The health of the baby is a thing that everyone wants. Parents do not want some genetic diseases to be inherited to the next generation.What common genetic diseases will be inherited to the next generation?Know this together!
1. Hyperlipidemia, hypertension
The two diseases of hypertension and hyperlipidemia are hereditary. If one of the parents has hypertension or hyperlipidemia, if one party has a hypertension or hyperlipidemia, the chances of their next generation will be about 50 %;If these diseases, the chance of children is as high as 70 %, which is enough to prove that the geneticity of cardiovascular disease is very strong.
2. Hemathery disease
The disease of hemophilia is also a typical accompaniment genetic disease, which will only be inherited to the boy.Girls will become genetic carriers of hemophilia, and they will pass the pathogenic genes to future generations. Among them, male descendants will be sick.Most of the sick men will die after adulthood, without continuing this gene.
3. Congenital deaf dumb
Congenital deafness is also a genetic disease, which is determined by chromosomes.Half of the congenital deaf and mute gene comes from half of his father from women. This means that if both parents are deaf, their children will also be deaf.
Many of the nasal diseases are caused by genetic. For example, allergic rhinitis is a common genetic disease. According to statistics, if one of the parents suffers from allergic rhinitis, the next generation of children will be about about aboutOne -third will suffer from this disease; if both parents have allergic rhinitis, the risk of this disease in the next generation is as high as two -thirds.
With the development of science, many hereditary diseases can be found during pregnancy tests. There are three common genetic testing methods: biochemical testing, chromosome analysis, and DNA analysis.
Biochemical testing is to detect blood, urine, amniotic fluid, and amniotic cell samples through chemical measures, check whether related proteins or substances exist, and can detect whether there are genetic defects.
The chromosomal analysis is to directly detect the number of chromosomal numbers and abnormal structures, rather than check the mutations or abnormalities of a gene on a certain chromosome, which is used to diagnose whether the fetus has abnormal chromosomes.
The DNA examination is a hereditary disease caused by the abnormalities of a single gene, such as Hennington’s disease, etc. The cells analyzed by DNA come from blood or fetal cells.
These tests can be checked in some hereditary diseases, but these genetic diseases such as hypertension, hyperlipidemia, and rhinitis generally take a few years or even decades to appear, and these diseases cannot pass the fetal period.Check it out.If you want to prevent these diseases, pay more attention to lifestyle and regular physical examinations in daily life. There are timely intervention treatment when abnormalities are found.
