However, the current Nature Genetics report associates SLE with a polymorphism at gene TNFSF4.
然而，当期《自然-遗传学》杂志报告sle与TNFSF4基因多态性有关。
For example, transfer of virulence gene and transmission of drug-resistant gene mediated by a phage results in gene polymorphism of bacteria, which is an important problem in medicine and genetics.
如由噬菌体介导的细菌毒力基因的转移、细菌耐药基因的传递等导致了病原菌基因表型的多态性，这在医学与遗传学中是一个日益严峻的重要问题。
The individual variation may be caused by many factors, such as genetics, environment, disease stage and diet, etc, among which genetic polymorphism is a common and uncontrollable factor.
这种差异可能是由遗传、环境、疾病状态或饮食结构等诸多因素引起的。其中基因(遗传)多态性是导致药物代谢个体差异的较为常见且不可调控的因素。
