| 7. | Although many genetic mutations have been suggested as causes or risk factors for parkinson ' s disease , the low penetrance of some mutations and the low disease concordance in relatives suggests that there must be interactions between multiple factors
虽然许多遗传突变已经被认为是帕金森氏病的危险因素，但是一些突变基因的外显率低，家族相关的发病率也低，这说明一定有多因素的交互作用。 |
| 8. | Some studies looked at homocysteine and the occurrence of heart attacks and strokes in large numbers of people ( cohort studies ) , some focused on people with a common genetic variant which increases homocysteine levels to a small extent ( genetic studies ) , while others tested the effects of lowering homocysteine levels ( randomized controlled trials )
一些研究着眼于大样本人群中同型半胱氨酸与心脏事件和卒中的关系，一些重点研究发生共同遗传突变导致同型半胱氨酸发生轻度升高的人群，还有就是研究降低同型半胱氨酸水平的作用（随机对照实验） 。 |
