Chromosome 5 duplication may be caused by external environment, chemical and biological factors, heredity and other reasons.
1. External environment: there may be some substances in the external environment that are not good for health, and if you are in such a situation for a long time, it will easily lead to chromosome abnormality.
2. Chemical-biological factors: If you are exposed to an environment or objects full of radiation, X-rays, or pharmaceutical agents for a long period of time, it is also easy to cause chromosome 5 to be duplicated.
3. Heredity: If there is a chromosome duplication in the mother or grandparents, then heredity will also lead to the possibility of this condition in the offspring.
If any chromosome abnormality is found, then it is recommended to seek medical treatment in time to treat the symptoms.
