摘要
目的研究共同性外斜视家系中患者ARIX基因多态性及其意义。方法对收集到的共同性外斜视一家系中所有成员提取外周血DNA,进行PCR扩增,DNA测序,测序结果与GenBank中人ARIX基因序列进行同源性比较。结果家系中所有患者在ARIX基因外显子2处发生G116A改变,为同义突变,2例正常人也出现此改变。结论 ARIX基因可能不是本研究中所收集的共同性外斜视家系的致病基因。
Objective To investigate the ARIX gene polymorphisms in patients with concomitant extropia in a family and its association with clinical characteristics of these patients. Methods The genomic DNA of all family members was extracted from peripheral blood leukocytes and amplified with PCR. The PCR products were purified for DNA sequencing. DNA sequences were aligned with the human ARIX gene sequences registered in GenBank. Results A 116G 〉 A synonymous mutation of exon 2 in six patients in the pedigree. Two of the six normal individuals have the mutation also. Conclu- sion The ARIX gene maybe not virulence gene in this pedigree.
