歪嘴哭面容新生儿临床特征及遗传学检测

摘要

目的 分析歪嘴哭面容(asymmetric crying facies,ACF)新生儿临床特征及遗传学检测结果.方法 回顾性分析2007年1月至2016年12月本院新生儿科收治的ACF患儿母亲资料、出生时情况、临床表现、染色体荧光原位杂交(fluorescence in situ hybridization,FISH)和基因芯片检测结果.结果 研究期间共收治ACF患儿32例,其中男24例,女8例;单胎27例,双胎或多胎5例(患儿同胞胎均无ACF).16例患儿母亲有自然流产或人工流产史,患儿出生时均无产伤及窒息抢救史.左侧病变16例,右侧病变16例.独立ACF 7例,合并单一系统畸形7例,合并多系统畸形18例,合并畸形包括耳部畸形11例、面颈部畸形6例、心血管系统畸形19例、泌尿系统畸形3例、消化系统畸形3例、神经系统影像学检查异常7例、免疫及内分泌异常3例.10例患儿行遗传学检测,4例异常.其中8例行FISH检测,2例存在22q11.2微缺失;1例行基因芯片检测发现22q11.21区域杂合缺失;1例行FISH检测未发现22q11区域缺失,但基因芯片检测发现22q21区域杂合缺失.6例死亡,其中5例合并多个系统畸形.结论 ACF为微小面部畸形,但常合并其他系统先天畸形,早期行遗传学检测和多系统畸形筛查尤为重要.%Objective To study the clinical and genetic characteristics of neonatal asymmetric crying facies (ACF).Method From January 2007 to December 2016,clinical data were retrospectivelyreviewed in patients with ACF admitted to Neonatal Unit of Xinhua Hospital.The data included maternalpregnancy and delivery history,clinical manifestation,results of chromosome florescent in situ hybridization(FISH) and gene chip test.Result Among 32 patients with classic ACF,8 were female and 24 weremale.5 cases were one of the twins or muhiplets.16 patients were born from mothers with history ofspontaneous abortion or induced abortion.16 patients presented with ACF on the left side and 16 patients onthe right side.7 patients had single ACF malformation,7 with malformation of another organ,and18 patients with malformation of more than two other organs.Combined malformation included earmalformation in 11 cases,facial malformation in 6 cases,cardiovascular malformation in 19 cases,urinarytract malformation in 3 cases,digestive system malformation in 3 cases,abnormal nervous system image in7 cases,and immune/endocrine system abnormality in 3 cases.10 patients received genetic analysis withFISH and/or gene chip tests and 4 patients had positive results.Among the patients who completed geneticanalysis,8 patients received FISH test and 2 patients had 22q11.2 distal deletion.1 patient hadheterozygous deletion in 22q21 region using gene chip test after he got a negative result with FISH.Amongthe 32 cases,6 patients died until now,among them,5 patients had multi-organ malformation.ConclusionACF is a tiny facial deformity,however it is often associated with other congenital malformations.Earlygenetic detection and systematic multiple malformations screening are particularly important for diagnosis andprediction of prognosis.
