摘要: 目的 研究转录因子FOXP1在汉族孤独症患儿核心家系中的外显子突变,并进行初步的功能预测。 方法 288例孤独症患儿及生物学父母进行FOXP1外显子区域基因测序和拷贝数变异(copy number variation,CNV)检测;使用POLYPHEN及SIFT等软件进行功能预测。 结果 4例患儿的FOXP1基因外显子区域发现4个错义突变,包括P42S,H53Q,L68R和M590V。在CNV检测中为阴性结果。通过功能预测发现,FOXP1的四个罕见突变可能不会对FOXP1编码蛋白产生重要影响。 结论 汉族人群中,FOXP1基因可能不是孤独症的主要致病基因。

Abstract: Objective To study the transcription factor FOXP1 exon in the Han Chinese children with autism nuclear families,and finish the initial function prediction. Methods The gene sequencing in FOXP1 exon regions of 288 cases of children with autism and their biological parents were conducted to detect the copy number variation (CNV) of FOXP1.The POLYPHEN and SIFT software were used to do the function prediction. Results In 4 patients,four missense mutations were found in FOXP1 exon region,P42S,H53Q,L68R,and M590V.And there were the negative results in the detection of copy number variation.After the function prediction,the four rare mutations might not have an important impact on the protein. Conclusion In the Han Chinese population,the FOXP1 gene may not be one of the important autism disease-causing genes.
