  But there are several recent studies that find that certain variations
  但是最近有些研究发现血清素传递基因的特定变化

  or polymorphisms on the serotonin transporter gene predict
  和多态性可以预测

  who will become depressed in the face of stress.
  谁会在面临压力的时候患上抑郁症
• 
  
  So, a classic study was done by Avshalom Caspi and colleagues,
  艾弗谢罗姆·凯蒲赛和同事一起进行了一个很经典的研究
• 
  
  and they found that people who have one
  他们发现在血清素传递基因上
• 
  
  or two of what's called the short allele on the serotonin transporter gene--
  有一个或两个等位基因的人
• 
  
  so this is a particular variation on the serotonin transporter gene--
  这是血清素传递基因上的一个特殊变化
• 
  
  if they had one or two of these short alleles
  如果他们有这样一个或两个等位基因
• 
  
  and they were confronted with stress,
  当他们面对压力的时候
• 
  
  they were more likely to develop depression.
  他们更容易发展成抑郁症
• 
  
  But it's important to sort of dissect this.
  但重要的是还需要深入研究

  So people who had--it didn't really matter which of these genes you had.
  这并不真的与你有什么样的基因有关
