2型固有淋巴细胞(ILC2)是一种免疫细胞,可分泌辅助性T细胞2,参与呼吸道过敏、蠕虫感染等疾病的发生发展。牛奶蛋白过敏(CMPA)是一种口服耐受建立失败而引起的多器官甚至全身过敏状态。受饮食方式和环境变化的影响,肠道微生态失衡导致儿童中CMPA的发生率逐年攀升。近年来对免疫相关细胞群体的研究表明,ILC2在肠道局部免疫中起重要作用。ILC2的激活和功能表达离不开肠道菌群产生的细胞因子和代谢物,未来对过敏肠道内ILC2的代谢组学研究,或将成为治疗CMPA的靶细胞。

目的分析1例Helsmoortel-Van der Aa综合征(Helsmoortel-Van der Aa syndrome,HVDAS)患儿的临床特征与遗传学特征。方法对患儿及其父母进行基因变异分析,通过文献回顾总结归纳HVDAS患者的临床表型与变异类型。结果患儿表现为特殊面容,伴有自闭症谱系障碍、智力障碍和运动发育迟缓,同时双足第二趾向内卷曲,既往未见报道。基因检测提示其存在ADNP基因杂合变异c.2157C>G(***719*),其父母均未见此变异,根据美国医学遗传学与基因组学学会指南评估为致病性变异。文献报道的80例HVDAS患者几乎均存在不同程度的行为异常、智力障碍、语言及运动发育滞后等症状,神经系统、胃肠道系统及眼部频繁受累。ADNP基因的变异类型主要为移码变异与无义变异,热点变异包括***719*、***832Lysfs*81及***730*等。结论患儿的临床表型与ADNP基因杂合新发变异高度相关,进一步拓展了HVDAS的表型谱。由于HVDAS可导致多个系统受累、表型异质性较大,可结合基因检测技术对其进行确诊。

目的探讨1例表现为反复感染、多发畸形以及异常面容的患儿的遗传学病因。方法对患儿及其父母进行家系全外显子组测序。结果患儿以"发热咳嗽"为代主诉就诊,具有睑裂细长、睫毛长等特殊面容。基因检测提示其KDM6A基因发生非三联体缺失,既往未见报道。该变异可导致移码并提前终止转录,父母该位点为野生型。患儿因免疫低下导致严重的继发性肺炎,经抗感染及免疫球蛋白治疗后好转。结论结合实验室、影像学及基因检测结果,患儿最终被诊断为Kabuki综合征2型。Kabuki综合征相关的免疫缺陷可能导致常规抗感染治疗无效,值得临床关注。
