There likely isn't one single cause, but a combination of genetic and environmental risk factors that contribute.

病因应该不止一个，而是基因与环境风险因子结合所导致的。

A rocky home life had no effect on the rate of diagnosis in the group without genetic risk factors.

在没有遗传危险因素的人群中，不稳定的家庭生活对诊断率没有影响。

There likely isn't a single cause, but a combination of genetic and environmental risk factors that contribute.

很可能没有一个单一的原因，而是遗传和环境风险因素的综合作用。

In 2020, research by Zeberg and Paabo found that a major genetic risk factor for severe COVID-19 came from Neanderthals.

2020年，泽伯格和帕博的研究发现，严重新冠肺炎的一个主要遗传风险因素来自尼安德特人。

But other factors can increase or reduce genetic risks.

但其他因素可以增加或减少遗传风险。

Escaped farmed fish also pose a genetic risk to their wild cousins.

逃脱的养殖鱼也对它们的野生表亲构成遗传风险。

There likely isn’t one single cause, but a combination of genetic and environmental risk factors that contribute.

可能不是一个单一的原因，而是遗传和环境风险因素的结合。

And, with any level of genetic risk, a good diet, regular exercise, limited alcohol use and no tobacco use made dementia less likely.

此外，无论遗传危险高不高，只要饮食健康、经常运动、饮酒有节制、不抽烟，那么患阿兹海默症的风险就会更低。

For example, Ashkenazi Jewish ancestry is associated with higher rates of BRCA-1 mutations, which is a genetic risk factor for breast cancer.

例如，德系犹太血统与较高的 BRCA-1 突变率有关，而 BRCA-1 突变是乳腺癌的遗传风险因素。

It showed that people with high genetic risk and poor health habits were about three times more likely to develop dementia than those with low genetic risk and good habits.

研究表明，遗传危险高的人以及卫生习惯差的人，其患阿兹海默症的可能性是遗传危险低、生活习惯好的人的近3倍。

Genetic risk factors include being a woman and having genes that encode a specific type of immune molecule called HLA-DR2 which is used to identify and bind to foreign molecules.

基因危险因素有身为女性和一种编码特殊类型的免疫分子——HLA-DR2的基因序列（常常识别和结合外源分子）。

For those with very low genetic risk, no amount of exposure to environmental risk factors will lead them to develop schizophrenia; for those with very high risk, moderate additional risk might tip the balance.

对那些基因风险很低的人来说，不论多少环境因子都不会使他们患上精神分裂症；而对于患病风险非常高的人，中等的额外风险也可能会破坏这种平衡。

There are also genetic risk factors like having the BRCA-1 or BRCA-2 mutation, which are both autosomal dominant mutations, which in addition to ovarian cancer, carry with them an increased risk of breast cancer.

还有遗传相关的风险因素，如BRCA-1和BRCA-2突变，它们都是常染色体显性突变；除了卵巢癌之外，携带它们也会增加乳腺癌患病风险。

The thing that some do blame it on, DHT, can increase from many factors other than creatine, like exercise, and DHT seems to play a role only if you are already at a genetic risk of losing your hair.

有些人确实将此归咎于 DHT，但 DHT 也可以从肌酸以外的许多因素中增加，比如锻炼，而 DHT 似乎只有在你已经有脱发的遗传风险时才会发挥作用。
