1. Can single-gene genetic diseases be treated? It can be cured. Is there any way to avoid it?
It can be cured, provided it is discovered in time. Genetic diseases are caused by the lack of enzymes controlled by genes, which affect the synthesis of certain substances in the body, or affect metabolism, which further affects organ function, causing the accumulation of metabolites in the human body and causing symptoms of poisoning. Timely discovery will lead to corresponding treatment plans. This can be avoided by doing premarital consultation, physical examination, and avoiding the combination of similar genetic diseases.
2. Do polygenic genetic diseases conform to the laws of inheritance
Overall Generally speaking, both single-gene genetic diseases and polygenic genetic diseases are in line with the rules of genetic diseases. However, there are many uncertainties in polygenic genetic diseases, such as gene exchange before the first division, and the union of sperm and egg. Sperm and eggs may also carry genes, causing uncertainty. In addition, chromosomal variation may also lead to genetic variation, so polygenic genetic diseases sometimes show incomplete genetic disease patterns.
3. What is the method for detecting gene mutations in single-gene genetic diseases? Please introduce it
The methods for detecting gene mutations in single-gene genetic diseases include: genetic screening, karyotype analysis, and chromosome. Pedigree analysis is the basis for the diagnosis of genetic diseases. A pedigree is a diagram used to show the occurrence of a certain disease in various members of a patient\’s family. Indications for chromosome testing, the core analysis is to determine the chromosomeimportant method of disease. Gene mutation detection is based on establishing a series of electrophoresis, DNA analysis, DNA conformation or melting characteristics, or using DNA mutation and replication characteristics to analyze DNA mutations.
4. Can polygenic genetic diseases be treated
Polygenic Some genetic diseases can be treated and some cannot. Polygenic genetic diseases refer to genetic diseases caused by the cumulative effect of two or more disease-causing genes. Compared with single-gene genetic diseases, polygenic genetic diseases are more affected by environmental factors. Polygenic genetic diseases will show familial aggregation, and their incidence in families will increase. For example, the prevalence of schizophrenia in families is significantly higher than in the general population, and the closer the family relationship, the higher the incidence.
The sharing of this issue about single-gene genetic diseases and whether single-gene genetic diseases can be cured ends here. If your problem is solved, we very happy.
