The top ten and genetic diseases

Keywords: genetic diseases

First, let's look at what is the disease genetic tendency in the presence of the disease,? is not equal. Everyone on the susceptibility of the different diseases, as well as on the lifestyle of tolerance is not the same. Just like each person born with high Union difference, each with different diseases "affinity". For example, some people never-smoking finally got lung cancer, but some people taking a lifetime of smoking finally didn't have lung cancer, this makes some smokers "luck", think smoking may be okay.　　In fact, this is the family genetic susceptibility in work. Recognizing this, we can trace family members of ill, knowing what are the risk of diseases, thus targeted prevention.　　For example, if your family many relatives suffer from diabetes, then you have the chance of diabetes than ordinary people, should pay special attention to monitoring and prevention of diabetes. So, what are common diseases are genetic tendency? if you belong to these diseases in high risk populations, and how to plan ahead, blocking its continuation in himself? 1. genetic risk of hypertension: ★ ★ ★ ★ ★ currently most scholars believe that hypertension is a hereditary disease of multiple genes.　　Pedigree by hypertension found that parents who are suffering from hypertension, their children will suffer from hypertension probability of up to 45 per cent; the parents suffer from hypertension patient, the probability of a child suffering from hypertension is 28%, while parents Normotensive their children suffering from hypertension probability of only 3 per cent. 2. genetic risk factor for diabetes: ★ ★ ★ ★ ★ diabetes has distinct genetic susceptibility (especially on the most common clinical 2 diabetes). Family study found that a positive family history of diabetes mellitus, remarkable for its diabetes prevalence is higher than the population of family history was negative.　　While parents are their children with diabetes, diabetes is the ordinary people of 15-20 times. 3. genetic risk of Dyslipidemia: ¡ï ¡ï ¡ï lipid metabolism has many reasons, one of these is the genetic factors. With the development of medical science, has now found a considerable part of Dyslipidemia patients there are one or more genetic defects.　　By genetic defects induced lipid abnormality with familial, with distinct genetic tendency, clinically known as familial Dyslipidemia. 4. genetic risk for breast cancer: ¡ï ¡ï ¡ï breast cancer have obvious family genetic tendency. Epidemiological survey found that 5% ~ 10% of breast cancer is the family. If there is a close relative of breast cancer, increased risk of illness 1.5 ~ 3 times; if there are two close relatives, the prevalence of breast cancer will be increased by 7 times.　　Age of onset, relatives in the risk of breast cancer. 5. genetic risk for gastric cancer: ★ ★ ★ gastric cancer patients have distinct familial. The survey found that first-degree relatives of patients with gastric cancer (i.e. parents and brothers and sisters) have the risk of gastric cancer than the general population on average 3 times.
