Color deficiency is mainly due to X-chromosome-linked recessive inheritance, and the disease is characterized by familial aggregation.
Color deficiency is a disorder of color vision, in which the patient may have a reduced ability to recognize colors. It is mainly due to genetic inheritance, and the vast majority of patients are due to X-chromosome recessive inheritance.
When a male with dyschromia passes on the gene on the X chromosome to his daughter, the daughter has the gene on a single X chromosome but does not develop the disease. However, the daughter passes on the gene to the next generation of males who have the disease gene on a single X chromosome and develop the disease.
In the case of a female with color deficiency, the presence of the gene on a single X chromosome does not cause disease. Only if the mother carries the gene and passes on the X sex chromosome that carries the gene to her daughter, and the father also has color deficiency, can the daughter develop the disease when she develops two X chromosome genes for color deficiency.
Once the diagnosis of dyschromia is confirmed, the patient should actively cooperate with the doctor to take relevant treatment measures.
