目的:探讨应用微阵列比较基因组杂交(array-CGH)技术诊断7p15.3p22.1微缺失,并分析其临床表现和7p15.3p22.1缺失的相关性。方法对1例常规染色体核型分析未见异常的新生儿采用array-CGH技术进行全基因组拷贝数变化(CNVs)分析。结果发现患儿7p15.3p22.1片段缺失,位于chr7:6777262-23981753,经与数据库比对为致病性缺失片段。结论 array-CGH可作为常规G显带核型分析的有益补充,应用于临床细胞遗传诊断中。
目的:探討應用微陣列比較基因組雜交(array-CGH)技術診斷7p15.3p22.1微缺失,併分析其臨床錶現和7p15.3p22.1缺失的相關性。方法對1例常規染色體覈型分析未見異常的新生兒採用array-CGH技術進行全基因組拷貝數變化(CNVs)分析。結果髮現患兒7p15.3p22.1片段缺失,位于chr7:6777262-23981753,經與數據庫比對為緻病性缺失片段。結論 array-CGH可作為常規G顯帶覈型分析的有益補充,應用于臨床細胞遺傳診斷中。

Objective To investigate the diagnosis of a case with 7p15.3p22.1 microdeletion by applying array-based comparative genomic hybridization (array-CGH) and to analyze the relationship between the clinical manifestations and 7p15.3p22.1 microdeletion. Method Array-CGH technique was used to detect genomic copy number variations (CNVs) in an infant with normal karyotype after conventional chromosomal karyotyping. Results Array-CGH detected 7p15.3p22.1 deletion (chr7: 6777262-23981753), which was confirmed as pathogenic CNV after comparative analysis with database. Conclusion Array-CGH could serve as a useful complement for G-banding to be used in the clinical cytogenetic diagnosis.
