Brief introduction of chromosome abnormality

Chromosome abnormalities, also known as chromosome dysplasia, refer to the abnormal number and structural aberration of chromosomes. Chromosomes are composed of DNA and proteins, and most genes are located in the DNA of chromosomes. Chromosome is the basic substance of nucleus and the carrier of gene. Chinese American Jiang Youxing (1956) identified 46 human chromosomes, and Caspersson et al. (1970) first published human chromosome banding photos. Since the International Conference on Chromosome Nomenclature in Paris in 1971, more than 3000 kinds of chromosome abnormalities and structural aberrations have been found, and more than 100 kinds of chromosome disease syndromes have been confirmed. Mental retardation and growth retardation are the common characteristics of chromosome diseases.
