背景情况:

猪内源性逆转录病毒 (PERV) 在异种移植中构成人类细胞感染的风险.
减少猪中的PERV复制数对于安全移植器官至关重要.
越南本土猪品种正在研究他们的PERV遗传特征.

研究的目的:

为了估计越南本土猪中PERV副本数的遗传性.
评估传统育种在减少PERV多基因拷贝数量的有效性.
探索用于减少猪PERV的替代技术.

主要方法:

基因组遗传性估计使用限制最大概率方法和基因组关系矩阵.
养殖猪种群减少PERV多基因拷贝数量超过三代.
在选定的猪种群中分析PERV拷贝数和多基因流行率.

主要成果:

四个PERV相关基因的基因遗传概率估计在0.27到0.71.7之间.
聚基因表现出高遗传性 (0.59),但常规选择产生的拷贝数量最小减少.
减少PERV副本数量的进展有限,这表明传统育种方法存在挑战.

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
