摘  要:
为建立一种快速高通量的荷斯坦奶牛脊柱畸形综合征(Complex vertebral malformation,CVM)变性高效液相色谱(DHPLC)的分子检测方法,根据CVM是由于SLC35A3基因第4外显子559位处发生G→T突变的遗传学基础,设计了1对引物对3种不同基因型的基因材料PCR扩增,利用Navigator软件分析确定检测温度、洗脱浓度及梯度等条件,建立检测方法。对55份进境荷斯坦奶牛血样进行检测,发现有1例为隐性基因携带者,将PCR产物送测序,结果与DHPLC检测结果一致。研究表明,PCR-DHPLC是一种可有效用于荷斯坦奶牛脊椎畸形综合征检测的新方法。

摘  要:
Complex vertebral malformation(CVM) is an autonomic recessive disease caused by G→T mutation in the SLC35 A3 gene. To develop a rapid and high-flux molecular method for detection of CVM,one pair of specific primers was designed according to the gene sequence of the bovine SLC35 A3 gene. The PCR fragments of three different genotypes were analyzed by DHPLC under the conditions predicted by the Navigator software. 55 blood samples from imported Holstein cows were detected by the established protocol. One CVM carrier in the55 samples was identified. The result of sequencing of the PCR product of the CVM carrier was consistent with that of DHPLC. This study provided a more reliable and useful method for detecting CVM and also offered a theoretical basis for molecular diagnosis of CVM in Holstein cows.
