,上唇短,多线及通贯掌纹,关节过伸,肌张力低。中性粒细胞减少。头颅磁共振成像示双侧脑室扩大,脑 外间隙增宽。基因检测显示患儿VPS13B基因存在复合杂合变异c.3863delC(p.T1288fs)及c.5082delT(p.S1694fs),分 别来自表型正常的父母。两个变异位点均未见报道,相关软件预测为致病变异。结论 患儿确诊为Cohen综合征,此研 究扩展了Cohen综合征患者VPS13B基因变异谱。
